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.

Abstract: A reference station transmitter based distributed processing system and method for zero-difference correction. The system and method transfer a main computation task in conventional centralized data processing to a reference station transmitter for completion; the reference station transmitter realizes tasks such as conventional PPP resolving, PPP zero-difference ambiguity fixation and zero-difference correction product generation via data interaction with a server; and a user end generates a relevant virtual zero-difference correction by accessing a reference station area code address server, so as to realize PPP-RTK resolving under regional enhancement.
