telemetry te·lem·e·try (tə-lěm’ĭ-trē)
n.
The science and technology of automatic measurement and transmission of data by radio or other means from remote sources to receiving stations for recording and analysis.
telemetry
(tə-lěm’ĭ-trē)
The measurement of data at a remote source and transmission of the data (typically by radio) to a monitoring station. Telemetry is used, for example, to track the movements of wild animals that have been tagged with radio transmitters, and to transmit meteorological data from weather balloons to weather stations.
telemetry [(tuh-lem-uh-tree)]

Automatic measurement and transmission of data or information by such means as wire or (more commonly today) microwave relays from the source to a distant receiver.

Note: Satellites transmit their data by telemetry.
