Abstract
A remote time calibrating system has a calibrating station with a reference time and a remote station having a local time, the local time having to be adjusted to coincide with the reference time. The calibrating station receives telemetry signals sent from the remote station, each of the telemetry signals including data indicating the local time of the remote station from which the telemetry signal is transmitted. Responsive to any first difference between the receive reference time and the local transmit time is detected and calculated by taking into account the signal propagation delay of the telemetry signal between the remote station and the calibrating station. Responsive thereto, the local time is calibrated at the remote station.
