| 摘 要： | GPS静态测量技术已在交通、水利等领域得到广泛应用,但测量数据的同步环闭合差核验往往很难达到现行测量规范的限差要求。通过系统分析GPS静态测量中同步环闭合差的产生原因,认为现行测量规范中同步环闭合差的限差值可能存在一定问题,进一步尝试推求同步环闭合差的限差参考值,并结合具体的工程实例进行验证和说明。

| Abstract: | GPS static measuring technologies are widely applied in transport and hydraulic fields etc. In general, the synchronous loop closure error of measured data is hard to satisfy limit error requirements in current measurement standards. The cause of synchronous loop closure error in GPS static measurement is systematically analyzed. It is proposed that the above limit error value may be not accurate. Then the limit error reference value is further induced for synchronous loop closure error, which will be verified and illustrated by combining with project examples. |
