On September 11, an important contract has been signed between the Vietnam Air Traffic Management Corporation (VATM) and SITTI for the supply of a new Voice Communication System (VCS) system. This contract (worth about 1.6 million euro) is part of the “Ho Chi Minh Air Traffic Control Centre – ATCC/HCM“ project which includes the “Supply and installation of VCCS voice communication and control system“.

The new contract signed in Ha Noi came after a harsh selection process of international vendors, during which both technical and financial proposals have been analysed by VATM, aiming at providing the Ho Chi Minh City Air Traffic Control Centre (ATCC) with one of the most important equipment needed for air traffic control (ATC). The contract envisages one main VCS system with 80 working positions, plus a backup/training one with further 70 working positions.

The VCS voice communication that will be supplied by SITTI will allow Vietnamese ATCOs to proactively, efficiently and effectively manage the air traffic flow over the vast airspace under their control, thus contributing to the overall flight safety in the area. The new system at ATCC/HCM will in fact ensure the provision of air navigation services for the Ho Chi Minh FIR (Flight Information Region).

At the signing ceremony, VATM was represented by Deputy General Director Ho Sy Tung, while SITTI representative was Mr. Gianluca Codega, Sales Director. Both expressed their satisfaction for the positive conclusion of the evaluation process and its finalisation.

This major project is an important development step for VATM, and SITTI is glad to be part of this process. With almost 80 years of experience in providing equipment systems for air traffic control, SITTI is grateful to VATM for its trust in the company as the supplier of the VCS system, that will contribute to ensuring safe and effective air traffic operations in the region thanks to its compliance to the tough technical requirements set, its proven high reliability and flexibility, meeting current operational needs and scalable to meet future operational needs.

The Kuala Lumpur International Airport (KLIA) is a very busy airport in the Far East, which SITTI has already provided a number of solutions for air traffic control. The Eastern and Western towers of this large airport require extensions for interfacing new radios, namely 19 radio receivers plus 18 radio transmitters.

SITTI will therefore supply all needed equipment for the proper handling of these new radio connections, also including BSS (Best Signal Selection) functions that automatically choose the best received audio from different receivers operating on the same frequency. All the new boards are envisaged to be physically installed in the already existing racks placed in the two towers, thus not requiring any additional space in the respective equipment rooms.

The extension is going to be installed in the next few months to cope with the agreed SAT time schedule, according to which all activities shall be completed by the end of next March.

The new boards are added to the existing VCS (Voice Communication System) without disruption of ongoing services, so that their smooth and seamless introduction will allow ATCOs to immediately access the new communication facilities without experiencing any outage of the system.

SITTI is honoured of announcing that the systems recently supplied to Vietnam have now become operative. With the important support of VATM (Vietnam Air Traffic Management Corporation), SITTI delivered a brand-new IP-based VCS (Voice Communication System) to SORATS (Southern Region Air Traffic Services Company).

This is the first time SITTI supplies such a large system to Vietnam. The new system, belonging to the MULTIFONO® renowned family of VCSs, has been installed at the ACC (Area Control Centre) in Ho Chi Minh, in the Southern part of the country. SITTI has been responsible for the supply, installation, configuration, setting to work, integration and commissioning of the Voice Communication System and its associated equipment, tools and services, with the fundamental support and help of the local company VATM.

The M800IP® system supplied includes 36 Controller Working Positions (CWPs) with full radio, telephone and intercom facilities to access a large number of analogue radio and telephone channels and lines. This system is natively ready to be expanded to also include VoIP (Voice over IP) links, by simply changing the system configuration through the Technical and Monitoring Control system (called MMS) being also part of the delivery.

The number of controllers utilizing the VCS can be seamlessly expanded at any time in the future; similarly, radio and telephone connections of any kind can be added without causing any system disruption. Main/Standby automatic switching modules and radio Best Signal Selection (BSS) boards complete the system, thus giving ATCOs (air traffic controller operators) the best-in-class facilities to properly and effectively manage the air traffic directed to or departing from Vietnam, or flying over it.

“This is the first time we supply such a large system to Vietnam. This makes us proud because of the recognition of the high quality standards of our products, once again testified by achievements like this.” – Mr. Panzeri, SITTI Program Manager said – “We are sure the end customer (SORATS) will benefit of the top-level reliability and expandability of the supplied system.”

Zhanjiang is a big city with more than 7 million people located on the Leizhou peninsula in the South of China, belonging to the Guangdong province. It is an important harbour on the South China Sea and industrial city with large commercial interests.

For the improvement and expansion of the local airport, SITTI has been awarded the supply of a brand new MULTIFONO^® M800IP^® Voice Communication Solution (VCS), through the very good work and capabilities of our local representative, Beijing XiDi Communication Technology Co., Ltd.

Over the past years, SITTI has been installing a large number of VCS systems throughout China. The new order witnesses the excellent reputation that our company has got in the Far East, thanks to its top level systems, capable of adapting themselves to many different environments and capable of managing the Air Traffic Control of small airfields as well as large ACC centres.

The new VCS has been installed at the local Zhanjiang International Airport for the improvement and increase of the traffic management capacity; the airport has become operative on March 24^th. It envisages a set of controller working positions, capable of interfacing both analogue and digital radios and telephone lines, with all the features and facilities available at larger installations.

This allows the system to get all benefits from the native flexibility of its MULTIFONO^® IP-based architecture, without losing the possibility of providing full access to all kinds of interfaces and lines. The system is fully complying with the most recent standards issued by EUROCAE in its ED-137, which defined the rules for the use of VoIP (Voice over IP) in the Air Traffic Control and Management fields.

A significant number of analogue and digital radios and telephone lines are interfaced to this system through dedicated gateway cards that convert signalling and voice according to the ED-137 provisions. This allows air traffic controllers to speak to pilots and other operators and make air traffic safer in their area of responsibility.

The new system is seamlessly expandable at any moment in time by simply adding new controller working positions and/or modules. Their configuration can be autonomously carried out by the local staff by means of the supervision and maintenance system, which is also part of the supply: they can be put into operation in a matter of minutes, thus significantly enhancing the air traffic control capabilities of Zhanjiang operators.

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.
