Product description
The vehicle Transponder operates in accordance with the ICAO standard for VDL Mode 4 digital radio link.
It is the only standardised data link that is also suitable for time-critical applications and is characterized by very high delivery probability from the unique self-organized TDMA VHF data link. Its FM modulation scheme (GFSK) gives the data link long range at low power including very good transmission characteristics on ground, e.g. at airports.
The transponder is an important component of the Airport Organiser system through its ability to transmit and share information in real time, enabling collaborative decision making (CDM).
Information from the airport database is interfaced to the system and distributed to all users as Information Broadcast (INFO-B). Automatic Dependent Surveillance Broadcast (ADS-B) is provided for positioning and identification of all ground movements.
The equipment features applications for task assignment and vehicle coordination in ground handling as well as surveillance, routing, guidance and control for the highest level of operation in Advanced Surface Movement Guidance and Control Systems (A-SMGCS).
