I boat? The backup is a competent captain. He'd see the compass heading move and quickly disengage the autopilot. I had a boat for years I'd notice a 5 degree change. Mine was a sailboat so I'd be more sensitive to heading changes than a power boater but still the human is the backup.
Most autopilots don't directly follow GPS, they use GPS to determine a heading, follow it then use GPS to detect drift and re-compute the heading. the heading would be held by a compass sensor in a low-cost setup or in a larger setup a lazer ring gyro backed up by a compass. So a spoofed GPS would cause the autopilot to "think" there was a bigger crooswnd or current and make a bigger heading change. I bet you could hijack a drone not a manned vehicle the pilot is trained to monitor the automation and he'd very quickly turn it off thinking it was broken. On Fri, Jul 26, 2013 at 8:41 AM, J.
