L3Harris Technologies is on track to begin building the U.S. Air Force’s first Navigation Technology Satellite-3 (NTS-3) after completing the program’s critical design review.
According to L3Harris, it will integrate the program’s experimental payload with an ESPAStar Platform, planned for launch in 2022. The system is designed to augment space-based position, navigation and timing (PNT) capabilities for warfighters.
The NTS-3 payload features a modular design, and the experiment will demonstrate capabilities that can be accomplished through a stand-alone satellite constellation or as a hosted payload.
“Collaboration with our customers has enabled us to move rapidly through important milestones to design this experimental satellite,” said Ed Zoiss, president, space and airborne systems, L3Harris. “Our goal is to deliver new signals to support rapidly evolving warfighter missions.”
The Space Enterprise Consortium selected L3Harris for the $84 million contract in 2018 as the prime system integrator to design, develop, integrate and test NTS-3. The NTS-3 will examine ways to improve the resiliency of the military’s PNT capabilities. It will also develop key technologies relevant to the GPS constellation, with the opportunity for insertion of these technologies into the GPS IIIF program, L3Harris said.
The program is a collaboration with the Air Force Research Laboratory, Space and Missile Systems Center, U.S.Space Force, and Air Force Lifecycle Management Center.
A recently unclassified CIA drone program provides us with perspective on UAS development. Also, U.S. high-altitude surveillance capabilities are being tested, another record has been achieved, and an award for the U.S. Air Force space plane.
1960s CIA Bird-Drone
Back when the U.S. was flying U2 spy planes over the Soviet Union and Gary Powers was on Russian TV after being shot down, the CIA got to thinking of another approach for gathering airborne intelligence.
Project Aquiline was an early drone project aimed at making overflight much less conspicuous — because the drone was built to resemble a bird.
Project Aquiline was contracted to McDonnell Douglas, which produced five prototypes. (Photo: CIA Archives)The Project Aquiline bird drone in flight. (Photo: CIA Archives)
With a two-stroke engine driving a pusher-propeller and an 8-foot wingspan, five prototypes were built and tested through 1967-68. The concept was to fly at lower altitudes than the U2, carrying equivalent camera and electronic surveillance equipment, but to be very difficult to observe from the ground.
Although a two-stroke engine might have been somewhat noisier than a large bird, later phases of the program envisaged a miniature nuclear power source which presumably would have been much quieter with a relatively huge range.
The project began in 1966, and prototypes began operational testing in 1968. The prototypes established a range of around 130 miles, took high-resolution images and successfully returned to the control site.
However, with many stages of development still to go (the cost to complete was maybe too high), the project was canned in November 1971.
Maybe this initial “bird” concept is where the name of today’s high-altitude, long-endurance Global Hawk drone originated — who knows?
NASA High-Altitude Long-Endurance (HALE) UAVs
But the U.S. government seems to have other objectives than just high-altitude reconnaissance. NASA has operated the Global Hawk drone for science missions for a number of years, alongside the U-2 and ER-2 high-altitude manned aircraft.
Armstrong Flight Research Center operates two Global Hawks with support from Northrop Grumman out of Edwards Air Force Base.
Global Hawk is flown with a pre-loaded mission profile at upwards of 60,000 feet, sometimes for as long as 24 hours and more than 8,000 miles. Nevertheless, the aircraft is monitored over both satellite and terrestrial links, with direct sensor payload access throughout.

Global Hawk is powered by a Rolls-Royce AE3007H turbofan engine. It has a wingspan exceeding 116 feet, measures 44 feet from nose to tail, has a gross takeoff weight of 25,250 pounds and carries a 1,500-pound payload.
But this aircraft is massive compared to another recent high-flying project that NASA funded through a Phase I and II Small Business Innovation Research/Technology Transfer (SBIR/SBTT) program.
The Swift HALE unmanned aircraft system (Photo: Swift Engineering/NASA)
With the help of NASA’s Ames Research Center, Swift Engineering in San Clemente, California, completed a two-hour flight test on July 7 of its High-Altitude Long-Endurance (HALE) UAS, aiming to join the group of companies already in the high-altitude UAV club.
The 72-foot wingspan, solar-powered HALE weighs <180 pounds, carries a 10-15-pound payload and is destined to fly at up to 70,000 feet for more than 30 days.
This HALE aircraft is expected to complement existing NASA observation platforms and provide unique material alongside existing satellite data. Swift Engineering has been working with NASA Ames since 2016 on a proof-of-concept solar-powered UAS aimed at sustained flight for a month or more.
Swift researched solar panels and high-power, multiple-cycle rechargeable battery technologies to develop a system that could survive harsh temperatures as well as the radiation encountered at high altitude.
During the first of a series of flight tests at Spaceport America in New Mexico on July 7, operations at low altitude were completed to verify systems, aerodynamic control and power-system models. The July 7 flight was the first in a series to collect data and further validate the design.
With NASA, Swift has developed a UAS to not only meet observation objectives, but also one that aligns with the Federal Aviation Administration’s view of HALE deployment and maintenance during extended flights. For the test flight, the vehicle carried a NASA FluidCam for science missions, with a focus on mapping coastal reef systems.
NASA teams are exploring how aircraft such as Swift’s could perform as pseudo-satellites for air-quality monitoring, image coastal zones, map landslides and geologically active regions, and for real-time forestry and agricultural monitoring.
The next step in the development is expected to be a Phase III series of scientific observations at high altitude for days and even weeks.
Boeing X-37B Team Wins Collier Trophy
The Air Force/Boeing X-37B autonomous space plane has won the Collier Trophy for best in U.S. aeronautics/astronautics performance and safety in 2019.
The X-37B set a new 780-day on-orbit record and descended through the controlled U..S National Airspace System (NAS) to land at NASA’s Kennedy Space Center.
Initially launched in 2010, the reliable, reusable and unmanned X-37B has provided space access and subsequent analysis for a large number of key experiments.

The space plane has now broken its previous on-orbit record of 718 days and has orbited for 2,865 days and more than 1 billion miles in total. Originally designed for only 270 days in space, the X-37B has established endurance records in every one of its last five flights.
Since 1911, recipients of the Collier Trophy have included Orville Wright, the Apollo 11 lunar landing team, the International Space Station team, the U.S. Navy F/A-18E/F Super Hornet team and the Boeing 787, 777 and 747 passenger aircraft teams.
Intelligence Gathering
News about the 1960 CIA drone developments, aimed at gathering unobserved photo reconnaissance intelligence, provide new perspective on NASA’s current-day use of high-altitude observation assets. These are the same types of assets that the U.S. currently uses for intelligence gathering, despite being recently intercepted by Russian jets off the coast of Alaska. It makes for interesting aspects of drone history, along with new aspects of (very) high-altitude unmanned capabilities.
New SyncServer S650 M-Code secures military communication systems, radar and networks reliant on GPS signals

Threats from intentional jamming and spoofing of GPS signals, as well as cybersecurity risks to critical infrastructure, demonstrate the need for powerful and secure time and frequency systems that ensure continuing operability and performance.
Microchip Technology’s SyncServer S650 M-Code time server has received approval from the U.S. Air Force GPS Directorate of the Los Angeles Air Force Base for use in support of military communication systems, radars and networks.
M-code, an encrypted military signal broadcasted in GPS frequency bands, is required by congressional mandate for mission critical Department of Defense (DOD) applications in hostile environments. Microchip’s SyncServer S650 M-Code equipped time and frequency server provides a secure, accurate, flexible platform for synchronizing mission-critical electronic systems and instrumentation.
For DOD programs requiring jam-resistant, encrypted time and frequency signals from the GPS military M-code Precise Positioning Service (PPS), the SyncServer S650 M-Code is a secure time and frequency instrument with a fully integrated M-code GPS receiver.
“As the first time and frequency instrument enabling DOD compliance for M-code-based GPS systems, this technology demonstrates Microchip’s continuing commitment and investment in the security of time and frequency systems,” said Randy Brudzinski, vice president, Frequency and Timing Solutions business unit. “This time server represents a new level of security hardening built on Microchip’s proven commercial SyncServer S650 time server that provides extreme timing accuracy, security and flexibility.”
The SyncServer S650 M-code equipped time and frequency instrument is a rack mounted server device that synchronizes to the atomic clocks aboard GPS satellites via M-code. The S650 M-code leverages new technology to provide enhanced anti-jamming protection and further hardening against spoofing, providing greater accuracy, and improving operator ease-of-use for key loading.
Harder to jam than commercial CA-Code GPS, M-code provides a more secure signal than the commercial CA-Code or SAASM P(Y) signal, with greater accuracy. The instrument also is easier for operators to load crypto keys.

The SyncServer S650 M-Code can utilize Microchip’s FlexPort technology for multiport, user definable output signal configurations for Inter-Range Instrumentation Group (IRIG) timecodes, pulses and a variety of signal types essential for military communication, radars and network system synchronization. This is coupled with Microchip’s NTP Reflector technology for robust security, accuracy and reliability of network-based time services such as Network Time Protocol (NTP) and Precision Time Protocol (PTP). Other features include:
Four standard GbE ports, all with patented NTP hardware time stamping, with two additional 10 GbE ports optional
Contains most popular timing signal inputs/outputs standard in the base timing I/O module (IRIG B, 10 MHz, 1PPS)
Web-based management with high security cipher suite
Rubidium atomic clock or OCXO oscillator upgrades
Superior 10 MHz low phase noise options
Microchip has been delivering the SyncServer S650 to synchronize business critical and mission critical operations, across all industry segments, since its commercial introduction in 2016.
UAV developments are taking flight across the globe.
In one development, older technology might enable new capabilities for a pseudo-satellite UAV. Meanwhile, new technology adds significant landing capability to an Air Force drone. Finally, further trials are expected to help develop drone operational procedures and regulations in India.
Spain’s Skydweller moves to Oklahoma
An unmanned aircraft builder from Spain — Skydweller — is setting up operations in Oklahoma. This latest outfit to relocate is establishing its headquarters in Oklahoma City to develop a pseudo-satellite vehicle with a large payload capability.
For anyone who has kept tabs on the Airbus Zephyr, the UAVOS ApusDuo, The Aurora/Boeing Odysseus, or the Softbank/AeroVironment Hawk30 high-flying drone programs, you might have noticed that the stratospheric pseudo-satellite business is not easy. None have yet made it to true operational status — loitering for months at +60,000 feet and living off only sunlight, while carrying significant payloads to provide communications services. That said, some trials to date have apparently been quite successful.
All those existing UAVs are huge, flimsy, flex-wing aircraft that take an inordinate amount of care to handle in the difficult phases of take-off and landing. Airbus’ second prototype crashed in Australia in October 2019, and several other companies’ earlier prototypes have crumpled somewhat when they inadvertently contacted the ground.
Now enter Skydweller. Skydweller is designed to carry a relatively large payload and fly persistently in the stratosphere.
The payload includes one or more communications relays: 4G/5G cellular, day/night full-motion video, satellite communication, and imaging radar. This looks like it could be one capable vehicle. The makers hope to capture business in commercial and government telecommunication, geospatial, meteorological and emergency operations. Skydweller has apparently been around since 2017 and has a lot of capability, so let’s see how they do with their new venture in Oklahoma.
If you were wondering where this technology came from, it is today’s carry-over of the famous around-the-world flight by the Solar Impulse aircraft from 2016, which circled the globe without fuel, using electrical power generated by solar cells on its wings.
GA Makes Improvements with Reaper
In another life, I was quite attuned to what it took to “automatically” land a passenger jet, so a recent release from General Atomics (GA) about improving the auto-landing system on Reapers (new-generation Predators) caught my eye. GA has a U.S. Air Force contract to update these unmanned reconnaissance/attack drones with the latest and greatest, so making a working system better is one of those improvements.
Actually, GA made three changes. The first enables the drone to divert to an alternate landing zone if the planned landing area is compromised — another word to express the possibility that hostile action or weather forced home base to send the vehicle elsewhere. Quite clever, in that the alternate site might not have a ground control station, along with someone who can fly the aircraft.

The ground pilot at home base has to either enter coordinates for the new alternate landing zone and the aircraft flies there and lands itself, or he needs to overfly the landing zone so that the Reaper can collect its own waypoint with which it can automatically align and land.
The second improvement has increased the speed limit of the cross wind in which the drone can land
The third enhancement allows the drone to land heavier than previously — both essential elements of being able to divert in an emergency, when weather may be poor and the aircraft could be carrying unused ordnance and fuel.
All this is a far cry from landing civilian air transports with GPS-based guidance, which is much more restrictive and with a whole mess of mathematical probabilities of the unlikeliness/likeliness of failure. Not so much for a Reaper drone on a mission during a “time of unrest.”
Home Deliveries in India
For those of you eagerly waiting for Amazon to start speedy deliveries of your online orders by drone, or Grubhub to drop in with an order of curry in a package dangling from a friendly unmanned air vehicle in your yard, there may be hope… especially if you live in India.
Following our earlier report of anticipated food deliveries by drone in India, more trials are leading to regulations and control systems. Altitude Angel from the United Kingdom has teamed with Indian Sagar Defence Engineering for a series of beyond-visual-line-of-sight (BVLOS) drone trials.
Altitude Angel’s GuardianUTM platform will be used to monitor and control these flights through real-life scenarios. Scenarios include medical and cargo transport, surveillance operations, survey and mapping, and search-and-rescue operations. Sagar will operate the cargo carrying drones; feedback from the GuardianUTM system will enable the BVLOS flights.
While the Indian government has begun to grant permission for some commercial UAV undertakings, the intent is apparently to use the output from the Sagar/Altitude Angel BVLOS trials, taking place August through October, to help develop regulations for safe operation of drones over increasingly longer distances in Indian airspace.
To sum up, intellectual property from an around-the-world photo-voltaic airplane may become a substitute for low-cost satellite TV and Wi-Fi, while auto-land is old hat for a Predator cousin and the Air Force has gained even greater landing flexibility for a principle recon/attack drone.
Finally, we can expect at least one continent to get to regulations that allow drone deliveries to become a reality at last. As usual, there is a lot cooking in drone-land….
A drone-versus-piloted attack aircraft, deliveries of medical supplies in North Carolina, unmanned meal deliveries in India and anti-drone protection for the Kennedy Space Complex are just a small sample of unmanned air vehicle news this month.
Even the U.K. BBC TV network picked up the news over the weekend that the U.S. Air Force (USAF) plans to pit an unmanned drone against a manned fighter aircraft, maybe even as early as July next year. The candidate fighter drone is thought to come from the USAF’s “Skyborg” research program — a wide ranging initiative aimed at incorporating artificial intelligence (AI) into unmanned vehicles which can out-think and out-fight the opposition.
The logic seems to be that if you could somehow ‘can’ all the experience of today’s pilots – somehow distill all their knowledge and stuff it into electronic memory and have AI use this data-base – then an unmanned fighter drone would somehow do better in combat against a hostile, manned aircraft. Probably a good idea, but how could it be made to work?

And the prime candidate to try all this is out could be the “Loyal Wingman” which was recently rolled out by its manufacturer Kratos. With a target price-tag of only $2 million each (for qty 100), USAF apparently foresees a future with lots of these “disposable’”guys accompanying the manned F-18, F-35, F-22 and future fighters into battle. Perhaps the airborne pilot could even coach his unmanned colleagues through an upcoming dogfight, augmenting the onboard knowledge carried by the drone? Seriously Si-Fi sounding stuff, but its apparently already well on its way.
And would current day autonomous drone operations count as using AI? Well such a drone uses a GNSS nav system and an operator pre-programs a route prior to launch, which the drone then refers to when airborne — even dropping off a package on cue when it arrives at destination, and turning round to fly the same route back home. So referring to an on-board waypoint data-base and executing a beyond visual line of sight (BVLOS) flight on its own — its somewhat limited AI, but the drone is independently doing a task once instructed.
Which brings us to the recent pandemic-related operations that operator Zipline has just begun running out of Kannapolis, North Carolina – from a vacant lot near a Novant Health logistics center — to the Huntersville Medical Center. With only regular capability to operate in accordance with Part 107 regulations, Zipline applied for a waiver to not only fly around population centers, but also to fly beyond visual line of sight (BVLOS). The Federal Aviation Administration (FAA) granted emergency authorization for Zipline to support Novant’s hospital and clinic COVID-19 response.
Fortunately, Zipline is coming off over four years of proven medical drone delivery operations in Rwanda and Ghana, so they have very credible capability to perform similar deliveries in North Caroline. Its possible that FAA took this excellent operational record into account in granting this Zipline waiver.
Nevertheless, Novant and Zipline plan to continue with their efforts to gain full FAA Part 135 authorization to regularly operate this medical package delivery service to Hospitals and Clinics in North Carolina. Meanwhile, this first of a kind long-range BVLOS service in the U.S. will continue to gather more airborne miles each day and demonstrate good confidence in safety and reliability. With over 1.8 million miles already flown during their African medical delivery service, Zipline is apparently coming from an established baseline capability.
In India — a country which has been testing drone services for the express deliveries of food to people’s homes — looks like they are ready to see if drones can be given the OK to operate all the time. The Directorate General of Civil Aviation (DGCA) has authorized a consortium of 13 companies to test drones flying BVLOS over longer distances to complete deliveries. DGCA apparently may have also been motivated to speed up shipments during the COVID-19 pandemic and SpiceXpress, one of the consortium members, will initially focus on delivering medical emergency/essential supplies after the trials are complete.
But overall, the objective for most consortium members is to get approval for meal deliveries by drone to become common practice in India. This will depend on the reports which the trial participants are required to submit to Airport Authority of India by September 30, 2020 from at least 100 hours of flight operations — hopefully without any serious incidents.
Not sure if everyone watched the SpaceX/NASA Demo-2 launch of the manned Dragon capsule on May 30, but I was glued to the NASA TV broadcast throughout. A truly significant event with not only a manned launch to the ISS by a commercial company, but a launch from Kennedy Space Center pad 39A — the first in nine years from U.S. soil.
Turns out we managed to get a ‘drone’ angle into the launch — or actually an absence of pesky drone interlopers at the launch site. Kennedy has been operating an anti-drone system for several previous launches — detecting and alerting any drone activity within the restricted airspace volume around pads 39A &B.
A mobile, all-weather Moog “Gauntlet” detection/alert system has been deployed for some time at Kennedy, watching for anything drone like within the confines of the launch area. The system is apparently visual, records evidence and provides alert indications over a secure VPN network, presumably to launch control and Kennedy security.
So this month we have news of a potential UAV-manned aircraft showdown, long-range drone deliveries of medical supplies in the U.S., Indian delivery drone qualification, and a drone detection system in use to protect the recent SpaceX crewed launch to the ISS. There is a lot going on, with high levels of complexity and good news in the fight against the pandemic for at least one hospital group in North Carolina.

The U.S. Air Force in September will begin testing on F-16’s an alternative position, navigation and timing (PNT) solution that uses the Earth’s magnetic anomalies.
The navigation technique, dubbed MAGNAV, is being researched at the Air Force Institute of Technology (AFIT), reports Forbes.
Air Force Major Aaron J. Canciani, an Assistant Professor of Electrical Engineering at AFIT, designed algorithms for MAGNAV flight testing on F-16s. Testing has already taken place using private survey aircraft.
MAGNAV sensors and software will be flown on Air Force Test Pilot School (AFTPS) F-16s over a special test range adjacent to Edwards Air Force Base in Nevada.
Magnetic anomaly navigation uses scalar magnetometer sensors that measure differences in the magnitude of magnetic fields when traveling past them. These variations can be compared with known features in magnetic field maps and be interpreted to determine position.
The four pillars of MAGNAV are magnetic maps, sensors, algorithms and calibration. The magnetic maps already exist within industry, the military and government agencies including NOAA, NASA, NGA and more.

A Loyal Wingman drone rolls out, the U.S. Air Force (USAF) sponsors air taxi-cargo UAS development, and medical deliveries take place in Scotland and Florida — we have quite a wide selection for this month’s news.
Fighter support drone

Boeing Australia has just rolled out the first “Loyal Wingman” for the RAAF (Royal Australian Air Force) — in essence what looks like a completed first article of three prototypes on order for Australia’s Loyal Wingman Advanced Development Program.
The concept is to develop an “inexpensive, expendable” UAV which will fight alongside today’s frontline fighter aircraft, controlled from the ground or from the air. A “force-multiplier” which doesn’t risk either pilot or the heap-expensive interceptor/ground attack aircraft themselves, a real bonus for smaller air-forces, and a less costly way of increasing numbers.
The first prototype will now go into a ground and flight test program to prove out systems and flight capabilities – first flight would likely be later this year.
A team of 35 Australian aerospace companies are supporting the Loyal Wingman project, including BAE Systems Australia which has been selected to supply the flight vehicle management system, flight control computers and navigation equipment.
Flying cars?
The U.S. Air Force wants a fleet of them by 2023!
So in a novel way to stir interest in the concept of flying cars, or perhaps cargo carrying drones, the Air Force launched a program known as “Agility Prime.” The program may have begun conventionally with seed contract(s) to drone manufacturers, but their latest “webcast” approach provided an extensive overview of what this could mean to the U.S. industry.
From April 27 through May 1, a panel including Air Force leaders, two U.S. Senators, NASA and Federal Aviation Administration management, and key Air Force and Defense Department players participated in an open presentation to industry, investment and State Government participants — all with the aim of accelerating civilian development of “advanced air mobility vehicles.”
Recognizing that a principle problem is overcoming regulatory hurdles, USAF intends to provide a route to commercial revenue service such as logistics transport and disaster recovery by perhaps providing access to its key testing capabilities and facilities. With broad participation in the program by industry, government and investors (i.e. USAF don’t intend to pay for it all) the program would satisfy an operational safety and security baseline and provide a platform for the “Race to Certification” of commercial drone product(s) the USAF might also want to buy.
One of the possible solutions for a cargo drone already funded includes the Sabrewing Cargo Drone – known currently as Rhaegal-A.
Four electric powered ducted fans rotate for Vertical Take-Off and Landing (VTOL) and are powered by a Safran (French) Ardiden 3 helicopter turbine engine – giving this large UAV a design speed of 245 mph, a ceiling of 20,000 feet and range of 1000 miles.
Sabrewing has received $3.25m under a two year USAF sponsored Small Business Incentive Research (SBIR) project in the hope that the design could be eventually adapted to military logistics applications. The vehicle is intended to be able to fly autonomously, has detect and avoid capability, and can even operate when GPS is continuously jammed — something the military would probably appreciate. Potential casualty evacuation is also of great interest.
Medical supplies delivery
Meanwhile in the U.K., in cooperation with the U.K. Civil Aviation Authority (CAA), Skyports drone company is playing in the CAA’s “Sandbox.” This is another term for an umbrella/sequence of trials under CAA safety and security constraints where innovative approaches are given a chance to demonstrate that new aviation related things are possible, that they actually work and that they meet the CAA criteria. Skyports wants to test out Beyond Visual Line of Sight (BVLOS) operations for its upcoming trial of medical deliveries between Oban and Mull off the West Coast of Scotland.
As front-line health professionals fight to beat the COVID-19 pandemic, deliveries of essential medical supplies between medical facilities can be speeded-up significantly using drones. Skyports will begin the week-long trial between Mull and Oban medical centers in the last week of May.
The planned BVLOS flights will be over a 17-mile route in unrestricted airspace and avoid the Oban airport, crossing the narrow sea channel and onto the North coast of the Isle of Mull. Skyports already has experience transporting medical and other high-value cargo in other parts of the world. The candidate drone is equipped with Iris Automation Casia detect-and-avoid computer vision system, and Thales Remote ID, and the Skyports drone team is also supported by Thales SOARIZON flight management and mission planning system.
Drones to deliver prescriptions
And finally, something quite helpful during the current coronavirus pandemic — CVS and UPS having linked up some time ago, are to begin delivering prescription medication to customers in Florida. The process has been previously checked out during November last year trials in Cary, N.C.
UPS will use the Swiss Matternet M2 delivery drone, picking up medication at specific CVS location(s) and flying it to a delivery point at “The Villages” in Central Florida, then the “last-mile” delivery is by road — presumably by an outfit which knows the layout of this huge facility where something like 130,000 retirees live. Useful during this phase of Florida’s self-quarantine for elders who may find it difficult to get out to the drug store. Hope they start running the same service out of my local CVS.
Wrap-up
So from the extreme military application of drone support for fighter attack missions, and USAF sponsored development of air-taxis and cargo drones, through to medical supply deliveries by drone in remote areas of Scotland and prescription deliveries in Florida — activity never seems to abate in this growing industry.
In 2019, the U.S. Air Force certified the security architecture of Raytheon Intelligence & Space’s M-code modules and receivers as providers of secure and reliable access to modernized GPS. The resilient receivers are designed for high anti-jam performance.
Raytheon’s M-code application-specific integrated circuit (ASIC) chip is either integrated into a ground-based receiver card optimized for low dynamic applications, or used as an avionics/naval receiver card to support multiple end users.
“Our focus is on taking a comprehensive approach to resilient navigation,” explained Chad Pillsbury, director for Raytheon’s Secure Sensor Solutions. “We provide the complete family of PNT solutions. We start with the fundamental components, like the ASIC chip, and tailor our solution for the platform and mission requirements.”
Open Architecture. Raytheon successfully completed testing of the first M-code receiver onboard the U.S. Air Force’s B-2 bomber in 2017. “Since then, we’ve undergone a number of tests internally and with third-parties. Our M-code receivers have standard interfaces and open architecture protocols, enabling them to work with both U.S. and allied systems. By pairing our M-code receiver with our anti-jam electronics and antenna, our systems enable warfighters to combat the most advanced threats seen in the world today,” Pilsbury said.
The receiver is planned to be incorporated into many fighters, bombers and weapons systems across the U.S. Department of Defense. “We provide enhanced anti-jam, anti-spoof GPS capabilities, as well as alternate navigation and multi-constellation support that represent a significant improvement over the systems currently used by today’s warfighters,” Pillsbury said.
Meeting Advancing Threats. “The hardest part is meeting a changing threat target,” Pillsbury explained. “The fact is the threat is advancing at a rapid rate. Because of that, challenges are constantly evolving.
“That means we had to design solutions that were simultaneously robust and secure, but also flexible and open so we can continually upgrade them. That’s not an easy thing to do.
“But, by taking a comprehensive approach that looked at the whole problem rather than just part of it, we’ve developed systems that address these challenges and have the flexibility to address future challenges.”
Raytheon’s M-code products are now available to the U.S. military and its allies in accordance with International Traffic in Arms Regulations and the U.S. State Department.
“Celebrating this anniversary gives us a moment to recognize how far we’ve come, but also to get pumped about what lies ahead for our program and our role in executing that.”
By First Lieutenant Tyler Whiting Peterson Air Force Base, Colorado
The Global Positioning System marked its 25th year of operation on April 27.
On this date in 1995, the system reached full operational capability, meaning the system met all performance requirements. U.S. Air Force Space Command formally announced the milestone three months later.
“This is a major milestone,” Gen. Thomas S. Moorman Jr., former Air Force Vice Chief of Staff, said in 1995. “GPS has become integral to our warfighters and is rapidly becoming a true utility in the civilian community.”
Initially developed for the military to meet a critical need for determining precise location on the battlefield, GPS has also become an integral part of technology affecting the lives of billions of people worldwide.
“The United States Space Force’s continuing objective for the constellation is to ensure GPS remains the Gold Standard for global space-based positioning, navigation and timing,” said Gen. Jay Raymond, USSF Chief of Space Operations, and U.S. Space Command Commander.

Today, the U.S. Space Force operates the GPS satellite constellation as a global utility – always available to everyone, everywhere on Earth.
“GPS is a free for use service provided by the Space Force that enhances everyday lives around the world,” said Brig. Gen. DeAnna Burt, USSF Director of Operations and Communications. “GPS provides the highest accuracy positioning and timing data. In addition to the essential capabilities it provides for the military, GPS underpins critical financial, transportation and agricultural infrastructure. It’s always available, whether for an ATM transaction or securing a rideshare.”
Military capabilities
Its military capabilities first enhanced combat operations in 1990 and 1991 during Operations Desert Shield and Desert Storm. Allied troops relied heavily on the new GPS signal to navigate the featureless deserts in Kuwait and Iraq.
In the early 2000s, during Operations Enduring Freedom and Iraqi Freedom, GPS contribution to warfighting increased significantly. For example, the GPS constellation enabled accurate munitions, allowing the delivery of GPS-aided Joint Direct Attack Munitions with pinpoint precision and minimal collateral damage.
Today, in addition to these and other GPS-enabled warfighting capabilities, Airmen conduct resupply missions with battlefield precision airdrops to combat forces with GPS-guided, parachute-delivered equipment pallets known as “Smart Pallets.”
Continually updated
The GPS operational constellation currently has 31 satellites, and the system is continually updated and modernized, making it a resilient system to maintain the signals required for accurate positioning, navigation and timing around the world.
The first satellite of the new GPS III version, called Vespucci, was launched into space Dec. 23, 2018.
The 2nd Space Operations Squadron at Schriever Air Force Base, Colo., operates GPS. The squadron recently accepted control of the second GPS III satellite, called Magellan, on March 27.
GPS III is meeting users’ emerging needs and responding to tomorrow’s threats with improved safety, signal integrity and accuracy. GPS III satellites are more accurate, have improved anti-jamming capabilities, and have doubled the design life; when compared to previous iterations of GPS. They are also designed to incorporate new technology and changing mission needs,
“The 25th Anniversary is a huge, momentous occasion for us. We take great pride in providing this global utility to the approximately six billion users worldwide,” said Lt. Col. Stephen Toth, 2nd SOPS commander. “Celebrating this anniversary gives us a moment to recognize how far we’ve come, but also to get pumped about what lies ahead for our program and our role in executing that.”
On March 23, the U.S. Space Force’s Space and Missile Systems Center successfully transferred the second GPS III space vehicle (GPS III SV02) to Space Operations Command.
GPS III SV02, dubbed “Magellan” in honor of Ferdinand Magellan, the Portuguese explorer who led the first expedition to circumnavigate the Earth, is now officially under the control of the Second Space Operations Squadron located at Schriever Air Force Base, Colorado.
GPS III SV02 was launched on August 22, 2019, aboard a United Launch Alliance Delta IV Medium+ launch vehicle from Cape Canaveral Air Force Station, Florida.
GPS III satellites deliver positioning, navigation and timing information with three times better accuracy, and up to eight times improved anti-jamming capability than its predecessor. This is crucial for the warfighter, who will benefit from the increased power, accuracy and protections provided by the newer GPS III systems.
“This marks our second transfer of Satellite Control Authority for the GPS III program as we continue to modernize the GPS constellation with more capable and resilient systems,” said Col. Edward Byrne, chief of Production Corps’ Medium Earth Orbit Space Systems Division. “It’s only through the hard work, professionalism, and dedication of our entire government and industry partner team that we can successfully transition GPS III SV02 to operations.”
The GPS III spacecraft has a 15-year design life, 25 percent longer than the last generation of GPS satellites currently on-orbit. Additionally, it delivers new capabilities, such as a fourth civilian signal (L1C), designed to enable interoperability between GPS and international satellite navigation systems, such as Galileo. GPS III satellites will also bring the full capability of the military code (M-code) signal, increasing anti-jam resiliency in support of the warfighter.
These continued improvements and advancements to the GPS system make it the premier space-based provider of positioning, navigation, and timing services for more than four billion users around the globe.
U.S. Space Force’s Space and Missile Systems Center, located at Los Angeles Air Force Base in El Segundo, California, is the U.S. Air Force’s Center of Excellence for acquiring and developing military space systems. Its portfolio includes the Global Positioning System, military satellite communications, defense meteorological satellites, space launch, range systems, satellite control networks, space-based infrared systems and space situational awareness capabilities.
The U.S. Air Force is using a digital replica of a GPS IIR satellite to detect any cyber-security issues, reports Air Force Magazine.
Booz Allen Hamilton created the “digital twin” of the Lockheed Martin-built Block IIR GPS satellite — and then tried to hack the system.
“The satellite itself was on orbit,” BAH Vice President Kevin Coggins told Air Force Magazine. “So we built this digital model … and then we went looking for vulnerabilities. We did [penetration] testing and we saw what we could discover.”
The project is in response to a congressional mandate to test GPS for cyber vulnerabilities. Testing areas include the satellite, ground control stations and the radio-frequency links between them. BAH then conducted “man-in-the-middle” attacks on the communication links to identify potential weaknesses between the satellite and its ground control station.
The 12 Block IIR legacy satellites, launched between 1997-2004, were designed for a 7.5 year lifespan, but it will be years before they can be decommissioned.

The U.S. Air Force is expected to take delivery of more than 100 D2 Charlie aviator watches for the specialized pilot group that flies the Lockheed U-2 aircraft.
Garmin’s D2 Charlie aviator watch has been selected by the United States Air Force (USAF) for use by the pilots of the Lockheed U-2 aircraft.
The high-sensitivity WAAS GPS-enabled D2 Charlie aviator watch incorporates global navigation capability, rich and colorful moving maps and more, providing pilots in the USAF with an exclusive, back-up navigation timepiece in the cockpit.
The watch receives both GPS and GLONASS signals.
U-2 for reconnaissance. The U-2 is a versatile, ultra-high-altitude reconnaissance aircraft used for intelligence gathering, research and communication purposes.
The U-2 provides high-altitude, all-weather surveillance and reconnaissance, day or night, in direct support of U.S. and allied forces. It delivers critical imagery and signals intelligence to decision makers throughout all phases of conflict, including peacetime indications and warnings, low-intensity conflict, and large-scale hostilities.
100 watches ordered. The USAF is expected to take delivery of more than 100 D2 Charlie aviator watches for the specialized pilot group that flies the Lockheed U-2 aircraft. With a service ceiling of 70,000 feet, the D2 Charlie will provide unique benefits such as barometric-based O2 alerting and GPS-specific features including track, distance to the next waypoint, estimated time enroute and more.
“Garmin is honored to have been selected by the United States Air Force to equip the men and women who fly one of the most iconic aircraft in the history of aviation,” said Carl Wolf, Garmin vice president of aviation sales and marketing. “The D2 Charlie aviator watch will be an integral and functional part of the U-2 pilot’s toolkit.”
