In 1993, it estimated that the cost of a kit to receive navigation signals from existing satellites was $40,000 for each bomb.

"Everything that moves will use a navigation signal - airplanes, trains, yachts, people, rockets, valuable animals and favorite pets."

The navigation signal allows the equipment to find a magnetic bearing from the station to the aircraft.

Computer, fax, and satellite-delivered navigation signals will all be standard in any car built after 2001.

They knowingly attempted to land using an inappropriate navigation signal and ignored alarms warning them of an impending crash.

Meaconing is the interception and rebroadcast of navigation signals.

However, communications transmitters are often used to transmit navigation signals.

Other specialist staff were navigation, signals and intelligence personnel.

But there is no navigation signal from the surface.

The satellite payloads would consist of atomic clocks and electronic equipment to generate the navigation signals.
