Investigation of Critical Issues for Army Users of the NAVSTAR Global Positioning System

Abstract

This report addresses critical issues relative to the projected performance of Army users of the NAVSTAR Global Positioning System (GPS) in a battelfield environment. This study represents a continuation of an earlier Army user performance analysis conducted by TASC and reported in AFAL-TR-74-294. An assessment is provided of the practicality and navigation performance obtainable with the deployment of directional receiver antennas by the Army manpack user. A realistic assessment of the vulnerability of this user to electronic jamming from both ground-based and airbrone jammers is also provided. Several techniques available to the user for countering a jamming threat are discussed and evaluated. Lastly, an assessment is presented of the unique error effects of receiver crystal oscillators (clocks) on user navigation performance. Error effects considered in this study include those due to vibration, shock, warm-up, temperature variations and acceleration on the clock pattern.
