Bottleneck Problems of LCORS and Feasibility of New Technologies

The construction of Continuously Operating Reference Stations/System(CORS) has shown the trend of "building to large-scale" and "service to whole real-time". According to China\´s CORS building momentum, the national Large-scale CORS (LCORS) will be established on the basis of the Regional-type CORS (RCORS) interconnected, and provides static and dynamic positioning services, based on the collection and distribution of multi-mode multi-frequency GNSS observation data. In this process, it is necessary to establish a rational mechanism for resource management and dynamic service, but the effective solution has not yet emerged. Through researching on the applications of grid computing technologies in the field of geosciencein field, especially in geodesy field, found that grid computing technology can effectively solve the some bottlenech problems, such as system interconnection and system heterogeneous, and so on. There is a large study space in the researching on the dynamic service mechanism of LCORS, based on the grid computing technologies.
