GPS Spoofing experiment knocks ship off course

Inside GNSS reports on an experiment to to use a GPS jammer
transmitter to send a ship off course without it being aware

Jamming GPS signals is very straight-forward and a simple jammer can
be made for a few dollars, however, such jamming alerts the target as
an alarm will be triggered that the GPS signal has been lost.

Considerable research has been carried out in recent years into
developing ways of tricking a GPS receiver into believing it is in a
different location without triggering alarms.

Dee Ann Divis writes in the publication Inside GNSS about a research
team from the University of Texas which has successfully spoofed a
ship’s GPS-based navigation system sending the 65-metre yacht hundreds
of metres off course — without raising alarms or triggering a hint of
the course change on the onboard monitors. The team have also spoofed
Drones (UAV's).
