Descrizione prodotto

The vehicular system extends traffic control to land vehicles on the airport grounds. VMT(Vehicular Mode S Transponder) optimizes the management of mobile vehicles at the airport and minimizes the risk of accidents with the continuous tracking of moving vehicles. The VMT system creates a real data link between the vehicle and the control tower, with the possibility of bidirectionally transferring even custom messages between network elements, exploiting the selectivity of the "Mode S" technology. VMT is a Mode S transponder that can be installed in a simple and non-invasive way on service and rescue vehicles throughout the airports: it identifies the individual moving vehicles and sends their position to the sensors of the MLAT or ADS-B systems present at the airport. VMT is a device capable of transmitting and receiving "Mode S" pulses and thus encoding data for avionics control systems and decoding the data of vehicles/aircraft equipped with transponders according to ICAO regulations.

VMT naturally integrates with the surveillance and ATC (Air Traffic Control) system, both based on ADS-B technology and on multilateration (MLAT), also for vehicles moving on the airport grounds such as means of transport for passengers, goods, service vehicles, deicing,etc... The transponder integrates a dedicated "Mode S" transmitter and receiver, a GPS receiver, a radio frequency front-end and a latest-generation digital processing unit. The VMT system has a local communication interface (HMI) with a "touch screen" display to be placed on the vehicle to display the positions of land and avionics vehicles in the vicinity of the mobile vehicle equipped with a VMT transponder. The system allows you to achieve a function similar to a navigator, reducing the risk of collision even in conditions of poor visibility. The device can also display information content of messages, even custom, that the control tower sends to the vehicles in motion through group or selective messages.
