A space station, beacon station, or telecommand station✓Richtige Antwort
A local repeater or linked repeater station
A message forwarding station or automatically controlled digital station
All these choices are correct

Space stations, beacons and telecommand stations each have explicit permission to transmit one-way communications. Repeaters retransmit the two-way traffic of other stations rather than originating one-way transmissions, and message forwarding stations carry messages addressed to a recipient.
