telemetry

Telemetry is the wireless transmission and reception of measured quantities for the purpose of remotely monitoring environmental conditions or equipment parameters. The term is also used in reference to the signals containing such data.

Telemetry is used with satellite s, space probes, and mobile robot s. Telemetry is employed in manned spacecraft, such as the Space Shuttle and the International Space Station (ISS), to monitor the physical condition of astronauts and to ensure the maintenance of a proper working environment for them. Telemetry is also used with the Hubble Space Telescope (HST).

A telemetry transmitter consists of a set of measuring instruments, an encoder that translates instrument readings into analog or digital signals, a modulator, and a wireless transmitter with an antenna. A telemetry receiver consists of an antenna, a set of radio-frequency ( RF ) amplifiers, a demodulator, and recording devices. A computer can be used to process and store received information.
