Optimal Antenna Configuration for GPS Based Attitude Determination

Christopher J. Comp

Abstract:	An optimal geometry antenna configuration was de- signed such that GPS attitude determination perfor- mance was enhanced. The final design was an inverted orthogonal triad with master to slave baselines of 1.22 meters, and the master antenna positioned 0.707 me- ters above the slave plane. An antenna structure was constructed to conform to these design parame- ters. The orthogonal antenna configuration was tested against several non-orthogonal configurations. For this test, both structures went through a set of predefined rotations in yaw OI heading, and the resulting differ- ential phases and attitude solutions were analyzed and compared. The orthogonal structure showed marginal improvement for differential phase, and significant im- provement in the attitude solution. It was concluded that the improvement in the attitude performance was achieved by virtue of the optimal antenna geometry.
