  • Satellite navigation
    Patent number: 6188958
    Abstract: A method for satellite navigation and, in particular, a method for DGNSS (Differential Global Navigation Satellite System) is provided. Separate differential corrections are generated in a reference station with at least one fixed-position GNSS receiving antenna, for code and phase measurement. If necessary, a combination of the differential corrections is also produced. The differential corrections are transmitted to an aircraft (with GNSS) which is approaching landing, for example, via a data radio transmission link. This then enables high-precision GNSS navigation, to the extent that landings can even be executed fully automatically.
