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

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).

Beira is the second largest city in Mozambique, on the Indian Ocean with more than half a million people. Beira hosts the largest harbour in the area, which is of great importance for Mozambique itself, but even more for other neighbour countries that do not have direct access to the sea. All these aspects make of Beira a very important city, whose airport plays a fundamental role in the economy of the whole country.

The International Airport at Beira is currently using a voice communication system (VCS) by SITTI for the control of the air traffic in the region. The VCS installed at Beira belongs to the MULTIFONO® M600S family. This latter is using the TDM technology for allowing controllers to have access to the communication facilities of the airport.

VOIP is going to be gradually introduced in the country. Because of the different technology used, VOIP radios and telephone lines cannot be directly interfaced to the Voice Communication System. To allow them to be effectively connected to the VCS, an appropriate VOIP Gateway System shall be installed, capable of converting different protocols and signals.

This is the task performed by SITTI’s Gateway Voice System (GVS) that makes it possible for the customer to continue using the current TDM system and at the same time interface and fully use new VOIP radios and telephone lines. Each card in the GVS can handle up to 8 connections to remote radios or telephones, thus giving Beira International Airport all needed communication capacity.

SITTI is a primary VCS manufacturer and supplier worldwide, capable of giving prompt and top edge solution answers 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.
