The article about the RQ-170 states that the aircraft uses inertial guidance for its flight path so as to avoid GPS spoofing attacks. But then no explanation is given for how that might have failed. Is anything else known about how the attack worked?
- sudosysgen 4y agoI looked far and wide, and there's nothing. However, inertial guidance is subject to drift, so if you spoof the GPS slow enough you can bypass inertial guidance as a protection. The most interesting part of the RQ-170 story however is how they managed to track it accurately enough for GPS spoofing to begin with - you need a track accurate to a few dozen meters to do that, and it's supposed to be super stealthy even beyond the stealthiest fighter jets making that impossible.
