  • In this paper, a method of continuously operating reference station (CORS) normal height service based on grid is proposed. By modifying the data generation and broadcast mode of the traditional virtual reference station technology, the grid virtual observation data is generated through the way of grid division, and the elevation anomaly correction is added to the grid virtual observation data, so as to realize real-time normal height measurement. The method provides users with real-time normal height measurement results without reducing their accuracy, which can enhance the service capability of the CORS system and can provide reference for the construction of CORS systems in other provinces and municipalities.
