Abstract
A method for providing correction data for satellite navigation, includes determining the correction data using a plurality of state signals relating to the Earth's ionosphere, each of the state signals associated with one of a plurality of signals which have been received by an interface for a plurality of mobile satellite receivers, the plurality of mobile satellite receivers provided for satellite navigation. Each of the plurality of state signals identify a geographical position of an associated one of the plurality of mobile satellite receivers and an item of state information relating to the Earth's ionosphere which is determined using at least one satellite signal transmitted between at least one satellite and the associated one of the plurality of mobile satellite receivers. The correction data is transmitted to the at least one satellite and then transmitted from the at least one satellite.
