| Abstract: | The phase smoothing pseudo-range method is introduced into SINS/BD tight integration. Carrier phase positioning of BeiDou has higher positioning accuracy, but its extensive and real-time application is limited. The method of phase smoothing pseudo-range can improve the accuracy of SINS/BD integration greatly. In the end, test the effect of the experiment. This method is proved effective to improve the accuracy of SINS/BD tight integration. |
