GPS平面控制网成果转换为地方坐标系或者其他国家坐标系，必须给定相应的约束条件进行约束平差，起算点的兼容性分析是其得出良好平差成果的前提条件。本文主要通过直观分析法、单位权方差假设检验法、尺度参数法阐述了起算点兼容性分析的理论基础，并通过实例论证三种兼容性分析法的可行性、一致性，对相关工程中起算点的兼容性分析具有一定的参考价值。

GPS Control Network plane coordinate system converts to local coordinate systems or other country coordinate systems ,there must be given appropriate constraints for constrained adjustment ,and the compatibility analysis of starting control points is the precon-ditions of good results .This paper mainly through visual analysis ,hypothesis testing method variance of unit weight ,the scale parameter method describes the theoretical basis for the analysis of the compatibility of the starting control points , and through three examples demonstrate the feasibility of the compatibility analysis .As a conclusion ,compatibility analysis of starting control points has certain ref-erence value to the relevant projects .
