TrakNet uses the 1200 baud Amateur PACSATs (AO-16, LO-19 and IO-26) for Live, Real-Time mobile position/status and messaging. Using these existing birds for this application can provide hundreds of mobile operators an essential channel for emergency or priority traffic using nothing but their normal 2m FM mobile radio and a laptop sound card or a $3 modified normal packet TAPR-2 TNC. Communications can consist of any viable UI packet or APRS status/position reporting packets digipeated by the satellite to a few nationwide downlink sites. These sites would forward the packets on existing HF and VHF networks and the worldwide APRServe Internet system.
