EVALUATION OF GPS RECEIVER PERFORMANCE UNDER HIGH DYNAMIC CONDITIONS

Abstract

Global Positioning System (GPS) sensors have the potential to provide precise position, velocity, and timing information in high dynamic applications. Missile flight-testing is one such application where accurate relative positions are important. GPS instrumentation can provide the high accuracy while offering both significant cost savings and improved confidence in the test results when compared to existing methods. To date, the use of GPS in missile flight-testing has been limited due to a lack of demonstrated GPS receiver tracking capability in high dynamics. This paper evaluates several currently available GPS receivers for both their tracking capability and their measurement accuracy in high dynamic environments.
