GPS工程控制网的优化设计

由于GPS测量精度高、效率高、灵活性强,其应用越来越广泛。文章结合实际工程,通过两次布设网点,并经过严密的计算。得出只要在建立GPS工程控制网时充分考虑布设条件及网形的几何结构,并严格按照规定观测,认真处理观测数据,最后所得的精度就一定有所提高。

Because of its high precision, high efficiency and flexibility, GPS has been used more and more widely. The paper isbased on actual projects, written by setting up the net point twice which is set through accurate calculation. It is concluded that aslong as the GPS engineering control network is established, the layout conditions and the geometric structure of the network are fullyconsidered, the observation data are strictly observed, and the observation data are seriously handled, the accuracy of the final resultis supposed to be improved.
