摘要
GPS控制测量时,要联测一些国家或地方坐标系下的点作为起算点,但联测的这些起算点兼容性不好将影响整个网的精度,因此我们在把联测点加入控制网平差时应该对对其兼容性进行分析,剔除它们中兼容性不好的点,提高控制网精度。介绍了几种兼容性分析方法,总结出几点体会。
In GPS control survey, the survey of a number of national or local coordinate system of points is taken as Fixed initial points, But if the compatibility of these Fixed initial points is poor, it will have an impact on the accuracy of the en- tire network, so we should analysis the compatibility of these points before adding them to control network. The poor compat- ibility of points should be got rid of to improve the accuracy of Control Network. The article describes several compatible ways to arrive at some suggestions.
