Telemetering

A method used to transmit quantitative information from a vehicle in flight to a station on the ground where this information can be used. Airplanes, missiles, rockets, and other types of complex devices are equipped with many different types of instruments that measure movement, pressure, temperature, acceleration, and strain. The output from these instruments is coded and transmitted to flight test stations on the ground. Here it is decoded and given to the engineers in a form they can use to determine what is happening to the vehicle in flight.
