The Application of Adaptive Genetic Algorithm in GPS Attitude Determination

In this paper, the adaptive genetic algorithm combined with the whitening filter is proposed to search for correct ambiguities for GPS attitude determination system. First of all, the float ambiguities are carried out by Kalman filter, and then the whitening transformation is used to reduce higher correlation of integer ambiguities. Finally, the decorrelated ambiguities are searched in the transformed search space using adaptive genetic algorithm. The experimental results demonstrate that the proposed approach is feasible and efficient for GPS attitude determination system.
