| Abstract: | The influence of multipath errors on the observation results of GPS survey is discussed. The principle of multipath errors is studied,and the effective magnitude of the pseudo range position and carrier phase and the multipath errors caused by the reflection coefficient and satellite self are explored. At last,the methods for reducing and eliminating the multipath errors are described. |
