Claim 15:
16. A wind turbine comprising:
a tower;
a nacelle rotatably mounted on the tower;
a Global Navigation Satellite System (GNSS) sensor carried by the nacelle; and
a control system configured to:
yaw the nacelle between a series of orientations;
at each orientation of the series of orientations, measure 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;
define locus data based on the series of calibration positions measured by the GNSS sensor and their respective orientations;
store the locus data;
after storing the locus data, measure a new position with the GNSS sensor; and
determine an orientation of the nacelle on the basis of the stored locus data and the new position.
