Abstract
A tethered vehicle such as a missile system comprises a tethered vehicle body having a control system and propulsion system therein, a control station for the tethered vehicle located outside of the tethered vehicle body, and an optical fiber data link extending from the tethered vehicle control system to the control station. The tethered vehicle system further includes a GPS positioning system for the tethered vehicle, which comprises a positioning signal receiving antenna mounted in the tethered vehicle, and a positioning signal amplifier mounted in the tethered vehicle, which receives a positioning signal from the antenna and produces an amplified positioning signal. A transmitter transmits the amplified positioning signal into the optical fiber data link at its end within the tethered vehicle, and a receiver receives the amplified positioning signal from the optical fiber data link at its end at the control station. A signal processor analyzes the amplifier positioning signal received from the receiver. The signal processor is located at the control station. Preferably, there is imposed a time-shift correction to the positioning signal to negate the effect of the separation between the antenna and the signal processor.
