| Abstract: | GPS multi-path effect is an important error source of GPS survey.It seriously influences the GPS measurement accuracy.Based on the research on multi-path characteristic,the error characteristics of the multi-path effect were analyzed by using the principle of generating multi-path from starting and the function of the multi-path signal.Finally,multi-path effect under different circumstances was given by using simulation,and the multi-path effect with the space-time and value range characteristics was ob-tained. |

| Keywords: | multi-path simulation space-time characteristic value range characteristic |
