What does the public think of GPS jammer interference?
Several jamming devices/techniques are available on the Internet and will continue to proliferate as a single device may disrupt military and civilian operations worldwide will be attractive to malicious governments and groups.
If terrorists use a jammer on an aircraft, it will increase the range and "hence the effectiveness of the jammer".
The possibility of a GPS-guided weapon clashing in Iraq with a Russian-made GPS jammers, which has anti-jamming technology.
Protect civilian GPS signals and users, including "transfer of appropriate anti-jamming technology from military to civilian use."
A loss of GPS signal on a commercial aircraft would not "cause a catastrophic event" because airliners use multiple navigation systems. Losing a GPS signal can be "pretty challenging" for a general aviation aircraft flying solely on GPS.
General aviation pilots do not use GPS as their only source of navigation, and the potential for interference is a "nuisance" rather than a safety hazard.
While "any average radio engineer" has the knowledge to build GPS jammers, there are few reports of GPS systems being attacked.
The Federal Aviation Administration is developing a nationwide GPS-based precision landing system.
