Abstract: A system for synchronizing stations in a communications network comprising: at least one airborne or space-based vehicle; and at least two stations, each station having receiver means in data communication with the at least one airborne or space-based vehicle and control means in data communication with the receiver means and in control communication with a communication means. When each receiver means receives a synchronization signal from the at least one airborne or space-based vehicle each receiver means forwards the synchronization signal to its respective control means. The respective control means processes the synchronization signal to determine the operational frequency required by its respective communication means to maintain or establish communication with the other station. The respective control means also operates to control its respective communication means to change to the determined operational frequency.

Abstract: A system for synchronising stations in a communications network comprising: at least one airborne or space-based vehicle; and at least two stations, each station having receiver means in data communication with the at least one airborne or space-based vehicle and control means in data communication with the receiver means and in control communication with a communication means. When each receiver means receives a synchronisation signal from the at least one airborne or space-based vehicle each receiver means forwards the synchronisation signal to its respective control means. The respective control means processes the synchronisation signal to determine the operational frequency required by its respective communication means to maintain or establish communication with the other station. The respective control means also operates to control its respective communication means to change to the determined operational frequency.

Abstract: Apparatus for attaching a cable terminal to a ferrule using a snap ring to chieve a rotatable connection wherein one jaw of the apparatus supports the terminal, a second jaw supports the ferrule, and an intermediate third jaw supports and compresses the snap ring. With the snap ring initially mounted on the terminal, closing the jaws together compresses the snap ring so that the terminal can be fully inserted into the ferrule until the snap ring is captured within the ferrule and completing the connection.
