摘要/Abstract

摘要： 讨论了WGS-84坐标系统和地方坐标系统之间坐标转换的数学模型.研究了坐标转换数学模型的简化公式，在对其精度分析的基础上，对简化公式的适用性进行了论证.根据若干个已知点在两个坐标系统中的坐标值，利用最小二乘法拟合了回归曲面.提供了坐标转换的一种可行方法.

Abstract: Study about the transformation relationship among different coordinates systems has been made to solve the problems in the application of GPS. The precision of the simplified coordinates transformation formula has been analysed. It was shown that the rational simplification is necessary and it will help to enhance the efficiency of the GPS system, for example, the vehicle navigation and real-time monitoring systems. An example and a feasible method to solve the unkown parameter are provided.

Key words: GPS geodetic coordinates, Gauss projection, coordinates transformation, GPS geodetic coordinates, Gauss projection
