ASECNA, INEO E&S and SITTI for a safer sky

Posted on by sittadmin

ASECNA has recently awarded SITTI with a contract for the provision of 3 new Voice Communication Systems (VCS) for the capital cities of Burkina Faso, Congo Brazzaville and Niger. ASECNA (acronym for Agence pour la Sécurité de la Navigation Aérienne en Afrique et à Madagascar, i.e. the Agency for Air Navigation Safety in Africa and Madagascar) is an international public organization composed of 18 Member States. Created in 1959 and based in Dakar-Senegal, its mission is to provide air navigation services, aeronautical information services and aeronautical meteorology services to the airspace under the jurisdiction of its Member States and the oceanic airspace in central Atlantic Ocean, Gulf of Guinea and Indian Ocean.

The MULTIFONO® M800IP® system by SITTI has been chosen as the backup VCS system for equipping the Air Traffic Control facilities respectively in Ouagadougou, Brazzaville, Niamey. The three systems are quite similar to each other. They constitute of analogue connections to existing radios plus a standard ED-137 interface to the most recent technological VOIP solution; analogue telephone links to currently available lines are further enhanced by a standard VOIP telephone interface compliant to the ED-137 EUROCAE standard. All systems are also provided with 16 Controller Working Positions (CWP) to give controllers easy and intuitive access to all radio and telephone facilities needed to safely accomplish their important job for making flights safer.

The VCS delivered by SITTI is used as a backup to the three new main VCS AIRvoice full-IP ED-137 designed, manufactured and delivered by INEO E&S, a company of EQUANS France, for ASECNA ACCs together with three AIRvoice VCS systems dedicated to HF telecommunications. Such VCS redundant and fault tolerant architecture enables safe and full 7/ 24 ATM operation. INEO E&S is the main contractor of this contract and performs the programme management, commissioning, on site deployment and the logistics support, SITTI being a co-contractor.

A semi-automatic solution has been implemented to allow the local maintenance teams to easily move from the main to the backup system in a very short time. Other interesting functions included are the radio Best Signal Selection (BSS) capability and redundancy features to guarantee a continuous workflow even in case of failures, according to the fault-tolerant general principle of SITTI systems (no single point of failure).

SITTI IN THE SOUTH OF CHINA

Posted on by sittadmin

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 24th. 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.

SITE ACCEPTANCE OF SITTI SYSTEMS IN INDIA

Posted on by sittadmin

In 2019, after strong competition, AAI (Airport Authority of India) awarded SITTI a major contract for the delivery of a large number of Voice Communication (VCS) and Voice Recording Systems (VRS) to serve the whole Nation.

Following a detailed installation plan, the delivered systems have been put gradually into service, according to the identified AAI needs and requirements. SITTI is glad to be in the position of announcing that another set of systems successfully completed their SAT (Site Acceptance Test) and are ready for entering into real operation at the following cities:

  • Bhavnagar
  • Bhopal
  • Dimapur
  • Hubli
  • Trichy
  • Vadodara
  • Raipur
  • HAL Bangalore

These Voice Communication Systems belong to the top performing MULTIFONO® M800IP® family, fully compliant to the international ED 137 VoIP standard for VoIP applications in the Air Traffic Control field. They are in charge of managing local and remote radio stations, where appropriate gateway devices grant the possibility of taking full advantage of the standard ED 137 performances.

The provision of such a large number of systems and ancillary equipment to the Airport Authority of India comes after other successful projects in the same area, where SITTI products have been found as the best choice for the fulfilment of the challenging requirements set by the management of big air traffic movements. Thanks to the supplied systems and the extraordinary positive reputation gained in many years of presence in India through other large projects, SITTI is proud of supporting AAI to further contribute to the development of the Indian region.

SITTI VOIP VCSs TO DHMI, TURKEY

Posted on by sittadmin

DHMI, the Turkish State Airports Administration is currently upgrading their VCSs (Voice Communication Systems) and network infrastructure to comply with the latest air management standards, especially concerning the world famous EUROCAE ED-137 standard, which details the way VoIP – Voice over IP – has to be used in the ATC (Air Traffic Control) field.

SITTI has already been providing DHMI with TDM-based VCSs that have been installed at all main ACC centres for the management of the air traffic in the Turkish crowded skies. Such VCSs proved their robustness and reliability to a so large extent that DHMI is not going to replace them, rather to use them in parallel to the new VoIP-based systems.

The new VCSs that SITTI is installing at the main ACC and APP centres in Turkey (Ankara, Istanbul, Izmir, Antalya, Bodrum, Dalaman) will give access to a huge number of remote radio sites, in total accordance to the latest standards. Just as an example, the sole Ankara ACC will have the capability of managing more than 2400 remote VoIP radios. Similar dimensional capacities are possible at all other sites, with easily installable new interface that can be added to the system on-the-fly. The total number of new CWPs provided in this project is around 390 and the VCSs have been equipped for a total capacity of 4900 VoIP radios.

The new VCSs are accompanied by voice recording systems that complement the short-term recording feature available at each controller working position (CWP). The transition plan by DHMI foresees that controllers will be provided by a second touch screen device (CWP) for the access the new VoIP VCS features, until the time when the old one will be removed and controllers will have access to both the new VoIP and the old TDM-based VCSs from a single device.

“The modernization and upgrade of the existing VCS systems and network infrastructure” –Marco Scalia, SITTI Program Manager, says – “will allow the Turkish State Airports Administration to implement the latest top-edge technical achievements in the ATC field, to provide a more reliable and efficient service to airlines, thus making the routes between Europe and Asia even more safe.”

SITTI PRESENCE INCREASES IN CHILE

Posted on by sittadmin

After the successful commissioning of the recent system at the Carriel Sur de Talcahuano airport, SITTI has delivered another three Voice Communication Systems (VCS) to as many Chilean airports, namely Ad. La Independencia (Rancagua), Ad. Viña del Mar (Viña del Mar) and Ad. Santo Domingo (Santo Domingo), not far from the capital, in the metropolitan area of Santiago. The excellent functioning of the previous systems paved the way for the positive acceptance of the new ones by DGAC, Dirección General de Aeronáutica Civil, the ANSP of Chile.

The three new VCS systems extend the air traffic control capacity of Santiago’s main airport by interfacing with 12 analogue radios (main/standby) and another 12 VoIP radio interfaces (main/standby), plus 6 FXO and FXS lines and 6 VoIP SIP phone lines. In a more general context, the proposed architecture includes main/standby server systems and a remote client in Santiago to monitor and manage both sites remotely.

The controllers are able to access all communication resources through innovative touch screen panels known for their clearness and reliability.

The flexibility and high configurability features of SITTI MULTIFONO® M800IP® VCS systems proved to be the right answer to the requirements of the air traffic control needs here in Chile, as well as in all countries where secure and reliable radio and telephone communication means have to be provided to controllers in order to guarantee safe flights.

“The overall presence of SITTI in South America is increasing thanks to the good reputation that our systems are day-by-day acquiring on the field.” – Giovanni Modugno, SITTI Program Manager, said – “This goes together with an incredible ease of seamlessly adding new boards and controller positions without affecting ongoing activities.”
