HAI Advises on GPS Interference
Advice comes out as latest round of interference testing begins in Barstow, California.

The Helicopter Association International (HAI) has released a document, Understanding GPS Interference Events, to explain the practice of purposefully jamming and/or testing of GPS signals, as well as where members can go to get information on Notams associated with the GPS interference exercises. The Department of Defense is required to conduct the exercises, HAI noted, adding that they involve intentionally degrading or outright denial of the GPS signal.
