Research on the Positioning Precision of Single CORS System

Accompanying with rapid development of GPS technology,the establishment of continuous operation of GPS satellite positioning system by using net RTK has become a hot spot in the application of GPS technology.The much higher requirement is brought up for the precision and stability of the solution of CORS.The central factors of affecting positioning precision of single CORS system are introduced,and the positioning precision is analyzed.The experimental results indicated that it can entirely and effectively test the positioning precision together with several methods in CORS system.
