Abstract
Because of the characteristics of BDS satellite constellation and the accuracy of satellite orbit and clock error, the initialization time of the traditional ionosphere-free combination precision point positioning (LC-PPP) is longer. To solve this problem, we use the Zero-difference Zero-combination PPP (ZDZC-PPP) algorithm to quickly initialize BDS PPP. The algorithm can take advantage of a priori information of ionosphere as a prior restraint enhancing the equation strength. Therefore it makes it possible to shorten the PPP initialization time. This paper introduces the ZDZC-PPP algorithm and analyzes the difference between it and the LC-PPP. Compared with the traditional LC-PPP, the calculation results show that the ZDZC-PPP can effectively shorten the initialization time and can obtain the high accuracy of the positioning results by MGEX observation data.
