The positive reputation that SITTI has accumulated in the past years through the supply of several systems in the Far East region is further witnessed by the award of a new order through Samart Aviation Solutions Public Company Limited (SAV). The new order consists of two new VCSs (Voice Communication System) for the main airports in Cambodia:

  • NPPIA – New Phnom Penh International Airport
  • NSRIA – New Siem Reap International Airport

Both VCSs belong to the M800IP® family of MULTIFONO ® systems, which implement the latest provisions defined by the most recent international standards issued by the competent bodies, like the EUROCAE ED 137 standard. This latter defines the way the VOIP technology (Voice over IP) is used in the Air Traffic Control (ATC) field.

The end customer is the national ANSP, Cambodia Air Traffic Services (CATS) that is responsible for the proper handling of flights in the Cambodian airspace. Each system encompasses 4 controller working positions connected to a significant number of VOIP radio channels and telephone lines.

The systems are also equipped with radio and telephone gateways for interfacing analogue connections to the new VOIP based network. Best Signal Selection (BSS) modules allow proper management of distributed radio frequencies to present controllers the best received audio.

SITTI is a primary VCS manufacturer and supplier worldwide, capable of giving prompt and top edge solutions to Customer needs, both in the Civilian and Military fields. The leading edge, redundant, non-blocking architecture of the MULTIFONO® M800IP® provides flexibility and modularity for easy expansion and addition of further functionalities.


In the frame of a commercial cooperation with LEONARDO, SITTI is going to provide Malaysia with new VCSs (Voice Communication Systems) and Emergency Radio Access Devices. More specifically, the new installations are relevant to the Kuala Lumpur Air Traffic Control Centre (KL-ATCC), the local Disaster Recovery (DR) facility and the control tower at Subang.

The new VCS systems are the most technologically advanced solution available on the market, fully compliant to the latest international standard in the field of air management and control, especially focusing on EUROCAE ED 137. This document defines the rules and protocols to use VoIP (Voice over IP) in the air management context, all over the world.

The Main Operatioanl System (MOS) at Kuala Lumpur is the largest among the systems provided to Malaysia, with 52 new controller working positions (CWP), from which controllers have full and possibly simultaneous access to almost 400 radio channels and more than 100 analogue and SIP telephone lines. The Disaster Recovery system is used as a contingency system, in case for any reason the MOS is unavailable; it has the same interface capabilities and around 40 new CWPs.

Moreover all the existing SITTI TDM-VCS have been upgraded in order to be integrated to KL-ATCC with VoIP radio and telephone connections over MPLS network.

Besides the supply of the above mentioned VCSs, SITTI is also delivering a significant number of so-called Emergency Radio Access Devices (ERAD), as last resort resources for the access to remote transceivers. These devices are air traffic control terminals, designed by SITTI as a powerful, flexible and cost-effective solution to ensure continuity of radio and telephone communications in the event of an emergency. Thanks to its all-in-one architecture, it is completely independent of the existing VCS network and is able to guarantee reliable communication with remote devices, even if the main system is out of order.

ERAD consists of an integrated operative position and associated electro-acoustical devices (PTT, microphone, loudspeaker), giving access to communication features through a 7 inch touchscreen panel, through which the operator can connect to any local and remote radio and telephone device

Leonardo is among the top world players in Aerospace, Defense and Security. The company, through the joint venture AAT (Advanced Air Traffic Systems) and the Civil Aviation Authority Malaysia (CAAM), is responsible of the KL ATTCC (New Kuala Lumpur Air Traffic Control Centre) program, which aims to enhance the management of Malaysian airspace.


ENAV, the Italian Air Navigation Service Provider, decided to upgrade the services provided by the weather forecast offices and their related data repository. The target is to provide operators with a more efficient access procedure, thus giving them a better and more precise weather situation awareness.

The coordination of the upgrade activities has been awarded to SITTI, based on the well-grounded reputation as system integrator in different areas related to air traffic control and management. The integration of different information sources and data streams into a comprehensive system capable of presenting information in a coordinated manner to operators and controllers is in fact one of the strength point of SITTI.

This delicate operation has been accomplished according to the strict requirements set by ENAV, which has been asking for a very highly reliable hardware and software infrastructure, also comprising the centralized presentation of weather information collected at all remote Italian airports in real-time mode. The system includes a new teleconference architecture making use of a videowall system.

Among the many features made available by the provided integrated system, the following ones are especially significant to be mentioned:

  • Weather information stored for long periods (at least 6 months).
  • Forecast, satellite, radar, lightning data decoded and properly visualized
  • Creating and sending of appropriate messages (like METAR,TAF,TAD) to spread information to all stakeholders
  • VCS (Voice Communication System) upgrade for coping with the new connections and systems, including new ISDN Basic Rate connections

The challenging requirements driving this project have been fulfilled by SITTI with complete customer satisfaction, thus once more proving the capability of SITTI to present itself as a system integrator for complete and complex solutions in all fields where reliable, secure, configurable data and voice communications are required.


Pratica di Mare is an important military airfield close to Rome. This military air base hosts several services and functions used by the Italian Air Force (AM-Aeronautica Militare), and for this reason it accommodates a number of communication systems devoted to the interface to other remote military sites and remote radio stations.

The Pratica di Mare air force base is currently undergoing a renewal project with the aim at the modernisation of its infrastructure, especially for what concerns the management of the voice for air traffic control and coordination activities. The objective is to integrate all features and services into a single VCS (Voice Communication System) that guarantees proper response to present and future operational needs for air/ground and ground/ ground communications.

Leveraging on the long lasting and successful relationship with Aeronautica Militare, SITTI is giving its proactive contribution to this project that involves all services based in Pratica di Mare, from area air traffic control to the local airfield tower.

More specifically, SITTI will be providing the air base with server-based VCS solutions, belonging to the MULTIFONO® M800IP® family. This family of products is already installed at other air force bases and has proven its outstanding reliability and high performance characteristics. The positive return from other installations paved the way to the new supply. The new system provides the Customer with the same features and extremely high availability figures as the other similar systems deployed in Italy.

The system being installed at Pratica di Mare is based on a quad-based server installation, where all message handling, computation, signalling and voice switching are carried out by duplicated COTS servers dealing with radio and telephone connections. This innovative approach to integration of services permits having a system that can seamlessly switch from main to standby machines without affecting ongoing communications, while at the same time complying with all standard ED-137 VoIP (Voice over IP) requirements.

A further integration step is represented by MFT800 multi-functional terminals, which are being used by controllers to quickly acquire the information they require for getting situational awareness and promptly access the communication and service options made available to them.
