| Abstract: | The importance of subway GPS control measure- ment and the optimal design of GPS net are shown briefly. The method of solving GPS using LGO combined with CosaGPS is introduced. The problem of assigning the range＇ s accepted tol- erance in GPS net repetition measurement is discussed. Accord- ing to the practical experience, the Corresponding solutions to a range of common problems is summarized. |
