To provide correction data for determining position, first position data are determined and/or made available to a vehicle depending on an incoming Global Navigation Satellite System (GNSS) signal, the vehicle having a GNSS receiver or a differential GNSS (DGNSS) receiver for receiving the incoming GNSS signal, and the first position data being determined when the vehicle is in a charging position at a predefined charging station. Second position data are also determined and/or made available, the second position data including information which is representative of a global position of the predefined charging station. Correction data is determined depending on the first position data and the second position data. The correction data is made available to at least one further device to determine the position of the at least one further device.

Method for providing correction data for determining position

A method for determining the position of a charging station for wirelessly transferring electric energy to a vehicle, wherein the charging station comprises a ground unit with a primary coil configured to generate an electromagnetic charging field for transferring electric energy to the vehicle, and wherein the vehicle comprises a receiving unit of a satellite positioning system and a secondary coil in the vehicle underbody, comprises performing, by the receiving unit of the vehicle, a plurality of position determination operations for at least part of the duration of a charging process during which the vehicle is arranged with respect to the ground unit such that the secondary coil of the vehicle has a predefined positional relationship with respect to the primary coil of the ground unit. The method also includes determining spatial coordinates of the receiving unit of the vehicle from the plurality of position determination operations, and inferring spatial coordinates of the primary coil of the ground unit from the known position of the receiving unit relative to the secondary coil in the vehicle.
