Actions Necessary to Reduce Vulnerability and Ensure Availability By Brad Parkinson (From the 25th Anniversary GNSS History Special Supplement) Introduction About 40 years ago, we had a vision for positioning, navigation, and timing (PNT).

North Korea Jamming Incident; LightSquared Issue

September 14, 2011By

The jamming reportedly took place along the northern portion of the 684-mile long Korean peninsula, with the jamming supposedly originating with the North Koreans. The jamming scenario should come as no surprise, but it is the emergency or forced landing due to loss of a GPS signal among other supposed “facts” with which I take issue. read more
