Telemetry is the transmission of measured values ​​of a sensor, at the measuring location, to a spatially separated location. At the receiving site, the measured values ​​are collected, recorded and evaluated. Telemetry can find its use in a wide variety of fields, e.g. collecting weather data, traffic information, space technology, aircraft, vehicles or observing wildlife migration. It is even possible via a remote control to send commands to the sensor, which will follow these instructions and send the data back to the receiving point. In satellite telemetry, the sensor receives GPS signals from the moving object, from which it can calculate its current position, altitude and speed and send it to the receiving station via a satellite.
