Telemetry is used to obtain data on the internal functioning of missiles, rockets, unmanned planes, satellites, and probes, providing data on such factors as position, altitude, and speed as well as conditions like temperature, air pressure, wind speed, and radiation. Weather forecasters rely on telemetry to map weather patterns.
