自由定向坐标系中GPS网的平差计算

GPS Net Adjustment in Free Orientation Coordinate System

引进了与自由定向坐标系相对应的局部椭球，导出了ＷＧＳ－８４坐标系中的ＧＰＳ（全球定位系统）基线向量变换到局部椭球坐标系中的计算公式，讨论了局部椭球坐标系中ＧＰＳ网的平差计算和附合闭合差计算的方法与步骤．根据此模型编制的软件已经在生产中得到应用．

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.
