| 摘 要： | 实时卫星位置解算在整个GPS接收机导航解算过程中占有极其重要的地位.正常情况下,多普勒频移应随着卫星高度角的增大而减小.然而,在对实时卫星位置解算实验进行结果分析时,却出现了高度角(仰角)较小的卫星所解算出的多普勒频移不成反比的现象.针对这一现象,文中设计实验进行分析得出:在高度角小于11°时,高度角大小与多普勒频移不成反比.

| Abstract: | The real-time satellite calculation of its position plays a very important role in the whole process of navigation solution of the GPS receiver.Generally,the Doppler Frequency decreases while the elevation increases.However,results in the experiment of the real-time satellite calculation of position turns out that the Doppler Frequency is not in inverse with the small elevation.Against this phenomena,this paper makes a conclusion based on experiment that when elevation is less than 11° Doppler Shift is not in inverse with the elevation. |
