Precision Pulse Positioning System

Propagation Research Associates, Inc., (PRA) proposes a Precision Pulse Positioning System (3PS) technology that provides a multi-function capability for force protection including the guidance of multiple low-cost blue interceptors engaging multiple targets, the resolution of the blue air picture, and the precision approach mission for blue aircraft. PRA proposes to develop an optimal guidance methodology for guiding multiple interceptors to multiple targets that maximizes total probability of hit. The 3PS concept addresses the need for low cost precision guidance and control of interceptors by creating what is essentially a localized GPS with the purpose of locating interceptors and targets in a radar energy field. Through the use of unique waveforms transmitted from distributed antennas, interceptors can compute a guidance solution to the target with minimal impact on radar resources. Some of additional advantages to 3PS are, 1) 3PS does not require the fire control radar to communicate with or track the interceptor, 2) 3PS allows for the guidance solution to be computed onboard the interceptor allowing for high guidance update rates that do not affect radar duty, and 3) 3PS can be implemented on blue rotary and fixed wing aircraft for precision approach and/or blue air picture definition.
