The Future of GPS Jamming Testing in the United States

Eileen A. Bjorkman, Nicholas Garcia

Abstract:	The 746th Test Squadron at Holloman AFB, New Mexico, is responsible for test and evaluation of inertial navigation systems (INS), Global Positioning System (GPS) navigation systems and user equipment, and integrated INS/GPS systems. Testing of GPS user equipment and integrated systems requires jamming testing. As GPS use proliferates in both the military and civilian commuuities, open-air jamming clearances for testing are becoming more difficult to obtain due to the impacts on users not participating in the testing. This paper will describe the current GPS jamming test methodology and various techniques proposed to minimize GPS jamming impacts to non-participating users. These techniques include increased use of modeling and simulation, indoor hardware-in-the-loop test facilities, and methods to minimize the impacts of open-air testing such as narrow- beam tracking jammers and injected jamming systems.
