1. A method comprising:
receiving data packets from a personal meter associated with a user who is exposed to media through a media presentation device at a media exposure measurement location;
determining a mode of direction finding associated with the data packets;
determining, based on the mode of direction finding and quadrature signals extracted from the data packets, location data characterizing a location of the personal meter relative to the media presentation device at the media exposure measurement location; and
storing the location data with corresponding location timestamps.
