Rapid Ambiguity Resolution for Single Frequency Receiver

Abstract:

The algorithm of rapid ambiguity resolution for single frequency receivers is presented in this paper. Firstly, a sequential least square method is applied to decrease dimensions of the observation matrix of satellites. And then, the regularization method is applied to improve the accuracy of the float solution of ambiguities. Finally, the evolutionary method is applied to search the fixing solution of ambiguities. The experiment results show that the proposed method is fast and efficient for users to perform kinematical positioning and the difference between the positioning results of the proposed method and the results of GrafNav is in 2.5 cm.
