| Abstract: | An optimal mathematic model of single-frequency precise point positioning was built based on the estimation of ionosphere parameter in the paper.Then after considering all the observation error corrections,the author developed a calculating procedures of single-frequency precise point positioning via Kalman Filtering method.And experiments were done by the real data at last.The results showed that the accuracies about horizontal position and vertical position were both superior to 0.15m,and the dynamic accu... |
