GPS attitude determination using a genetic algorithm

Abstract

In this paper, a new technique that uses a specially tailored genetic algorithm is proposed for attitude determination via GPS carrier phase observables. The technique overcomes restrictions due to computational overheads incurred by existing techniques such as the ambiguity function method. We present experimental results which show that the algorithm is able to efficiently search the complex search space imposed by the problem in addition to being immune to cycle slips compared to other conventional methods.
