Abstract:
Determination of one or more timing (phase) and/or frequency corrections to be made to a local time base of a receiver device to synchronize the local time base with the time of GPS or other highly accurate time base. Timing packets from one or more grandmaster devices whose time bases are substantially the same as that of GPS or the like and/or positioning system signals (e.g., GPS signals) directly from a positioning system are received and manipulated to determine the timing and/or frequency corrections. The corrected time base may be used to assist in acquiring such positioning signals to allow for higher accuracy correction and/or for downstream communication operation. The present utilities are advantageous such as when a sufficient number of channels (e.g., four) from the receiver device to positioning system satellites are unavailable to synchronize the local time base to the GPS or other accurate time base.

Claim (Index 16):
The method of  claim 15 , wherein the manipulating includes:\n obtaining, for a first message sent from the master device to the slave device, a first time stamp indicating a first time that the first message left the master device and a second time stamp indicating a second time that the first message arrived at the slave device; and obtaining, for a second message sent from the slave device to the master device, a third time stamp indicating a third time that the second message left the slave device and a fourth time stamp indicating a fourth time that the second message arrived at the master device; wherein the slave device time offset is half of the difference between i) the difference between second and first times and ii) the difference between the fourth and third times.
