Abstract
GPS (global positioning system) and GLONASS (global navigation satellite system) which are two kinds of real time satellite positioning systems are applied widely. In order to meet the needs of off-line experiment, a GPS/GLONASS positioning emulator based on the theory of satellite navigation was designed. This emulator analyzed the movements of satellite constellation, simulated the calculation of satellite receivers, and realized satellite positioning in pure software mode. The simulative calculation results show that its accuracy is identical to that of real receiver on the whole. So the emulator can simulate real position of satellite, and make the simulation work convenience.
