Automatic Position Reporting System
The clubs APRS (Automatic Position Reporting System) station is a TNC-2 connected to a VHF radio on the national APRS simplex channel of 144.39 MHz . Equipped within the TNC is the Unidigi™ software that permits any station to repeat and report the location of stations to all other stations on the frequency. The Digi node also sends the information to the Central Ohio "I" Gate which is then sent onto the Internet which in turn shows the stations on a real-time map at the web location www.findu.com
The links below on this web page better describe the nuts & bolts of the national APRS network and how the ISS (International Space Station) is involved. Basically any mobile equipped with a GPS, radio on 144.39 MHz and a TNC can be tracked anywhere in the US and several places abroad. The uses of the tracking system are many.
