Field: Measurement (Instruments)
Classification: CPC F  G  Y | IPC F  G

Claim 0:
1. A method of determining a position of a yaw axis of a wind turbine including a nacelle that carries a global navigation satellite system (GNSS) sensor, comprising:
yawing the nacelle through a series of yaw angles;
measuring the position of the GNSS sensor at each yaw angle of the series of yaw angles;
recording each position measurement to define a series of positions;
processing 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
determining the position of the yaw axis based on the position of the GNSS sensor and the radius of the circle.
