GPS (Global Positioning System) Error Budgets, Accuracy and Applications Considerations for Test and Training Ranges

摘要

A Triservices study, currently in progress, will develop representative test and training range instrumentation configurations based on NAVSTAR Global Positioning System (GPS) technology, evaluate performance capabilities, and develop cost information. During the early phase of the study a collection of GPS documentation was established for reference purposes. This documentation along with experience from other GPS projects at WSMC provided the basis for the report. This report provides information that should be useful to range analysts developing and evaluating GPS-based instrumentation concepts at the test and training ranges. Some of the subjects are not thoroughly developed and may require further work. Subjects addressed include definition of performance evaluation terms, Doppler data processing, use of pseudo-satellite ground stations, two and three dimensional solutions, receiver and translator configurations, and vehicle dynamics effects on receiver operation.
