Abstract

Un-differential correction distributed processing system and method based on a receiver of a reference station, in which main calculation tasks of conventional centralized data processing are transferred to the receiver of the reference station. The receiver of the reference station executes tasks of the PPP calculation, the PPP un-differential ambiguity fixing and the un-differential correction product generating via data interaction with servers. The client generates a relevant virtual un-differential correction by visiting a reference station area code address server and achieves PPP-RTK calculation under area augmentation. Load of server is greatly reduced, and problem of overload on relevant servers is solved; meanwhile, there is no need for the client to arrange a machine room of servers that needs specially-assigned person on duty, thus reducing user's maintenance work on the servers and saving costs. The reference station and client are not required to upload geographic coordinates precisely, and confidentiality is better.
