Abstract:
A method of determining the position of geostationary satellites by means of signals of at least one navigation satellite, comprising the steps of:determining data concerning the transit times of the signals from the at least one navigation satellite to the geostationary satellite by a device of the geostationary satellite, determining navigation data of the at least one navigation satellite by a navigation device which is independent of the at least one navigation satellite as well as of the geostationary satellite, determining data concerning the system time of the at least one navigation satellite by a navigation device which is independent of the at least one navigation satellite as well as of the geostationary satellite, providing data exchange of the navigation and the data concerning the system time or of the data concerning the transit times between the geostationary satellite and the navigation device; and determining position data of the geostationary satellite from the transit times, the navigation data as well as the system time of the at least one navigation satellite within the geosynchronous satellite or within the navigation device.
