Future Requirements for GPS Tactical Ballistic Missile Guidance

Jeff L. Rhea, Brian T. Baeder

Abstract:	The Army has employed GPS user equipment for troops, vehicles (e.g., troop transports, launchers) and aircraft. Further employment has been made possible by the reduction in receiver package size. GPS is an ideal candidate for aiding missile guidance units to enhance the overall system effectiveness. However, the demands on GPS for a ballistic missile application are significantly different than most user applications because of the associated timelines for prelaunch and flight. In addition, concerns of receiver initialization and dynamic requirements for missile systems complicate the application of GPS. This paper details the requirements and future needs the Army is likely to place on GPS integration into a missile system including both receiver and antenna for successful operation in a ballistic missile environment. Concerns hindering the application of GPS systems include electronic countermeasures (ECM), performance under missile dynamics, and overall system cost. A discussion of these concerns and their associated mission impact are presented. In conclusion, a proposed scheme applicable to a tactical missile system is discussed, indicating typical parameters used and the advantages gained over a non- GPS aided mission.
