The EYTraker unit was designed as part of a new generation of APRS tracking devices that will add to the growing number of units that currently support live and realtime APRS tracking. The unit is different from the current tracking units available from various sources, based on the fact that the tracking unit does not use conventional HAM frequency RF technology, but rather utilises the GSM band, in particular the GPRS functionality, of the GSM system to relay APRS packets.

The EYTraker unit incorporates a complete realtime APRS tracking solution by providing the user with an onboard GPS device, a Quad band OEM GSM module with SIM card holder and an integrated micro-controlled management system to control the OEM modules.

There is no need for any additional radio or GPS equipment, the EYTraker does all the tracking work for you, in a small form factor, directly onto UIView or any APRS compatible software systems, ANYWHERE in South Africa!

The tracking unit will operate accross South Africa where there is GSM coverage. This fact being the big advantage of this tracking Unit, there is no need to be within the range of an APRS digi peater for this unit to function and relay position.

Please refer to the links on the left for more information on what the EYTraker looks like, what it can do and how to get hold of your own unit.

EYTraker PIC software is written using PROTON IDE from Crownhill running on a PIC 18F252.

***** Please Note: EYTraker is only available to Licenced Radio Amateurs *****
