| 摘 要： | 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.

| Abstract: | A visibility prediction method of GLONASS satellites is presented based on the developing experience of GLONASS receiver. Given a certain known status, the spatial rectangular coordinates of the predicted satellite are calculated according to the satellite's operating law. Then the coordinates are converted to topocentric coordinates referenced to the ground observing point. The elevation angle of the satellite is computed and the visibility is obtained. The whole deducing process is discussed in detail . The orbits prediction incorporates impacts of several imperfect forces.True GLONASS almanac are used to calculate the visibility and to verify the results. This method is easily to be applied and deserves high accuracy. It is valuable in GLONASS receiver research. |
