GPS控制网的优化设计

Optimal Design of GPS Control NetworkAbstractWith the rapid development of GPS observation technology and its wide applicationin terms of mapping,optimization design of GPS control network has been more attention.In the fabric of peace difference model net programs are different from the classicalaspects,it has a big difference between GPS control network with the classic controlnetwork.The paper analyzes the design principle for GPS controlling network,has thedetailed introduction for the principles,the steps and methods of the optimization design ofGPS controlling network according to the factual requirement for the design of thecontrolling network,and points out the net-laying should be reasonable by combining withfactual situation and the reliability,the accuracy and the efficiency cost should beconsidered in the factual operation process,so as to find the best programme.Key Words:GPS control network arrangement principle optimal designaccuracyestimation
