Next generation satellite navigation systems

    Research output: Book/ReportReport


    The report gives a brief introduction to the existing and planned global satellite navigation and augmentation systems. It addresses their current status and future modernisation / development plans in addition to their basic architecture. The report also presents the idea behind pseudolites and the challenges related to them. Furthermore, the convergence of global satellite navigation systems and wireless communication devices is covered by explaining the concepts of A-GPS and A-GNSS. The two architectural approaches to implement A-GPS are discussed as well as the modifications required to the cellular network specifications introduced by next generation GNSSs. Information sources related to satellite navigation and positioning including universities, research institutes, organizations, agencies, magazines and relevant projects are also collected to this document in order to create a knowledge base of the research field. Finally, issues that affect the evolution of satellite based positioning are being discussed.
