Abstract : Accurate scoring (miss or impact measurement) of missile intercept tests is required to adequately assess lethality. Instrumentation approaches based on a suite of sensors (e.g., Doppler radar Miss Distance Indicator, optical fiber Photonic Hit Indicator, and ground radar tracking) are not capable of meeting the full range of requirements. On the other hand, our long experience with Trident missile system accuracy evaluation and early BMD intercept testing suggests that dual frequency wide-band (P-code) GPS translators on the interceptor and target can meet missile intercept test requirements. This paper describes the GPS system configuration required and presents experimental results to demonstrate two centimeter accuracy in a very high dynamic missile intercept type environment.
