APRS has been often used to track weather balloons and unmanned telemetry flights. A small transmitter and a GPS are attached to the payload; various APRS stations can then log the flight path and broadcast the received information via Internet.
APRS has also been used by fixed stations to send periodic weather information (temperature, pressure, wind, humidity, precipitation, visibility) and by mobile stations to announce location and identify another frequency on which the mobile is accepting voice communications.
APRS can also be used to send short (typically one-line) text messages, although it affords no privacy to message content.
