| 摘 要： | 在GPS控制网数据处理中,对长度投影变形的处理至关重要。本文通过选取抵偿投影面很好的限制了矿区内的综合投影变形,为艾娜克铜矿工程测量控制网的建设提供了坚实的理论依据。同时,边长尺度强制约束法的运用进一步消弱了长度变形,使得新建控制网和原控制网能够很好的吻合,为利用前人的地质勘探及测量资料创造了条件。

| Abstract: | It is very important to deal with the deformation of length projection during data processing of GPS control network. In this paper, the deformation of length projection is effectively restricted by choosing a compensation projection plane; which provides a solid theoretical basis for the establishment of Aynark copper project control network. Meanwhile, the application of length--scale forced restraint method not only further weakens the length deformation, but also makes the newly--built control network welt accord with the original one; which creates conditions for using geology exploration and surveying materials left by former Soviet Union. |
