Claim 10:
11. 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 through a series of yaw angles;
measure a position of the GNSS sensor at each yaw angle of the series of yaw angles;
record each position measurement to define a series of positions;
process the series of positions to obtain locus data that defines a circle having a radius which is a distance between the GNSS and the yaw axis; and
determine the position of a yaw axis based on the position of the GNSS sensor and the radius of the circle.
