基于GLONASS接收机研制的实践,提出了一种GLONASS卫星可见性的预测方法.根据GLONASS卫星的某一已知状态和GLONASS卫星的运行规律,计算GLONASS卫星的地心地固空间直角坐标,然后转换为以地面观测点为参考的站心极坐标,求出卫星的高度角,得出卫星对于地面用户的可见性.这种算法计算简便,准确度高,在接收机的研制中具有实用价值 Based on the practice of GLONASS receiver, a method of predicting the visibility of GLONASS satellites is proposed.According to a known state of GLONASS satellite and the operation of GLONASS satellites, the Cartesian coordinates of geosynchronous earth space of GLONASS satellite are calculated and then converted to Taking the observational point of the ground as the reference, the polar coordinates of the station are obtained, and the altitude of the satellite is obtained to get the visibility of the satellite to the ground user. The algorithm is simple and accurate, and has practical value in the development of the receiver
