My mailbox is currently overflowing with comments and questions concerning rampant rumors that in the March 2011 time frame a U.S. military reconnaissance aircraft was forced to land during an annual major east Asian military exercise, known as Key Resolve, due to GPS jamming. 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.
In a world where there is more and intentional and unintentional interference with GNSS, it’s a little comforting to hear that technology has been developed which can help us fight back. The proliferation of affordable “Personal Protection Devices (PPDs)” used to mask GPS location — for users who carry location capability but who really don’t want to be tracked — is already been felt at critical points in our GNSS infrastructure in North America. Well, if you can buy a catalog jammer over the Internet in the U.S., how readily available are these things for terrorists and people waging war against us overseas and at home?
