First Claim
Patent Images
1. A remote synchronizing station, including:
- a) a receiver configured to receive signals from a base station, the time at which signals are transmitted from the base station and the transmission delay being known values;
b) a clock, synchronized with clocks present in each of the base stations;
c) processing circuitry, coupled to the receiver and to the clock, configured to;
i) measure the time of arrival of signals from the base station;
ii) calculate the transmission delay as the difference between the time of arrival and the time of transmission of signals transmitted from the base station; and
iii) calculate the difference between the calculated transmission delay and the known transmission delay.

Abstract
A method and apparatus for determining any offset between the timing of a communication base station and the timing of a GPS constellation using a remote synchronization station at which the timing of a base station can be measured and compared with known timing to determine an offset.
