Abstract: Global navigation satellite system (GNSS) precise positioning service have been widely applied in various industries such as national defense construction, smart city, transportation, smart robot, unmanned aerial vehicle. The technology and service application of precise positioning continue to develop in recent years. First, this paper summarizes the research progress of precise positioning technologies represented by precise point positioning, precise point positioning with ambiguity resolution, and precise point positioning and real time kinematic in the aspect of multi-system and multi-frequency, atmospheric correction and ambiguity resolution. Second, it reviews the service capacity, scope and other aspects and long-term development plan of precise positioning service for the major satellite navigation systems. Then, the characteristics, service capabilities, and application progress of precise positioning service and technology provided by the mainstream commercial companies are discussed. Finally, it analyzes the challenges faced by GNSS precise positioning service, the development trends, and the future prospects.
