| Abstract: | After the establishment of Beidou foundation reinforcement system,the 2000 national geodetic coordinate system has been provided.How to convert the three-dimensional position to the operation mode of plane+elevation in practical local application is a difficult problem in the application of Beidou foundation reinforcement system.This paper develops an online coordinate conversion system based on Beidou foundation reinforcement system.The system can realize the conversion of three-dimensional position to plane+elevation operation mode through the special network mode,which solves the difficulties in actual operation and realizes the full dynamic and high-precision three-dimensional measurement capability of Beidou foundation reinforcement system. |
