Frequentis has delivered its IP-based voice communication system (VCS) to AVINOR, the Norwegian air navigation service provider (ANSP), to power the country's first remote tower system.
The new system will initially be assessed by AVINOR in collaboration with Frequentis and all SESAR project partners over the next month to test the possibility of providing ATC service at an airport from a centre situated hundreds of kilometres away.
The validation exercise will also provide effective feedback for designing future VCS devices that can serve instantaneous ATC operations at several remote aerodromes from a single centralised controller working position (CWP).
Based on the VCS3020X platform, the new VCS system complies with EUROCAE Working Group 67's voice over internet protocol (VoIP) in air traffic management (ATM) standards and enables the dynamic interconnection of multiple airports with a remote tower centre.
The VCS3020X is an integrated voice and data switch for radio, telephone and intercom incorporated in a modular and scalable architecture.
The system also allows the addition of more airports as per SESAR's scheduled plans for 2013.
Moving from local to remote tower operations transforms the current static configuration of ATC equipment, wherein each aerodrome has its interconnected controller working positions and radios.
Aerodromes may also be operated from diverse working positions at different geographic locations and can also be altered during the course of a day through the dynamic routing capability of IP networks.
The system enables migration from time-division multiplexing (TDM) to IP operator position links via parallel support of TDM-based and structured or point-to-point Ethernet/IP-links.
Frequentis has also performed multi-tower simulations for deploying the voice communication system for the remote tower concept.
