Abstract : This final technical report describes the research performed by the Colorado Center for Astrodynamics Research for the Naval Research Laboratory (NRL) on GPS Based Attitude Determination for spacecraft over the period 01 September 1993 - 31 August 1995. The overall project encompasses various methods for using GPS to determine the attitude of a spacecraft in near Earth orbit. The specific topics covered are - (1) attitude estimation for a gravity gradient stabilized satellite using point solution and Kalman Filtering techniques; (2) identification and mitigation of multipath in GPS carrier phase data; and (3) frequency and time domain techniques for attitude estimation of a spinning satellite. This report represents a compilation of four semiannual technical reports provided to NRL over the course of the project.
