NAVCOM system architecture

The main task of the NAVCOM project is the integration of a GPS/EGNOS receiver into an existing TETRAPOL mobile communication unit. This Integrated Terminal will supply the actual and valorised position information via the TETRAPOL communication network to an AVL Server. A user is able to track and guide several IT's on an AVL display and communicate with them via the voice and data channel of the TETRAPOL system. The navigation module is able to acquire assisted GPS and assisted EGNOS information via the communication system in case that the clear view to the satellites is obstructed.
