摘要
提出基于GLONASS卫星导航和北斗无源卫星导航系统的卫星组合导航模式,针对组合导航模式中存在的地球模型、坐标系、系统时间等不一致进行分析,并建立北斗无源导航系统与GLONASS系统之间的系统时差数学模型,再根据坐标转换与统一,运用最小二乘的方法进行用户位置定位解算,并通过实际飞行数据进行验证,证明这种组合方法是可行的。
A combination navigation mode based on GLONASS and Beidou passive navigation is proposed in this paper. The differences of earth modes, coordinates, and time systems between those two navigation systems are analyzed. The mathematic mode of time difference between the Beidou system and GLONASS system is built up. In terms of coordinates transform and integrity, user position is resolved by least square method. The method is validated by real experimental flying observation.
