What is a space telecommand station?

Under FCC rules, a 'space telecommand station' is an earth-based amateur station designed specifically to control a space station, such as an orbiting amateur satellite. Its primary function is to transmit 'telecommands,' which are one-way signals that initiate, modify, or terminate the functions of the remote spacecraft. It is important to distinguish the control station from the space station itself. A space station is the equipment located more than 50 kilometers above the Earth's surface. The telecommand station is the station on the ground giving the orders. Distractors in this question often try to confuse the control station with a general Earth station (which simply communicates through a satellite) or a station that just receives telemetry data. Remember that 'command' implies actively controlling the remote device.
