A demonstration airspace management system is playing a role during the military exercise Rim of the Pacific (RIMPAC) 2022, taking place in Hawaii and Southern California.
FlightHorizon COMMANDER, provided by Vigilant Aerospace to the U.S. Air Force, is an airspace management and detect-and-avoid system based on two licensed NASA patents. The system can be used on the ground or onboard aircraft and is designed to help keep unmanned aircraft systems (UAS or drones) safe and collision free.
For the first time, U.S. Air Force MQ-9 UAS — also known as a Reaper — is taking part in a RIMPAC exercise. RIMPAC is the world’s largest international maritime exercise, involving more than 40 ships, 30 UAS and 150 aircraft from 27 partner nations.
RIMPAC 2022 is the 28th exercise in the series that began in 1971. The 2022 exercise takes place from late June to early August.

FlightHorizon COMMANDER includes a 3D moving map display for air traffic situational awareness, air navigation charts, weather data, special features for the tracking and safety of uncrewed aircraft systems (UAS) and automatic detect-and-avoid functions.
The airspace management system correlates and displays air traffic and other data from a wide variety of sources including ground-based and airborne sensors, civilian air traffic data, military data and proprietary data sources. The dual-use technology provides automatic traffic warnings and deconfliction as a built-in function.
The product is based on two licensed NASA patents and has been used in ongoing NASA supersonic projects, in FAA detect-and-avoid projects, and in civilian UAS projects around flight corridors and drone ports.
“RIMPAC 2022 marks the first appearance of the MQ-9A Reaper, a remotely piloted aircraft, and its presence brought in military teams from California, New Mexico and Nevada,” the Air Force stated. “With personnel from both the active-duty element, Reserves and Air National Guard, the collective group ensures that it is fully operational. All the while, everyone learns new techniques that it will take to improve their day-to-day operations upon returning home.”
“Vigilant Aerospace is thrilled to support this large-scale exercise,” said Kraettli L. Epperson, CEO of Vigilant Aerospace. “Support of this exercise is an especially useful demonstration of the multi-sensor and multi-data source capabilities of FlightHorizon and the ability to track hundreds of targets simultaneously.”
Vigilant Aerospace holds a U.S. Department of Defense IDIQ to support military adoption of the system for UAS and airspace safety.
Last month we attempted to provide an overview of the issue concerning Federal Communication Commission’s (FCC) licensing of C-Band radio spectrum, the subsequent fielding of wireless service for 5G phones and the Federal Aviation Administration’s (FAA) announcements that potential interference could be possible between 5G signals and C-Band radio altimeters on commercial aircraft.
Not a big deal most people might say, as faster and improved phone and data messaging on their smartphones begins to kick in, while wireless companies continue roll-out of the new 5G service. But wait – don’t some of these people fly out on vacation and then back and land at local airports, and many of us fly around the US to visit friends and family, or each week shuttle around the country doing fly-in/fly-out business?
Well FAA and the wireless companies have largely collaborated during 5G service roll-out, and the FAA has been rapidly clearing a good number of rad-alt (radio altimeter) equipped aircraft to continue regular operations into most airports. And it seems that wireless companies have limited 5G fielding around some US airports by reducing transmitted power and/or limiting the density of 5G towers.
But where are we now? Seems some aircraft equipped with some types of rad-alt can fly into some airports – the FAA published a list for aircraft operators and pilots identifying who can do what and where. They also published several ADs (Airworthiness Directives) which limit several aircraft types from flying into certain airports, ‘prohibiting certain operations, which require radioaltimeter data to land in low visibility conditions, when in the presence of 5G C-Band interference’. For any aircraft passengers flying into LaGuardia on a foggy day or Boston when ice-fog hangs in the air – low visibility landing capability on modern aircraft is a blessing and a wonder which allows us to travel, even in bad conditions.
Seems that, typically – ‘many systems on (XY Type) aircraft rely on the radio altimeter, including autothrottle, ground proximity warning, thrust reversers and Traffic Collision Avoidance System,’ says one recent FAA AD.
That’s a whole bunch of critical systems which help an aircraft land. Many experts over many years have spent whole careers supporting the process of developing safety systems for auto-land and those which assist in the manual landing of aircraft. And the FAA and other agencies around the world have made every manufacturer prove and prove again that these systems work and work extremely, reliably, well.
Not that I’m against 5G – I have a 5G phone and I’m eagerly waiting for 5G applications to use on my phone. – the service seems to be very fast when in an area where 5G has been fielded. There are some wireless companies who have decided that 5G can by-pass cable in the distribution of TV channels – this is good stuff! Let’s have more of it!
But why on earth do we need to even partially compromise any aircraft systems which safely land aircraft?
Japan and France have been cited as counties in which 5G has not had any impact on the very same aircraft and their operations with which the FAA has found problems. Well, except those countries seem to have taken steps in the fielding of 5G which have protected their aircraft operations. The FAA quotes several mitigations used in those countries:
• Lower power levels
• Antennas adjusted to reduce potential interference to flights
• Different placement of antennas relative to airfields
• Frequencies with a different proximity to frequencies used by aviation equipment
Let’s hope that FAA’s intense efforts to test and clear rad-alts under the simulated intensity of C-Band interference around airports will continue unabated and that soon we aviation nuts will begin to breath more easily.
And let’s hope that the wireless companies cooperation, acceptance and mitigation steps – for which the whole aviation community is extremely grateful – that these very positive steps will directly lead to the whole issue fading away over time as old news.
And then a few words about ‘the war‘ which Russia just began against its neighbor and previous member of the USSR – Ukraine has been independent from Russia since the USSR ‘dissolved’ (Wikipedia) in 1991.
Ukrainians are pretty resilient and the news today is that a woman in Kyiv brought down a Russian drone by throwing a jar of pickles at it from her (high-rise?) balcony. This story of course isn’t verified, but it’s a small lightness in a very grim situation.

And its reported that Poland just placed an urgent operational requirement for armed MQ-9 Reapers in order to better protect its Eastern border with Ukraine. The border is around 530 miles long and is the main crossing point for the thousands of refugees fleeing the Russian onslaught. Poland has apparently already taken in almost a million people seeking safety.
Drones are now part of modern warfare and both East and West have pretty sophisticated, capable, weapon-carrying unmanned aircraft. But they also usually carry highly accurate satellite navigation and laser-guided weapons which may minimize unintended casualties – unless casualties are exactly what the Russians are after.
Really sad state of affairs which we all may still follow in detail through news reports, even though Russia has completely shut down social media and virtually outlawed on-the-ground news reporting.
After a couple of good hours of progress, we suddenly ran up against a massive “tail-back” — as the English call road-blocks — on the A303. We eventually crawled along further and discovered that all the rubber-neckers were slowing to grab a glimpse of Stonehenge, which you can see on the left, not far from the road. A little further on I saw a sign for Farnborough and thought that its surely around this time of year for that huge aerospace show known as the Farnborough International Airshow. So when I arrived home after almost three email-less weeks, it was not surprising that my inbox was crammed with lots of European aerospace news.
SkyGuardian MQ-9B
General Atomics (GA-ASI) seems to have come out tops in UAV public relations, flying its MQ-9B company-owned SkyGuardian from Grand Forks, North Dakota, to Royal Air Force (RAF) Fairford in Gloucestershire, U.K. on July 10-11 — that’s a 3,760 nautical mile flight in a fraction just over 24 hours. The RAF has operated the MQ-9 Reaper for over 10 years and the RAF configuration of the MQ-9B will apparently be called PROTECTOR RG Mk1. It just so happens that the RAF is celebrating its 100-year anniversary, so GA-ASI took the opportunity to drop in and say hello at a much smaller airshow at Fairford July 13-15.
Then they announced last week at Farnborough that GA-ASI had been selected to provide UAS to the Royal Netherlands Air Force (RNLAF) following consideration by the Ministry of Defence for the Netherlands. Doesn’t sound exactly like a contract yet, but its close enough to say that the Netherlands will take delivery of the Predator B/MQ-9 Reaper Medium Altitude, Long-endurance UAS. They also reminded us that the Spanish Air Force is to take delivery of MQ-9 systems in 2019.
From a SatNav point of view, we might also be interested that the GPS receiver on this UAV has also been upgraded to add Galileo signal capability — a requirement for what seems to be an expanding number of government forces in Europe. No luck yet in securing better information from GA-ASI about this upgrade, but Farnborough has likely kept them hopping, so hopefully more news later.
Zephyr S High Altitude Pseudo-Satellite UAV

Fresh on the heels of taking on the Canadian Bombardier C-Series program (now the Airbus A-220) and closing the first deal with JetBlue for 60 of these aircraft, Airbus has committed to production of the Zephyr S HAPS (High Altitude Pseudo-Satellite) solar–electric, stratospheric UAV.
Zephyr has an 82-ft. wingspan and is designed to operate on solar power in the stratosphere at an altitude of around 13 miles emulating equivalent services provided by satellite. This is well above clouds, the jet stream and the ozone layer, and importantly well away above regular air traffic. Airbus anticipates the drone flying for up to 100 days without landing (its currently record is 14 days) and to travel up to 1,000 nautical miles per day. It weighs 165 pounds, but can support a payload up to five times its own weight.
The Zephyr aircraft began its maiden flight in Arizona a few days ago — the “qualification flight” is being supported by both the U.K. and U.S. governments — and the U.K. Ministry of Defence is the launch customer for Zephyr. The aircraft has so far logged around 1,000 hours total flight time. The test flight will conclude once engineering objectives have been met. Other solar-cell powered aircraft have struggled with landing or take off due to the large wing, light weight and hence stability under wind gusts, so several projects have not progressed past the R&D stage. Airbus & RAF’s commitment to production indicates their faith in the aircraft design.
Staying with the U.K. theme, the Goodwood Estate in Chichester, England — famous for the Goodwood car racing circuit — has recently hosted the Goodwood Festival of Speed, which apparently included drone racing. And at the same time, a Guinness World Record drone speed record was established.
Wingcopter XBR
The Wingcopter XBR is a tilt-rotor UAV with two lift props and two horizontal velocity props, and the drone flown by teenage drone racer Luke Bannister reached an average of 240.6kmph (~150m/h) over a Goodwood 100 meter track, flying over the measured track in both directions to account for wind. This set the world record for the fastest ground speed by a “remote-controlled tilt-rotor aircraft.” A previous record of 179.6 mph has been achieved by a quadcopter drone rather than a tilt-rotor UAV like the Wingcopter, but there is apparently more drag with type of drone, so its classified as a different category of UAV.
Northrop Grumman Triton High Altitude UAV

Meanwhile, Northrop Grumman released a statement at Farnborough on their continuing discussions with Germany towards the sale of its high-altitude Triton MQ-4C unmanned surveillance drone, but apparently a lot of work still remains. In April the U.S. State Dept. authorized the sale of up to four drones worth up to $2.5 billion, and the German government has since been working closely with the US Navy towards a deal.
People may recall the previous cancellation of the “Eurohawk” program back in 2013 — under which Germany had planned to buy a version of Northrop’s Global Hawk drone — after escalating estimated costs for civil certification of the vehicle hit 600 million euros ($702 million) — not a minor task in any way.Subsequently, Northrop and Airbus Defense and Space have teamed up on a new ‘Pegasus’ program, which will add UAVs to Germany’s surveillance capabilities — drones flying autonomously as high as 60,000 feet to gather a wide array of intelligence data.
The German government plans to buy three of the drones, equipped with sensors and a mission system now to be engineered by Airbus. Preparations for certifying equipment to enable the drones to operate in civil airspace are moving more smoothly this time, but with deliveries to only start in 2025. Northrop developed the Triton, a marine-based variant of the Global Hawk, under a U.S. Navy contract awarded in 2008. And Australia last month said it plans to buy six Triton aircraft for maritime patrol, initially expected to cost A$1.4 billion ($1 billion U.S.).
So, lots of military drone stuff this month — not unusual given the nature of the Farnborough U.K. airshow, even though Boeing and Airbus also use the show to one-up each other’s announcements of commercial aircraft contracts and options. Lots of good news for General Atomics, not so much yet for Northrop Grumman, and some light relief with high speed drone records at Goodwood. Back to more North American UAV news hopefully next month.
