Testing High Precision Space Receivers versus LightSquared Interference

S. Esterhuizen, D. Turbiner, D. Stowers, L. Young

Abstract:	This paper describes various tests held to document the impact of LightSquared signals on JPL’s high performance GPS receivers, and will emphasize test design. The first test was done at the Jet Propulsion Laboratory, where interference was introduced into the receiver under test using a directional coupler, that is, it was a conducted test as opposed to a radiated test [GARMIN2011]. We will describe the methods of generating the simulated GNSS and LightSquared signals, as well as the careful calibration of the system noise realized in the test setup. A brief account will be given of two radiated tests consisting of anechoic chamber and live-sky testing held at White Sands Missile Range and at Holloman Air Force Base. We will describe the strengths and weaknesses of each test type, and a summary of results will be presented.
