  • Method of determining the position of geostationary satellites by transit time measurements of satellite navigation signals
    Patent number: 6683565
    Abstract: A method of determining the position of geostationary satellites by means of signals of at least one navigation satellite. A determination is made of 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, and a determination is made of navigation data of the at least one navigation satellite by an independent navigation device. A determination is made of data concerning the system time of the at least one navigation satellite by an independent navigation device, and a data exchange occurs between the geostationary satellite and the navigation device in order to determine 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.
