Doppler Velocity Sensor APN-200 Error Model and Flight Test Results

Abstract

The individual sources of error in a Teledyne-Ryan APN-200 Doppler velocity measurement are discussed. Also included is the velocity error due to INS attitude reference error. A complete Doppler error model is constructed, including estimates of the one-sigma values of error parameters. Error model simplification for Kalman filter synthesis is discussed. Data, from a 7 August 1973 flight test of an APN-200 at Holloman Air Force Base, are analyzed. The Doppler velocity performance, including random noise level and slowly varying error, is found to be in agreement with the accuracy predicted by the error model.
