Method and apparatus for an independent positioning system and augmentation of GPS
First Claim
Patent Images
1. An apparatus comprising:
- a transceiver to receive a first set of codes from multiple separate transmitters via a short-range wireless Bluetooth™
communications standard, the transceiver to generate a second code; and
a correlator on the transceiver to uses the first set of codes and the second code to find a distance between the transceiver and the transmitter, the correlator using the distance to determine a position of the transceiver relative to the transmitter.

Abstract
A method and an apparatus for a positioning system and augmentation of a global positioning system (GPS) are provided. The system includes at least one transmitter and at least one transceiver. The transceiver is able to calculate a position of the transceiver relative to the transmitter using information sent by the transmitter to the transceiver.

10. A system comprising:
-
a set of transmitters to transmit a first set of codes corresponding to the transmitters via a short-range wireless Bluetooth™
communications standard;
a transceiver having a radio frequency (RF) unit with a radio to receive the first set of codes, the transceiver to generate a second code;
a baseband processing unit on the transceiver, the baseband processing unit to process a noise code received from a satellite in a global positioning system (GPS); and
a correlator on the transceiver to uses the first set of codes and the second code to find a distance between the transceiver and the transmitter, the correlator to use the distance to determine a position of the transceiver relative to the transmitters, and the correlator to determine a second distance between the transceiver and the satellite in order to determine a second position of the transceiver relative to the satellite. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method comprising:
-
sending a first set of codes from a set of transmitters to a transceiver via a short-range wireless Bluetooth™
communications standard;
generating a second code to correspond to the first set of codes;
comparing the first code with the second code;
calculating a distance between the transmitters and the transceiver; and
determining a position of the transceiver relative to the transmitters using the calculated distance between the transmitter and the transceiver. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
