Jamming it and misdirecting it are much different animals.
Very few recievers would, or even could, use one signal to triangulate and locate.
At sea is a slow moving target.
Thank you X-D...
#1 test, a YAGI ant, which is a focused main lobe, that while effective near shore and with tracking, would have to be very powerful to reach an aircraft. (and would still have to track) likely not able to affect widespread issues.
#2 test results, the jammers were 5m and 15m from the GPS antennes?
Surface vessels have INS, so while a temporay disrution would affect the GPS location, the INS would not be affected until the disruption lasted 15 mins or more, and then IRS drift degredation of location would occur.
