| Abstract: | in this paper the local ellipsoid which corresponds to free orientation coordinate system is first introduced. Then the formulas which transform the GPS baselines from WGS-84 coordinate system to the local ellipsoidal coordinate system are derived. Finally the model and computational procedure of GPS net adjustment and position misclosure calculation in the local ellipsoidal coordinate system are discussed. The software written according to this model has been used in practice. |
