| Abstract: | This paper summariges the methods for translated GPS extra-traxzctory measuring data and state estimation, discusses in detail various differential methods for processing observation data and compares their advantages and disadvantages. Mathematical simulation showed that it is very high for the accuracy of state estimation to use the GPS in trajectory measurement. |
