根据GLONASS卫星频间差与接收机型号之间的关系,对GLONASS卫星频间差进行预报。讨论了引入GLONASS卫星频间差的导航定位模型。利用GLONASS卫星频间差的预报值选取IGS观测站数据进行导航定位的实例解算,计算结果表明引入GLONASS卫星频间差预报值可以明显提高导航定位的精度。
We analyze the correlation between GLONASS IFDB and receiver types and predict GLONASS IFDB based on derived model. By introducing GLONASS IFDB, several tests are performed using observations from several IGS stations. Results show that the navigation accuracy isremarkably improved by adding GLONASS IFDB.
