| 摘 要： | 针对城市卫星导航定位连续运行参考站(CORS)系统中坐标转换参数和似大地水准面模型成果严格保密的规定，基于布尔莎七参数和双线性内插法，提出了一种通用的城市CORS系统实时加密转换方法，实现了城市地方坐标系平面和正常高成果的实时获取. 该方法在合肥市CORS (HFCORS)应用中得到了验证，可为城市CORS测绘基准的应用服务提供参考.

| Abstract: | Aiming at the strict confidentiality of coordinate transformation parameters and quasi geoid model results in urban satellite navigation and positioning continuous operation reference station (CORS) system, a general real-time encryption transformation method of urban CORS system is proposed based on bursa seven parameters and bilinear interpolation method, which realizes the real-time acquisition of plane and normal height results of urban local coordinate system This method has been verified in the application of CORS in Hefei city (HFCORS), and can provide reference for the application service of urban CORS surveying and mapping benchmark. |
