| 摘 要： | 利用全球定位系统(GPS)所建立的空间基线向量网,对于改善已有地面网,分析网的系统误差和进行地球动力学的监测等具有广泛的意义。本文着重讨论了上述空间基线向量网和地面控制网的三维联合平差和二维联合平差的方法和模型。指出,为了避免地面网高程误差以及引入地面网尺度因子的模型误差对三维联合平差结果的影响,在二维大地坐标系统中进行上述两网联合平差的方法具有重要的现实意义。

| Abstract: | It is of extensive significance to establish a GPS space baseline vector network for the improvement of an exisiting terrestril network, the analysis of systematic errors of the network and the monitoring of geodynamics. In this paper, the methods and models for threedimensional combined adjustment of the space baseline vector network and the terrestrial control network are discussed in great detail along with those for the twodimensional combined adjustment.It has been pointed out that the combined adjustment method for the two networks in twodimensional geodetic coordinate system is of practical importance in order to avoid the effects on the results of threedimensional combined adjustment resulting from the errors of heights of the terrestrial network and the model errors due to the introduction of scale factor to the network. |
