| 摘 要： | 由中国矿业大学文昌校区主楼顶站点实测数据,对GPS接收机的多路径效应进行了分析。由于GPS卫星的运行周期为12个恒星时,则连续两天到达同一位置会提前。根据多路径效应和接收机周围环境,以及卫星特定时间位置有关这一规律,通过对连续两天多路径改正值的相关性进行分析,理论与实验验证表明连续两天GPS卫星到达同一位置提前时间为236 s。

| Abstract: | This paper analyzes multi-path effect of GPS receiver based on data obtained from the base station located at the top of main building of Wenchang campus of China Mining University.GPS satellite reaches the same position earlier than the previous day for the reason that the period of the GPS satellite is 12 sidereal hours.This paper analyzes the correlation of correction value of multi-path effect of two consecutive days based on multi-path effect,the environment around receiver and the satellite position at specific time.Theory and practice proves that GPS satellite reaches the same position 236 seconds earlier than the previous day. |
