Abstract : This report presents a description of the PERSHING PII Inertial Measurement Unit field gyrocompass test which provided the first accuracy data outside a benign laboratory environment. Results are presented and discussed. It was determined that RMS and average errors increased under field conditions but the standard deviation, about the average at each azimuth heading for which data were taken, was essentially the same as laboratory results. A temperature related anomaly was identified which will be an item for close scrutiny during future tests. No catastrophic performance breakdown occurred; however, since errors tend to grow when the equipment is operated outside a benign laboratory environment, no relaxation of the current gyrocompass accuracy specification is recommended.
