| 摘 要： | 不同等级或者不同时期布设控制点都可能存在较大误差,如果以误差较大点做起算,都会扭曲GPS测量的精度,严重影响GPS成果可靠性。文中以某城市四等GPS控制网为例,探讨以城市CORS站分析GPS控制网起算点兼容性,并得到成功应用。

| Abstract: | Different levels of control points at different time or layout may hide a large error .If the error is larger as the starting point it will distort the accuracy of GPS measurements which seriously affects the reliability of the results .A city with four GPS control network is taken as the example ,the urban CORS stations with starting point of GPS control network compatibility are analyzed ,and have been successfully applied . |
