Does anyone know what underlying technologies they are using? Anything opensource server or client side? What types of hardware do they use in the vehicles to send the GPS info?
These use an off the shelf telematics system from webfleet or masternaut (it's gps for location, vehicle data connection for odometer and speed etc and 3g card for data signal) that send data back to the telematics database.
There's the a public API to call to get most recent position or all route. We used the public API to grab positions and display on a map.
