Abstract: A technique for measuring yaw (left-right direction) of a device includes obtaining a first measurement of an orientation of the device relative to a local magnetic frame of reference (FoR) and a second measurement of the orientation of the device relative to a spatial FoR, with both measurements made while the device is disposed at a known location and in the same orientation. The technique further includes computing an offset between the two measurements and storing the offset in connection with the known location. When the device later returns to the same location, the yaw direction of the device is determined based on acquiring a new measurement of the device's orientation relative to the local magnetic FoR and applying the offset as a correction.
