Automatic Packet Reporting System
APRS allows users to view where other stations are in relation to them, commonly on a map. Though APRS is not limited to position data, position data is used most.
Practical applications for this mode might include Skywarn storm spotting operations allow net control operators to look at a screen and see where a spotter is instead of calling the spotter on what could be a very busy net. All of this happens very quickly -- many times under two minutes.
I have for your enjoyment, listed the position of my stations.
