坐标转换与区域似大地水准面在HSCORS中的应用研究

针对呼和浩特市连续运行参考站系统（简称HSCORS）中，结合呼和浩特市区域精化大地水准面模型成果。利用数据处理与控制中心隐蔽播发功能，为用户提供实时高精度三维地方直角坐标成果的方法进行了分析和研究。用成果证明该方法能够有效地解决用户使用时野外点校正、坐标转换、编程求参数等等繁琐工作，具有一定的实用价值。

Coordinate Transformation and Regional Geoid in the HSCORS Application Research

This paper aimed at Hohhot in the continuous operational reference station system （ hereinafter referred to as HSCORS）, combined with the Hohhot area elaboration geoid model, using the data processing and control center hid- den broadcast function, to provide users with real-time and high precision 3 d achievements of local rectangular coordi- nate method are analyzed and studied. Results show that the method can effectively solve the user when using field point correction, coordinate transformation parameters and so on tedious work, programming, has certain practical value.
