摘要: GPS(Global Positioning System)、GLONASS(Global Navigation Satellite System)作为两种实时卫星定位导航系统,得到广泛应用.为满足离线试验研究的要求,设计开发了GPS/GLONASS卫星定位仿真器.该仿真器分析GPS和GLONASS星座的运动轨迹,并模拟卫星接收器的解算,以纯软件的方式实现卫星定位.仿真计算表明此仿真器定位精度与实际接收机相当,可以模拟真实的卫星定位,为仿真调试等研究工作带来便利.

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 fit the needs of offline experiment, a GPS/GLONASS positioning emulator that based on the theory of satellite navigation was designed. This emulator analysed 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 satellite positioning, and makes the simulation works convenience.
