Claim 0:
1. A method of determining an orientation of a nacelle of a wind turbine, wherein the nacelle carries a Global Navigation Satellite System (GNSS) sensor, the method comprising:
yawing the nacelle between a series of orientations;
at each orientation of the series of orientations, measuring a calibration position with the GNSS sensor to generate a series of calibration positions each associated with a respective orientation of the series of orientations;
defining locus data based on the series of calibration positions and their respective orientations;
storing the locus data;
after storing the locus data, measuring a new position with the GNSS sensor; and
determining the orientation of the nacelle on the basis of the stored locus data and the new position.
