摘要
针对北斗卫星导航系统(BDS)仿真问题,提出了一种基于IGS广播星历及STK软件的BDS仿真方法,首先根据广播星历解算北斗导航卫星在星历参考时刻的位置速度信息,然后利用星历参考时刻的位置速度信息,在STK/Astrogator模块中进行轨道建模,最后对所仿真的BDS星座的真实性以及星座性能进行了分析。仿真结果表明:利用文中方法仿真的BDS星座真实性较高;从星座的性能分析可知,目前BDS已在全球具备良好的覆盖品质,基本能够为全球用户提供高精度的导航定位服务。所做工作对BDS的全面组网建设和后续业务化应用具有一定的参考意义。
A simulation method of BDS with IGS broadcast ephemeris and STK software is proposed for simulation of Beidou navigation satellite system. Initial velocities and positions of Beidou navigation satellites are calculated from IGS radio ephemeris. By using the STK/Astrogator module,BDS based on the initial velocities and positions above,then validity and performance of the simulated BDS are evaluated. The results shows that the simulated BDS is real and the BDS which have achieved global super coverage merit can mainly provide service of navigation and position with high precision for users around the world. In addition,the paper shares some significative references to the comprehensive networking construction and followup business application of BDS.
