APRS is a simple idea. Take a piece of information, such as a short message, a GPS co-ordinate, a weather station output and using either hardware or software, send that information over the air through a transceiver and enable other radio users to receive that information, decode it and show it on their screen.

Its a very basic form of communication, but very powerful and highly useful during public service events and emergency communications.
