| 摘 要： | 现代工程GPS基线向量网与地面网联合平差一般是采用二维约束平差的方式在平面直角坐标系中进行。本文详述了基于E1椭球在地方独立坐标系中进行二维约束网平差的原理。算例表明：对于小范围的GPS工程控制网，采用二维约束平差在精度和实用性方面都能满足需求。

| Abstract: | Modern engineering of GPS baseline vector network and the ground network combined adjustment is generally conducted based on the 2D constrained adjustment manner in the plane rectangular coordinate system. 2D constrained net adjustment is described based on E1 ellipsoid in local independent coordinate system detailed. The example shows that in the small range of GPS control network, the 2D constrained network adjustment can meet the demand in terms of the accuracy and practicality. |
