| 摘 要： | 为综合应用不同参考坐标系中的测量成果，必须实现不同参考坐标系的统一。本文研究了回归模型在坐标转换中的应用，结合坐标转换实际提出并采用了多项式回归及逐次剔除的回归方法。文中介绍了坐标转换软件ＲＣＴ的主要功能，应用该软件计算了 １９５４年北京坐标系至 １９８０ＮＮＳＳ（ＢＥ）的最优回归转换模型。

| Abstract: | It is necessary to unify different geodetic reference systems in order to realize comprehensive utilization of surveying achievement in different systems. This paper discusses the use of the regression model in coordinate transformation. The way of polynomial regression and getting rid of regression coefficient step by step is presented and employed. The regression coordinate transformation models between 1954 Beijing Coordinate System and the Doppler satel- lite positioning system are given in the paper. |
