摘　　要：将高斯投影计算的原始公式编制成程序,并在程序中预先定义几个常用椭球以及它们的相关参数;同时将程序分为单点模式和批量模式,并打开一个自定义椭球接口来满足用户的需要。通过算例与工程应用软件南方CASS 8.0版本坐标换带模块进行对比分析,结果证明该程序是可靠的,能够满足日常测量工作的基本需要。The program was based on the formula of Gauss projection, and pre-defined several commonly used ellipsoidand their related parameters in the program.The program contains two modes： single model and batch mode, and has a custom ellipsoid interface tomeet the needs of its users.By the comparison with calculation results of commercial software-CASS8.0, it is believed that the program is reliable can meet the basic requirements of daily measurements.

关 键 词：坐标转换 高斯投影 正反算 换带计算
