Abstract
A detection system includes a fixed-position transmitter and a mobile unit. The transmitter digitally transmits a data packet including angle information associated with the transmitter, and the mobile unit includes a receiver for receiving the transmitted data packet. The mobile unit is configured to detect a plurality of data packets from a single transmitter, the plurality of data packets including non-identical angle information. The mobile also determines new angle information from the non-identical angle information in the plurality of data packets and determines a location of the mobile unit relative to the transmitter using the new angle information. Also, the mobile unit is configured to indicate information associated with the determined location to a user.
