1. A method for determining a geographical position of a rotor with a rotor blade of a wind turbine, the method comprising:
receiving at least two items of first position data from a GNSS (Global navigation satellite system) receiver arranged in the rotor blade, wherein the at least two items of first position data represent two different horizontal positions of the GNSS receiver, and determining a first rotor orientation based on the first position data;
receiving at least two items of second position data from the GNSS receiver and determining a second rotor orientation based on the second position data, wherein the second rotor orientation differs from the first rotor orientation; and
determining the geographical position of the rotor based on the first rotor orientation and the second rotor orientation.
