A three-way communication system between a scientific balloon, aircraft, and ground tracking station is described. The balloon payload, which flies at an altitude of 40 km, is used as an active repeater. The system uses links already existing in this kind of flight: telecommand, telemetry, and radio localization. The signal from the ground station comes to the balloon through the telecommand link, is sent to the aircraft through the radio localization link. The signal from the aircraft comes to the balloon through the telecommand link and is sent to the ground station through the telemetry link. Aircraft and ground station use a normal VHF communication link.
