摘要
分析了基于北斗卫星导航系统中三种导航型卫星的位置求解的异同,阐述了多普勒测速法和位置差分测速法的基本原理。为了分析这两种方法各自的优劣性,做了三组实验,并对其速度结果进行了对比和分析。
The similarities and differences of positioning methods of three different kinds of navigation satellites were analyzed. The basic principle of l）oppler velocity determination and differential position velocity determination were described. In order to analyze the advantages and disadvantages of these two approaches, three experiments were conducted, and the results were compared and analyzed.
