Abstract:	The Global Positioning System (GPS) provides a means of accurately determining position, velocity and time and has gained widespread acceptance in both military and civil communities. The GPS satellite signals are transmitted at a very low power level and are therefore susceptible to intentional and unintentional interference. Without anti-jam technology, low power, narrowband or wideband interference sources can render GPS systems inoperable. Lockheed Martin has developed the multi-beam GPS Spatial Temporal Anti-Jam Receiver (G-STAR™) to address this weakness. G-STAR™ has been in production for several years and has been adapted to address a wide range of applications. Tests performed at government laboratories have demonstrated G-STAR™'s outstanding AJ performance. The multi-beam digital output capability provides the high integrity performance needed for precision approach and landing applications. This paper provides a description of the operation of GSTAR™ and a summary of how G-STAR™ has addressed this problem in the past and will continue to meet the GPS AJ challenges in the future.
