摘要
描述了坐标系统的概念及不同坐标系统的转换模型,以GARM IN手持GPS为例,说明各转换参数的含义、求解方法并给出1954年北京坐标系和1980西安坐标系下转换参数的经验值,对手持GPS进行误差分析及转换参数的适用范围。
The article describes the conception of coordinate system and the transformation model of the different coordinate systems. Taking GARMIN handheld GPS as an exam ple, the article illustrates the meanings and solving methods of various transformation parameters, and gives the empirical values of transformation parameters in 1954 Beijing and 1980 Xi’an Coordinate Systems. The handheld GPS is analyzed by the error and the suitable range of transformation parameter.
