A method of determining an angular position of a nacelle of a wind turbine is provided, the nacelle being rotatably mounted at an upper end of a tower, the lower end of the tower being supported by a foundation. The method includes obtaining and storing a foundation angular position corresponding to a foundation reference point, the foundation angular position being relative to true north, determining a tower angular position based on the foundation angular position and information indicative of an angular relation between foundation and tower, the tower angular position corresponding to a tower reference point, receiving an encoder signal indicative of the angular position of the nacelle, detecting that a sensor mounted to the nacelle is the encoder signal such that the indicated angular position of the nacelle corresponds to the tower angular position. Furthermore, a controller for a wind turbine, a wind turbine, and a wind farm are provided.
