APRS is every event coordinator’s dream tool. Being able to visually track resources without the typical “where are you?” call expedites dispatching of these resources.
APRS combines a GPS with a TNC (radio modem) and a VHF radio to broadcast the location of the unit. There are also smart phone based apps available for a few dollars.
The picture on the right is from a smartphone while on the course. The event layout is clearly defined with aid stations marked and some of the roving units.
The following pages will give much more information. This is a great tool!
