| Abstract: | In GPS network, the reference points quantity,combination metnoa ana distributing tion affect the accuracy of GPS positioning result. The unreasonable combination and distribution way will affect the GPS net inherent high accuracy. In order to acquire result of height quality, it is necessity scientific to select the reference points quantity and distribution when build high-grade control net, so that we can find out the optimal combination plan. The reference points combination and distribution method are introduced in this paper, and drawn the related conclusion by the example in the GPS network. |
