| Abstract: |
| The standard that star _calendar data and position data of GPS 25XL obey is introduced, and the Difference GPS(DGPS) algorithm on smoothing the error from the influence of ionosphere and troposphere is explicated. Based on analysis of the format of RTCM SC-104 telegram,the method of constructing the difference data of RTCM SC-104 format is given.This work offers beneficial reference for the development of corresponding products. |
