摘要
介绍如何利用GPS水准点加强和改善天文重力水准网的原理、方法及实现的途径。以单线推进路线为例 ,一般证明GPS水准点的控制作用。还着重讨论并验证间接平差方法的有效性 ,能够满足当前需要。
The paper introduces the theory, methods and ways to be realized upon how to strengthen and improve the leveling network of astronomy and gravity with the application of GPS leveling point. Besides the control function of GPS leveling point, generally proved by the example of single line pushing the way, the paper mainly discusses and testifies the validity of the indirect adjustment, which can satisfy the present uses.
