| Abstract: | A large amount of required observation data can be obtained by using GPS simulation technology without field work.The technology can also be used for the optimal GPS site selecting,the best field work planning,the analysis of GPS measurement precision,the reliability research under sophisticated environment and various GPS application researches.The theory,method and error models of GPS simulation were introduced in this paper,and then Visual Basic.Net program language was used for the secondary development based on ArcGIS.A simulation software for static GPS observation based on DEM was developed,by it the optimal observation location and time could be obtained. |
