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. Astronauts on the space shuttle are monitored with telemetry that measures and transmits readings on their blood pressure, respiration, and heart rates. Similar kinds of telemetry are used by biologists to study animals in the wild and keep track of their populations and movements. Telemetry is also widely used in modern agriculture, often to regulate irrigation.
