Description |
Scientists use plastic balloons as a vehicle to carry their middle
atmosphere, Astronomy, Astrophysics and Astrobiology payloads to an
altitude where the atmospheric noises are less. Once the balloon is
air-borne we need to establish two way radio link between the air-borne
sub-systems and ground control system. Communication link between
air-borne to ground control is called Down link (Telemetry) and the
communication link in other direction is called Up-link (Tele-Command).
My talk covers Telemetry, Tele-Command and Safety sub-systems which are
used for conducting balloon flights.
