It uses GPS so it's dead on arrival against near peer adversaries
- dgrin91 2y agoIt has "hardened" GPS, whatever that means, and it presumably is not singularly reliant on just GPS
- greenavocado 2y agoHardened GPS is real but military missile systems with it have had a very hard time in Ukraine against Russian targets. Reasons unknown.
- verdverm 2y agoYou can pump a lot more energy into electronic warfare systems on the ground than in the air. The offensive missiles are also not the latest and greatest
- mikeiz404 2y agoIf the GPS signals are coming from above and the jamming is coming from below wouldn't this be strongly resistant to such attacks assuming the receiver is shielded from signals from below? Edit: Perhaps it's not a good assumption that a near peer would only jam or spoof from below. If they have satellites above then they could interfere from above as well.
- mikeiz404 2y agoAlso found this: > Signals received from GNSS Satellites are usually very weak and are thus susceptible to deliberate or unintentional interference. It is very easy for an adversary to intentionally introduce RF interference into the GPS frequency bands, referred to as jamming, and deny the user position, navigation, and timing (PNT) data. Using CPRA antennas can help protect against this changing the antenna reception patterns to null out the jamming signals and direct the beams towards the satellites. https://www.everythingrf.com/community/what-are-controlled-reception-pattern-antennas https://www.everythingrf.com/community/what-are-controlled-r...
