| Abstract: | Multipath error seriously affects the precision in high precision GPS applications,and it is difficult to eliminate.The paper introduced the mechanism and characteristic of the multipath effect,mitigated the multipath error using differential correction between successive two satellite operational cycle in same environment and moving average method in coordinate sequence of successive epoch.These two methods are both to advance precision of the positioning. |

| Keywords: | multipath characteristic moving average precision |
