  • I have all ways said, since the 'lost' drone in Iran, jammed or spoofed you need to deal with loss of gps. A simple dead reckoning reality check with gps should detect spoofing. I find it hard to believe GeneralBoeingNorthrupGrummanAtomics&$theirBrothers haven't figured this out.

    Sensationalism at its best. Why mess with a John Dear combine with auto steer and get the farming community in an up roar?

  • What about solar storms ;-)
  • In order to get rid of such GPS spoofing, with accurate Dead Reckoning, an algorithm in the code can be implemented so that, the autopilot does not use the GPS signal for that period of time during which it observes sudden appreciable change of GPS Lat Long, at time when there was almost no change in acceleration in concerned direction.

    Autopilot will consider the and process the GPS Lat Long data for navigation so long as there is not sudden change of North, I mean GPS lat long, while continuously monitoring the data from Dead Reckoning.

  • In reality, the hacking will be way much more complicated due to encryption and etc.

    Also, I posted this about a week ago:

  • I agree, this should be the right picture:


  • I like the SUAS article better.  The choice of pictures make it sound like they hacked a predator when they actually hacked a small quad.

     Because GPS systems work by measuring the time it takes for a signal to travel from the satellite to the receiver, a successful spoofing requires that the attacker know precisely where the target is so that the spoofed signal can be structured with the proper signal delays. A GPS spoofing attack begins by broadcasting a slightly more powerful signal that produces the correct position, and then slowly deviates away towards the position desired by the spoofer, because moving too quickly will cause the receiver to lose signal lock altogether, at which point the spoofer works only as a jammer.
