  • Russia’s space-based nuclear weapon? Here’s an educated guess

    Russia’s space-based nuclear weapon? Here’s an educated guess

    Earlier this week House Intelligence Committee Chair Mike Turner sounded an alarm about a serious national security threat. It had to do with Russia, a weapon, space, and something nuclear.

    For many, these clues conjured up images of bombs falling to Earth from space, satellites destroyed by powerful electromagnetic pulses, shrapnel impacting the space station, and so on.

    Yet, putting nuclear weapons in space would be a clear violation of the 1967 Outer Space Treaty to which Russia and the United States are both signatories. It would also significantly increase East-West tensions at a time when Russia has enough tension and international condemnation to handle.

    Thursday evening the White House calmed the waters a bit by saying that Russia was pursing an anti-satellite weapon that cannot cause physical destruction on Earth.

    The most reasonable conclusion to draw from all of this is that Russia is closing in on its goal of having a nuclear-powered electronic warfare capability in space.

    Such a reusable weapon could be far more useful than any one-use nuclear explosive device.

    Threat = Intent + Capability

    A lengthy and detailed 2019 article on the site “Space Review” examined indications that Russia had begun construction of such a device. Titled “Ekipazh: Russia’s top-secret nuclear-powered satellite” it begins:

    “There is strong evidence from publicly available sources that a Russian company called KB Arsenal is working on a new type of military satellite equipped with a nuclear power source. Called Ekipazh, its mission may well be to perform electronic warfare [EW] from space.”

    The author, Bart Hendrickx, goes on to explain that development of such a weapon would be entirely in keeping with reported Russian government plans. Citing one Russian language source he says:

    “… the deployment of EW platforms in orbit would be in accordance with a policy for Russia’s electronic warfare program until 2020 approved by the Russian government in January 2012. A summary of this policy indeed mentions space-based electronic warfare as one of the objectives to be accomplished in the period before 2025. More specifically, it talks about the need to deploy ‘multifunctional space-based EW complexes for reconnaissance and suppression of radio-electronic systems used by radar, navigation and communications systems.’”

    When intelligence agencies assess the severity of a particular threat, they look at an adversary’s desire or intent to carry out a particular act, and their capability to do so. If the reporting is correct, Russia has intended to put a nuclear-powered EW satellite or spacecraft in orbit for some time. This week’s political dust up may mean that the decades of hard work described by Hendrickx in Space Review have paid off and given them the ability to do so.

    More Useful Than Orbiting Bombs

    The United States is far more dependent upon space than any other nation. As regular GPS World readers know, this is especially true for the essential positioning, navigation, and timing services that underpin virtually every technology.

    Destroying satellites would quickly lead to a shooting war that no one would want.

    On the other hand, electronic warfare doesn’t necessarily lead to casualties right away and is harder to recognize as actual warfare. For example, Russia has been attacking NATO countries, ships, and aircraft in the Baltic with GPS jamming and spoofing on and off since mid-December. No one has died (yet) and NATO, to the best of our knowledge, has not responded.

    Rather than destroying satellites, how much more useful is it to be able to temporarily disrupt the operation of one or more satellites? Or perhaps one type of satellite, such as GPS?

    Such attacks are reversable, so the attacked party is less likely to send bombs and bullets in return right away. And if the attacker gets what they want, or suddenly discovers they have gone a bit too far and are approaching a kinetic exchange, backing off is as easy as flipping a switch.

    Just the threat of being able to deny GPS or other satellite signals over a wide area would be useful.

    In fact, Russia has already made this kind of threat and it didn’t backfire.

    In November 2021, prior to its invasion of Ukraine, Russia used a ground-based missile to destroy one of its own defunct satellites. Shortly thereafter Russian state-sponsored media claimed the demonstration “… means that if NATO crosses our red line, it risks losing all 32 of its GPS satellites at once.” Aside from a strong diplomatic tongue-lashing, there were few consequences. Additionally, wherever the “red line” was, it seems that NATO did not cross it.

    Nuclear Powered EW Most Likely

    It’s hard to know what more will be revealed, if anything, about this week’s dust-up over Russia, weapons, space, and nuclear.

    But Russia has long prided itself on its electronic warfare prowess. It sees EW as a counterbalance to the West’s dominance in high tech weapons and warfare.

    It is highly likely that Russia is executing its plans to extend this prowess and advantage into space with a nuclear-powered EW satellite.

    Whether or not this is the root Washington’s kerfuffle, the possibility should be an on-going concern for the United States.

    Our dependance on space makes us vulnerable. Our critical over-dependence on space for PNT, especially in light of the terrestrial PNT alternatives available to Russia and China, exposes our jugular and virtually invites attack.

    We have placed most of our eggs in the same basket — and there are too many ways in which it can be knocked to the ground.

    Until the United States establishes a resilient national PNT architecture, one with GPS at its center supported by other diverse and robust sources, we will continue to unintentionally encourage such things as space-based nuclear-powered electronic warfare and be at severe risk.

    The Turkish Armed Forces have added the BAHA autonomous sub-cloud UAV to their reconnaissance capabilities. The UAV can be used for tracking, detection, area protection, intelligence and electronic warfare.

    The BAHA, developed by Turkish defense company HAVELSAN, is an independent sub-cloud UAV equipped with vertical take-off and landing (VTOL) capabilities. It has complete autonomy in mission execution and allows for the integration of diverse payloads.

    With the ability to execute missions at altitudes of up to 15,000 feet, the BAHA has a maximum flight duration of six hours with a gas engine and covers a range of up to 80 kilometers. It also features a 5-kilogram payload capacity and a 3.7-meter wingspan. The system, designed for quick deployment by two individuals and operation by a single person, can be mission-ready within minutes, according to HAVELSAN.

    Tested in various regions, challenging climates, and operational conditions, the system has been improved based on feedback from security forces.
    HAVELSAN has achieved export success with the BAHA in Africa and Central Asia this year. After successful tests, it is now available for domestic use by security forces.

    Beyond the frontlines: The far-reaching effects of electronic warfare

    Electronic warfare in the Middle East and Ukraine is affecting air travel far beyond the battlefields, unnerving pilots and revealing unintended consequences of a tactic that experts believe will become more widespread, reported The New York Times 

    Planes are losing satellite signals, flights have been diverted and pilots have received false location reports or inaccurate warnings that they were flying close to terrain, according to European Union safety regulators and an internal airline memo viewed by The New York Times. The Federal Aviation Administration (FAA) has also warned pilots about GPS jamming in the Middle East. 

    Following Russia’s invasion of Ukraine in early 2022, radio frequency interference only continues to increase across the Middle East as of autumn 2023. These interferences can involve jamming GNSS signals to obstruct or block them using noise, or mimicking signals to trick GNSS receivers into picking up counterfeit satellite signals, known as spoofing.  

    Aircraft systems have been unable to detect GPS spoofing and ultimately correct for it. According to Opsgroup, an organization that monitors changes and risks in the aviation industry, one Embraer jet bound for Dubai nearly veered into Iranian airspace in September before the pilots figured out the plane was chasing a false signal. 

    “We only realized there was an issue because the autopilot started turning to the left and right, so it was obvious that something was wrong,” crew members reported to Opsgroup. 

    Issues arise 

    With the rise of electronic warfare, the strain on aviation could be a sign of more serious economic and security issues.  

    The U.S. government calls GNSS signals “an invisible utility.” Smartphones, cars, stock exchanges, data centers and countless industries rely on them for time, navigation or both. Similar systems exist around the world, such as Galileo in Europe, Glonass in Russia, QZSS in Japan, NavIC in India and BeiDou in China. One study from Britain said a five-day disruption of satellite signals could cost the country $6.3 billion. 

    Minor interference with GPS signals is fairly common. GPS jamming devices, while illegal to use, are inexpensive and easy to obtain from vendors on the internet. Governments, too, have been more willing to overtly interfere with signals as a tactic in electronic warfare. 

    It is not always possible to distinguish jamming from spoofing, or to determine who is behind the interference. Israel said in mid-October it had restricted GPS in the region and had warned pilots not to rely on satellite navigation systems for landing.  

    Russian interference is well-documented. A 2019 report by the Washington-based analytical nonprofit group C4ADS showed extensive spoofing from a Russian-controlled air base in Syria. Reports also indicated that, when Russian President, Vladimir Putin, traveled to remote locations or Russian-occupied Crimea, he was flanked by mobile GPS-spoofing technology. 

    Russia has disrupted GPS signals to misdirect Ukrainian UAVs and throw precision-guided shells off their targets. Ukraine also jams Russian receivers but lacks the same level of sophistication 

    Jamming is common in conflict zones. Spoofing, until recently, was considered rare.   

    The interference has been felt up to 190 miles away from battlefields and “appears to go well beyond simple military mission effectiveness,” according to Eurocontrol, Europe’s primary air-traffic-control manager. The worst-affected regions include the aerial space above the Black Sea area from Turkey to Azerbaijan; the Mediterranean Sea extending from Cyprus to Libya; the Baltic Sea near Poland and Latvia; and the Arctic near Finland and Norway. 

    Airbus said it recorded nearly 50,000 interference events on its aircraft last year, more than four times as many as the year before. This came on top of an over twentyfold jump in radio-interference events from 2017 to 2018, as recorded by a voluntary incident reporting system run by Eurocontrol. Eurocontrol said the increased jamming since 2018 was most likely meant to interfere with battlefield UAVs. 

    In the Middle East, there have been reports of false signals telling pilots their aircraft were directly above the airport in Tel Aviv despite being far away. Opsgroup said it had received around 50 similar reports. In some cases, onboard equipment showed that planes were approaching airports in Baghdad, Cairo or Beirut, Lebanon, when they were not. 

    Looking ahead 

    Spoofing is hard to distinguish because the signal appears legitimate. Only Europe’s Galileo incorporates an authentication system that can verify when a signal is from its satellites. Galileo, which currently is the most accurate and precise navigation satellite system, plans to introduce an even stronger level of authentication, according to the European Commission. 

    But even Galileo’s authentication cannot protect against one of the most dreaded types of spoofing, known as “meaconing.” In a meaconing attack, a spoofer would record satellite signals, and then rebroadcast them with an amplification or a delay. Experts have not publicly confirmed any meaconing attacks in the Middle East. 

    Opsgroup said the latest events should prompt manufacturers to re-examine the integration of satellite signals in aircraft electronics, known as avionics, without a safeguard that can identify false signals.

    In this environment of intentional GPS jamming and spoofing, Israel has produced a leading anti-jam technology company, InfiniDome, located in Caesarea. According to co-founder Omer Sharar, the company has been working to defend GPS signals for more than seven years and has also seen the rise of devices to jam the GPS L1 frequency that anyone can buy online for $100.   

    Gpsdome-1 (left) protects GPS L1. GPSdome-2 (right) protects GPS L1/L2 or GPS L1/GLONASS L1.

    Most readily available jammer electronics only output interference disrupting GPS L1, which is commonly installed for vehicle tracking and UAV guidance. InfiniDome says it has successfully protected trucking, UAV operations and others in Israel and around the world with its Infinidome GPSdome-1 and GPSdome-2 anti-jam products. 

    It is clear the conflict’s repercussions extend well beyond the battlefield, highlighting the critical need for security assessments or alternative PNT systems to protect civilians. While there is going to be a significant impact on commercial airline travel to and from Israel while hostilities continue, there is hope for a possible long-term solution for the intense jamming that has plagued the region for years.

    We asked Dean Kemp, Ph.D., director of Marketing, Aerospace and Defense for Hexagon’s Autonomy & Positioning division, a few questions.

    How do jamming and spoofing threats change?

    Jamming and spoofing methods change as new interference-causing technologies become available. As such, it’s vital for us to continuously evaluate potential sources of threats and provide the highest possible level of resiliency to interference in our solutions.

    Have new threats emerged in the past six weeks in connection with Russia’s invasion of Ukraine?

    Evidence is emerging that electronic-warfare systems capable of high-power jamming and spoofing across wide areas are being used within Ukraine. Fortunately, there have been no known impacts on allied forces. However, knowing that the technology is in place and in use highlights the importance of assured positioning, navigation and timing (APNT) and our contribution to building resiliency in allied forces’ equipment against the potentially destabilizing effects of jamming and spoofing.

    How do you define APNT?

    We use APNT to describe measurements that are always accurate, available and reliable. Our anti-jamming, anti-spoofing and other resilience-building capabilities provide trusted and available PNT information at the level of accuracy requested.

    When did you introduce GPS Anti-Jam Technology (GAJT)? How do you define it?

    GAJT was introduced in 2011 and is our leading APNT solution. GAJT units are utilized worldwide across land, sea and air, with rapid deployment supported by commercial off-the-shelf solutions and short lead times. GAJT provides jamming protection of satellite-based navigation and precise timing receivers from intentional jamming and unintentional interference whatever your application. Product variants provide features to best support anti-jamming capabilities for the warfighter, national infrastructure, low-SWaP platforms and other mission-critical applications.

    What are the key differences between the GAJT-710ML, the GAJT-710MS and the GAJT-410MS?

    The GAJT-710 is designed for land vehicles (ML variant) and marine vessel platforms (MS variant) with up to six simultaneous nulls to protect against jamming signals and interference. The next generation of GAJT-710 includes jammer direction-finding and a silent mode to reduce its thermal signature. The GAJT-410 maintains the high levels of interference-rejection performance in the 710 but in a lower size, weight and power (SWaP) design, with three simultaneous nulls, for both land and marine variants. It also utilizes a single RF cable to provide clean power, data and protected GPS signal. The GAJT-410 enables APNT while also reducing the need for platform modifications or armor penetration.

    The GAJT-AE extends jamming and interference protection to unmanned and autonomous applications. Using an external CRPA antenna, the GAJT-AE offers flexibility of integration into space-constrained platforms.

    Is the GAJT-AE-N Anti-Jam Antenna receiver-agnostic?

    We designed our GAJT product line to be receiver-agnostic and compatible with legacy and modern GNSS receivers. This flexibility results in GAJT being ideal for civil and military applications, including SAASM and M-code systems.

    How does your GNSS Resilience and Integrity Technology (GRIT, launched in 2020 November) relate to your GAJT antennas?

    GRIT is a firmware suite for our OEM7 receivers that expands their situational awareness and interference mitigation tools. GRIT includes our Interference Toolkit (ITK) along with spoofing detection to identify when your GNSS signal may be under threat. It also empowers the user to develop interference location algorithms through time-tagged snapshots of data samples to characterize the RF environment around your operations. GRIT, alongside GAJT, forms the foundation of our APNT strategy in providing accurate and always-available PNT.

    Do you have any recent contracts with the U.S. Department of Defense or the militaries of other NATO countries to supply GAJT antennas?

    Our GAJT product portfolio has been sold in large quantities to military and civil organizations for many years, successfully proving itself in the field. In 2020, we achieved a milestone of more than several thousand units shipped worldwide, making it one of Hexagon | NovAtel’s more successful years.

    An expert has warned the government of the United Kingdom that the lack of an alternative to Galileo threatens to put critical infrastructure at risk, according to a report in Daily Express.

    Andy Proctor, formerly with the satellite and positioning, navigation and timing (PNT) cabinet office, submitted evidence of his concerns to the UK’s ministers.

    “Our critical infrastructure is at risk from the loss of PNT, space-based or otherwise,” he wrote. “We are currently critically dependent upon GPS; the loss of which will have a major impact in capability and economically.”

    Proctor is director of Rethink PNT, a consultancy firm.

    He pointed out that the government disinvested in the eLoran terrestrial system that could have provided a backup, although this is slowly reversing.

    “For 20 or so years there have been calls for action, yet the current status of inaction regarding the PNT strategy puts our systems at increasing risk, especially given the clear and present electronic-warfare systems being used in Europe today,” Proctor wrote.

    Britain was removed from the Galileo project following Brexit, and has since been looking for an alternative PNT system.

    CMOSS prescribes criteria for integrators that reduce the size, weight, and power (SWaP) of C5ISR and EW systems while increasing their flexibility and adaptability by enabling the sharing of hardware and software components.

    Orolia submitted a CMOSS timing card and was formally recognized as a top five winner at OIL’s open house (with 200+ attendees) for demonstrating its capabilities and commitment to supporting the U.S. Army and DOD in pursuit of CMOSS PNT solutions.

    “I am extremely proud of our team for their efforts and sharp-wittedness in developing and presenting this technology at an accelerated level,” said Conrad Meyer, director of business development at Orolia Defense & Security. “We are honored to have taken part in this event and to be distinguished among many contenders.”

    Orolia’s prototype has a plug-and-play architecture powered by its FlexFusion engine, with additional capability for jamming and spoofing detection via its patented BroadShield software. It is designed for easy in-field upgradability.

    Orolia plans this year to release a commercially available, fully compliant CMOSS/SOSA PNT card for use in military air and ground-mounted systems.

    TRX Systems, developer of NEON GPS-denied location solutions, has been selected by the U.S. Army to provide a next-generation Dismounted Assured Positioning, Navigation and Timing (PNT) System (DAPS).

    The TRX DAPS solution employs a lightweight soldier-worn device that enables dismounted warfighters to successfully conduct operations when operating in GPS challenged, degraded or denied environments.

    Military equipment can be the subject of enemy electronic attacks, potentially resulting in a loss of location awareness that can put army missions at increased risk. The TRX DAPS solution alerts the users when their position isn’t reliable and then leverages multiple sensors and timing sources to provide the best soldier position possible within the GPS-degraded operational environment.

    The solution — designed to replace the Defense Advanced GPS Receiver (DAGR) — supports both a standalone configuration and integration with the Nett Warrior ensemble. It combines inputs from small, body-worn sensors and other sources to provide assured PNT while meeting the size, weight and power (SWaP) needs of dismounted soldiers already physically burdened with heavy equipment loads.

    TRX Systems has delivered GPS-denied location technology to thousands of military, public safety  and security users worldwide.

    “Maintaining assured PNT is paramount to the situational awareness of U.S. warfighters in the many conflict zones around the world,” said Carol Politi, president and CEO of TRX Systems. “When initial units are fielded in mid-2022, the TRX DAPS solution will deliver a balance of the highest possible level of integrated PNT capabilities with the smallest package that can be fielded for dismounted warfighters.”

    Thales and CS Group partner to offer navies a cybersecure, jam-resistant navigation system inspired by civil aviation

    Thales and CS Group have partnered to offer a complete navigation system for navy surface ships. At the heart of the system is the Thales TopAxyz inertial navigation unit, which is integrated with CS Group’s real-time computer to combine high-level performance and resilience in an electronic warfare environment. The system provides high-precision pointing, gyrocompass, location and navigation functionality for all types of naval platforms, from surface combatants and submarines to autonomous vehicles.

    The TopAxyz inertial navigation unit has delivered outstanding performance in the rigorous conditions of civil aviation, clocking more than 20 million hours of operation. The naval version of the unit was integrated on a French Navy vessel in less than a day by CS Group, and has already proven its operational value for maritime navigation in a sea trial.

    “After proving their value on board aircraft, space launchers and French Army land vehicles, Thales inertial navigation systems are now available for naval platforms,” said Tristan Grivel, vice president business development and sales for Thales’s flight avionics business.

    “CS Group has supplied real-time navigation computers, military-grade GPS receivers and other solutions to the French Navy and Naval Group for many years, explained Gilles Rigal, director of CS GROUP’s naval systems business line. “This partnership with Thales allows us to offer an innovative, robust and resilient maritime inertial navigation system for surface ships,” Rigal said.

    Countering electronic warfare

    In today’s constantly changing naval environment, crews need to contend with the threat of cyberattacks, electronic warfare activity and the high risk of jamming and spoofing of GPS-based radionavigation solutions. Accurate navigation data, real-time data distribution and resistance to external threats are crucial for every mission conducted by a naval vessel today.

    Thales and CS Group have worked together for more than 20 years to address these issues. Drawing on their combined expertise across all the key navigation system technologies, the two companies are now proposing a new approach to maritime navigation based on more trustworthy and reliable navigation data.

    The TopAxyz inertial unit uses accurate, reliable navigation information that is independent of sea state and vessel location, combined with a function that detects attempts to spoof GPS signals. The navigation data calculated by TopAxyz is distributed in real time by the NDDS (Navigation Data Distribution System) developed by CS Group’s onboard computer.

    The computer uses the latest technological advances in cybersecurity, guaranteeing the best level of resilience to attacks. Its architecture offers three key advantages: safer navigation, reduced costs and integration risks, ease of use and simplified maintenance of the system. No calibration is required during the service life of the system, reducing the total cost of ownership.

    The new maritime navigation system are now available, and are being manufactured at the companies’ production and integration facilities in Châtellerault and Aix-en-Provence in France.

    Electronic Warfare Kit enables dismounted soldiers to detect, map and mitigate the impact of navigational warfare (NAVWAR) attacks

    TRX Systems, developer of NEON GPS-denied location solutions, has delivered the TRX Systems Dismount Electronic Warfare (EW) Kit prototype to the U.S. Army.

    Developed for U.S. Army Rapid Capabilities and Critical Technologies Office (RCCTO), the TRX EW Kit is designed to extend EW and signal intelligence for the dismounted warfighter.

    The kit adds powerful new capabilities to the company’s NEON Personnel Tracker-MIL solution, expanding the integration between its NEON Location Service and ATAK application to better equip dismounted personnel for detection and mapping of jamming and spoofing attacks.

    New NEON functionality includes:

    • Robust Interference Detection. Rapidly detects and geo-references NAVWAR threats including GPS jamming, repeating and spoofing.
    • NAVWAR Threat Mapping. Increases situational awareness by geo-referencing and mapping detected threats through integration with ATAK and EW platforms.
    • Reliable Dismount Location Data. Mitigates the impact of NAVWAR attacks by eliminating erroneous GPS inputs while continuing to deliver reliable location data to dismounted users.
    • Integration with NAVWAR Devices. Integrates threat data from Orolia Defense & Security BroadSense Nano and other devices already carried by warfighters to provide a fused NAVWAR threat indication.

    The NEON Personnel Tracker Military (PT-MIL) uses a suite of patented algorithms that fuse GNSS, an inertial sensor, ultra-wideband (UWB) and other inputs to deliver reliable position data to dismounted personnel operating in the presence of compromised or intentionally denied GNSS signals.

    With the new EW Kit functionality, warfighters will receive real-time situational awareness into jamming or spoofing threats at their immediate location and from other dismount personnel sharing data over the TAK network.

    The EW Kit is integrated via soldier plug-ins, enabling threats discovered and mapped by dismounts to be fused into the overall NAVWAR threat picture.

    “In today’s conflict zones, it’s becoming increasingly easy for adversaries to launch electronic attacks against GNSS systems using low-cost jammers built with readily available commercial technology,” said Carol Politi, president and CEO of TRX Systems. “The EW Kit developed in the RCCTO program provides dismount soldiers with clear insight into their NAVWAR environment by rapidly detecting and characterizing these NAVWAR attacks, and it mitigates the impact by eliminating compromised data from their position solution.”

  • British Army Light Dragoons demo anti-jam technology

    British Army Light Dragoons demo anti-jam technology

    NATO forces are deployed in some of the world’s most aggressive electronic-warfare (EW) environments. Intentional interference comes both from “personal protection” devices and large, high-powered EW assets.

    To navigate despite EW, armed forces need reliable and resilient GNSS/GPS positioning with anti-jam technology. The Light Dragoons — a light cavalry regiment of the British Army — are in a perfect position to test anti-jam technology for assured positioning, navigation and timing (A-PNT).

    The Light Dragoons were deployed as the United Kingdom’s Light Cavalry contribution to “Battlegroup Poland,” part of NATO’s enhanced Forward Presence. On the front line, the Light Cavalry engage in reconnaissance, mark targets for indirect fires, and prepare routes for the rest of the force. In this role, being prepared for EW is essential.

    To test A-PNT technologies, the Light Cavalry took part in Project Thundercat, a light cavalry capability investigation run by the Armoured Trials and Development Unit (ATDU). A Hexagon | NovAtel GPS anti-jam technology (GAJT) antenna, the GAJT-410ML, was fitted to a Jackal high-mobility transporter and integrated with its onboard positioning system.

    GAJT successfully defeats jamming on GPS L1 and L2 and Galileo E1 frequencies. When interference is detected, GAJT recognizes the unwanted interference and reduces reception in that direction. The result is a more resilient GNSS solution, protected measurements and A-PNT.

    The Light Dragoons found that GAJT successfully protected their positioning system despite experiencing interference. The GAJT-410ML antenna was easy to install in a simple plug-in-and-go process.

    In upcoming experiments, the British Army will use NovAtel technology to gain electronic situational-awareness data to characterize the radio frequency environment.

    GAJT systems are offered by NovAtel with customized offerings for land, marine and air applications.

    A new combination master clock and GPS-aided inertial navigation system is now available from Spectracom to reduce redundant subsystems in mobile applications. The Geo-PNT integrates precision references for position, attitude, and timing all in one box. Applications include radar, optoelectronic sensing, electronic warfare, satcom on the move, and mobile test platforms.

    Geo-PNT benefits any mobile intelligence, surveillance, and reconnaissance (ISR) platform because signal/electronic intelligence applications require precision positioning, navigation, and timing references. Electro-optic sensors and other imaging technologies, antenna steering, and encrypted communications always need a combination of precision motion compensation, geolocation, time stamping, and frequency reference.

    The high degree of integration within the Geo-PNT supports the goals of low size, weight and power (SWaP) and cost optimization while achieving a high level of performance for ISR platforms and mobile communications systems. A single subsystem for all PNT functions in a volume of about 40 cubic inches is about three times less than the traditional approach of deploying dedicated devices.

    The Geo-PNT is a highly configurable platform to provide the capabilities needed for the mission:

    • Single-box solution combining precision local oscillator, inertial motion unit (IMU), and GPS receiver.
    • Configurable output interfaces for timing and navigation.
    • Standalone or RTK/differential GPS, commercial (non-ITAR) or SAASM GPS receiver.
    • Choose from a variety of IMUs to meet performance specifications.
    • NTP server, precision 1PPS, 10 MHz with low phase noise.
    • Rugged and tested to MIL-STD-810G.
    • Low SWaP (< 0.7 liters, <0.8 Kg, <10 watts).

    “Our time and frequency technology, combined with geodetics positioning and navigation capability in the same module, provides an opportunity for platform designers to lower SWaP requirements while staying within the limits of today’s demanding system specifications,” said Rohit Braggs, Spectracom’s sales and marketing VP.

    Geo-PNT is the latest example of Spectracom’s flexible configure-to-COTS approach. The use of commercial technology reduces lead time and offers the lowest cost of ownership for both standard and semi-custom configurations. Hardware and software can be adapted to meet the needs of the application.
