BAE provides enhanced GPS technology for F-15 fighters – UK Defence Journal


Sep 18, 2022

The company’s Digital GPS Anti-jam Receiver (DIGAR), they say, will ensure the reliability of military GPS systems for aircraft operating in challenging signal environments.
“DIGAR uses advanced antenna electronics, high-performance signal-processing, and digital beamforming – a capability that combines 16 steered beams – for better GPS signal reception and superior jamming immunity. These capabilities are critical for high-speed aircraft as they manoeuvre through the battlespace.”
The F-15 Eagle is the second U.S. Air Force fighter platform to receive DIGAR GPS upgrades, following the F-16 Fighting Falcon. DIGAR also provides GPS capabilities for intelligence, surveillance, and reconnaissance aircraft as well as multiple unmanned aerial vehicles.
“Modern airborne missions require accurate positioning and navigation data, and GPS systems must be able to withstand adversaries’ best disruption efforts,” said Greg Wild, Navigation and Sensor Systems product line director at BAE Systems.
“Our DIGAR antenna electronics are trusted to protect these platforms in contested environments.”
According to a news release from the firm:
“BAE Systems’ family of military GPS products offer size, weight, and power characteristics suitable for a variety of applications, including handheld electronics, vehicles, unmanned aerial vehicles, aircraft, and precision-guided munitions. In addition to GPS Anti-Jam products, the company is currently delivering advanced GPS products compatible with the next-generation M-Code satellite signal, and is developing the next generation of receivers to ensure dependable GPS for warfighters across land, air, and sea domains. BAE Systems work on military GPS technology takes place in Cedar Rapids, where the company is investing more than $100 million to build a 278,000-square-foot, state-of-the-art research and manufacturing center.”
Quite interesting how long a lot of these Cold War airframes have served for. When you think the first f15A came off the production line 50 years ago and it’s design was from the modern to late 1960s. Even they very youngest f15c airframe is 35 years old. Infact the F15 makes the tornado look like a bit of a spring chicken. Such a shame we retired such an effective aircraft as the tornado, when other nations invest to keep their aircraft flying.
I don’t think we could have afforded Tempest if we still ran Tornado and Harrier. Even keeping two main platforms going and developing another is a costly act in these 2% GDP days. I’d have like us to keep working on the Hawk too.
Yep, unfortunately when you make such choices you do have to examine if you are spending the correct amount of money on risk mitigation ( the military are essentially a very large set of risk mitigations). In reality they probably should have kept the tornado squadrons running until they could replaced like for like by F35B squadrons. I suspect that if that decision came up now they may not have scrapped tornado until we had two full squadrons of F35B and there was some increased weapons integration. Sometimes the risk and need has to dictate the spending level and not… Read more »
Totally agree with that last paragraph. I think at the end, our Tornado GR4’s were about knackered after nearly 3 decades of continuous operational use. The shame is we don’t have a larger Typhoon force to take up the slack. Typhoon force is meeting all operational requirements, and is doing a sterling job. But keeping the fleet at around 160 would have given the RAF more depth, while the F35 fleet is gaining in numbers and experience.
Same with the US navy, they have an ability to just keep going. A lot of it could of been to do with the fact they were able to be built in such large numbers due to the Soviet threat, then the inevitable collapse of theat empire then the gulf war came along and it’s there where they really proved what a reliable airframe it is. Then came the changes post gulf in budget setbacks and literally nothing really on the drawing board for a replacement, especially in like for like numbers that wouldn’t of been possible that they were… Read more »
You can transform a fighter like F-15 into a multimission aircraft if the airframe has size for that, while transforming an attack aircraft like Tornado into a multimission aircraft is complicated specially since it was made for low level.
It was also a smaller aircraft with a very high density.
It would also probably better that all Tornados had the ADV size with extra fuel.
Losing Tornado,Harrier and jaguar was all down to two men called David Cameron and George Osborne oh and Nimrod MR4 plus the damage to the Navy and Army .For me away.😕
Jaguar GR3, Sea Harrier FA2 and Tornado F3 was all axed before the Coalition gov came to power in 2010. The RAF Harrier GR7/9 force had also been reduced to a lower number before 2010. Tornado GR4 numbers had also been reduced before 2010. Both Labour and Conservative govs have been equally bad at managing defence, and having short term views when it comes to the spending rounds.
Agreed, Cameron & Osbourne were a disaster for the UK.
Wonder whether the rather ridiculous firewall constraint that BAE (US) cannot discuss/share various program specifics w/ BAE (UK), will be relaxed/eliminated as a result of AUKUS? Collectively, political leaders have to realize we have returned to great power confrontation/conflict. We will soon be confronted w/ multiple existential threats; ChiComs plan to triple nuke inventory by 2030. Deliberately hobbling our collective response appears the height of folly.
Would be interesting to know whether BAE Inc. contribution is factored into UK contribution on the F-35
Excellent point. Presume BAE accounting reports are on web. Anyone w/ an accounting background lurking?
ChiComs plan to triple nuke inventory by 2030
It does not matter if they quadruple or decuple their inventory, any nuclear exchange between members of the club, will result in an uninhabitable planet Earth as we know it. Elementary physics.
Recently read an article, published by an apparently reputable research group, that predicted extended survival for selected territories in Southern Hemisphere, including Oz and NZ, for scenarios short of full scale exchange; eerily reminiscent of the novel “on the Beach.” Claim was that these areas would avoid effects of nuclear winter and populations would not succumb to starvation Surprised me, as well; who knew there might be “winners?” Will attempt to find link again and post, if successful.
… published by an apparently reputable research group …
No such thing, cloud cuckoo land waffle! No-one has seen or been to Armageddon, after an all-out nuclear exchange.
Believe prediction based upon amount of debris that would be circulating in atmosphere combined w/ latest meteorological models. Correct that prediction is only as accurate as inputs and the model validity itself. No sane person would wish to press to test. Unfortunately, doesn’t guarantee event will not occur.
Doubtful, but that’s IF Russia or China neglect to target them. Then there’s the melting of the ice caps a nuclear armageddon would cause, raising sea levels 50+ metres which would wipe out most coastal settlements including most major cities.
On unrelated news, our government has just cleared the sale of Inmarsat to the US. So much for us becoming a world leader in space technology. Megitt just sold for £6.3 bn. Ultra Electronics for £2.6 bn. Ultra is being sold to Cobham, which used to be British until they sold that off too. These companies are often broken up and asset stripped. The majority of Cobham was apparently sold on.
Kwasi Kwarteng and Jacob Rees Mogg: selling England by the pound.
The idiot Krazey Kwarteng again?
The buyers know that the promises the UK Govt require them to make are worth nothing as they will not be enforced, so they can asset strip to their heart’s content.
No vision. No sense. No future.
Cobham was dismantled within about 18 months – decent details in Wiki entry.
Kwarteng was the earlier ones, this latest is J R-M.
Want to put your own money on it? The issue is if it not the foreign buyers the taxpayers will have to fill it.
Cobham got too aggressive in takeover activity and found itself in deep financial trouble with excessive debt. Any turnaround was thwarted when it ran into trouble on the Boeing KC-46a.There was no British equity fund that would take it over and rescue it from British mismanagement. There are 3500 Brits still employed today because of that purchase. What assets were stripped?
