Abstract
This paper use PANDA software to compute the undifferenced ambiguity and receiver clock bias of reference stations. And then the undifferenced corrections of reference stations can be obtained. After modeling for each satellite and passing the corrections to the rover station, the solution of single difference between satellites is computed. Now the errors about satellite and receiver have been cancelled, the user station’s instantaneous ambiguity could be obtained very fast. The proposed method is validated with the data of Hong Kong SatRef network and the west coast of American’s IGS network by coding with C++. The results show that the time of convergence is greatly reduced and the accuracy of positioning can reach to cm-level or sub dm-level.
