The Application of the NAVSTAR Global Positioning System to the Evaluation of the Next Generation Long Range Ballistic Missiles

Abstract

The NAVSTAR Global Positioning System (GPS) is a joint services program currently undergoing concept validation. The program is managed by the Air Force with participation by the Navy, Army, Marines, and Defense Mapping Agency. When fully deployed, GPS will provide highly precise position and velocity to a variety of users. The Magnavox Advanced Products Division, under several funded contract activities, is participating in the development of several user equipments and studying the application to many others. This paper discusses the results of a study performed for the Space and Missile Test and Evaluation Center (SAMTEC) Vandenberg AFB to determine the feasibility and capability of the use of the NAVSTAR Global Positioning System as a tracking instrument and guidance evaluation system for the next generation ballistic missiles. The paper examines three primary approaches to the missile tracking problem using GPS. Recommendations for missile instrumentation are provided based upon studies in areas such as mission scenario, environmental factors, systems requirements and constraints, and configuration analysis.
