Product information


VoIP based VCS

Complying with international standars for Air Traffic Control and being the 5th generation of the product with nearly 40 years in the market, the ULISES V5000i manages critical ground/air and ground/ground communications for air traffic control operators in every environment.

DF Núcleo, which currently has close to 85% of market share in Spanish Airports and counts with successful experience in three continents, has an established and more than proven path of providing an outstanding performance at an efficient investment cost.


VoIP Communication Gateway

Acting as a bridge between VoIP based systems and those based on analogic/digital technology, managing both legacy and VoIP radios and telephones, the ULISES G5000i optimizes the amortization and life cycle of the installed equipment set already installed.

Currently, DF Núcleo is executing the migration to VoIP of ENAIRE’s Aeronautical Navigation Data Network (REDAN), a nationwide project in Spain that includes almost 100 sites.


Multiprotocol Test Equipment

The system, designed in collaboration with ENAIRE, monitors and analyses communication protocols, lines and VCS used in Air Traffic Control Centers, supporting international protocols.

Nowadays, the SIGNUM T50 is the only tool in the market capable of identifying failures and testing analogic and VoIP communication networks at the same time.

Mobile Air Traffic Control Tower

The Mobile TWR is capable of providing the same capabilities of a fixed TWR, providing a solution for emergencies, technological improvements of the latter and it could even be used as a simulator operating simultaneously with the tower.

It includes: VoIP VCS ULISES V5000i, ground/air radio communication equipment using VHF UHF and/or HF frequencies, voice and video recording systems, meteo systems, wireless and F.O. connection with the airport’s technical block, etc.
