| Abstract: | Based on the Zero Baseline Method,the interior noise level and phase center variation of the six Leica GRX1200 instruments are tested.The data processing and the results’ evaluation are made by using TEQC and GAMIT/GLOBK software.Combined with the testing procedure of Leica,this paper expounded how to test the GPS instrument according to the standards without standard testing ground by the measurement department. |
