Satellite terminal with sleep mode

摘要

A remote ground terminal for transmitting a modulated data signal to a satellite. The remote ground terminal comprises a source of data signals, a demodulator for receiving a data signal and coupling the data signal to a transmitter, and for producing a power control signal during the period the data signal is present at an input of the demodulator. The power control signal is coupled to the transmitter and controls the operation of the transmitter such that the transmitter only receives power when the demodulator produces the power control signal. During the period the transmitter receives power, it functions to provide and modulate a carrier signal in accordance with the data signal received from the source of data signals.
