| 摘 要： | 为验证北斗全球系统卫星新型导航信号体制、星间链路和高精度原子钟等关键技术,中国于2015年3月30日至2016年2月1日间发射了5颗新一代北斗试验卫星。试验卫星除了播发新的民用信号B1C和B2外,同时还播发B1I和B3I平稳过渡信号。试验卫星导航信号的伪距质量以及北斗现有工作卫星存在的与高度角相关伪距误差问题在新一代北斗卫星上是否得到解决是大家普遍关注的问题,将基于北斗试验卫星实测数据对此进行初步评估与验证。

| Abstract: | In order to carry out the demonstration of new type of navigation signal, inter-satellite link and high precision atomic clock, five new-generation BDS experimental satellites have been launched between March 30, 2015 and February 1, 2016. BDS experimental satellites also transmit legacy B1I and B3I signals besides the new civil B1C and B2 signals. The pseudorange quality of experimental satellites and whether the satellite-induced pseudorange variation existing in the current BDS satellites still exists are in urgent need of evaluation and validation, which are addressed based on the real data of BDS experimental satellites |
