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.
Claims19
A detection system, comprising:
- a fixed-position transmitter for digitally transmitting a data packet including angle information associated with the transmitter;
- and
- a mobile unit including a receiver for receiving the transmitted data packet, wherein
- 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,
- determine new angle information from the non-identical angle information in the plurality of data packets, and
- determine a location of the mobile unit relative to the transmitter using the new angle information.
A mobile unit for receiving a transmitted data packet including angle information from a fixed-position transmitter, wherein
- 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 associated with the single transmitter,
- determine new angle information from the non-identical angle information in the plurality of data packets, and
- determine a location of the mobile unit relative to the transmitter using the new angle information.
A method for determining a location of a mobile unit, comprising the steps of:
- receiving a transmitted data packet including angle information from a fixed-position transmitter and associated with the transmitter;
- detecting a plurality of data packets from a single transmitter, the plurality of data packets including non-identical angle information associated with the single transmitter,
- determining new angle information from the non-identical angle information in the plurality of data packets, and
- determining a location of the mobile unit relative to the transmitter using the new angle information.
A computer program product comprising a computer useable medium including a computer readable program, wherein the computer readable program when executed on a computer causes a location system to determine a location of a mobile unit, comprising the steps of:
- receiving a transmitted data packet including angle information from a fixed-position transmitter and associated with the transmitter;
- detecting a plurality of data packets from a single transmitter, the plurality of data packets including non-identical angle information,
- determining new angle information from the non-identical angle information in the plurality of data packets, and
- determining a location of the mobile unit relative to the transmitter using the new angle information.
