| Abstract: | A high precise GPS observation simulation method using IGS data products was proposed, which overcomes the limitations of conventional method. According to the mathematical models of GPS positioning and orbit determination, some programs were compiled for data testing. The precise from the simulation testing is about 2m, therefore the simulation observations have high applied cost, |
