Abstract : This report covers Phase II work on the compass research program. The Phase II work represents a change from the Phase I approach which used high power and typical flux gate data processing whereas Phase II used low power with Lockheed proprietary data processing methods. Application of this low power data processing approach reduced or eliminated previous Phase I problems with data pumping, harmonic distortion, and compass return to zero. In addition to investigation of sensor and data processing techniques, this report describes methods of meeting compass operational requirements at high latitudes and several approaches for stabilization of compass data against environmental forcing functions.
