Yuanxi Yang, Mingquan Lu, HAN Chunhao · DOAJ (DOAJ: Directory of Open Access Journals) · 2016
Compatibility and interoperability of GNSS are the hot research issues in international satellite navigation field. It is a requirement for integrated multi GNSS navigation and positioning. The basic concepts of the compatibility and interoperability are introduced and the trend of the interoperability among the GNSS providers is discussed. The status and problems of the frequency interoperability of GPS, BeiDou(BDS), GLONASS and Galileo are analyzed. It is pointed that the frequency interoperability problems will affect the manufacturers and multi GNSS users. The influences of the interoperability problems of the reference coordinate systems are not only resulted from the definitions and realizations of the reference coordinate systems but also from the maintenance and update strategies of the reference systems. The effects of the time datum interoperability and corresponding resolving strategies are also discussed. The influences of the interoperability problems of GNSS are summarized.
