SITTI MULTIFONO TO SAUDI AIR FORCE

The positive relationships with our final customers allowed SITTI to be awarded through LEONARDO – a global high-technology company, among the top world players in Aerospace, Defense and Security and Italy’s main industrial company – the supply of a new MULTIFONO® M800IP Voice Communication Switching System (VCS) for a military base in Saudi Arabia, utilized for the control of routine military flights. The system to be delivered extends the presence of SITTI in the Middle East, thus confirming its capability of adapting its products to the different needs of customers.

The new VCS system has the capability of interfacing 20 VHF/UHF analogue radio channels and as many analogue telephone links making up the existing communication infrastructure, but complemented with SIP telephone links in compliance with the latest available VoIP standards.

Operators utilizing this system will have the possibility of accessing all lines and channels in the easiest possible manner, so to provide an excellent military Air Traffic Control service. Their touchscreen panels are freely configurable by means of the supervision and management software that is also part of the supply.

Time synchronization is of great importance in this kind of installations; this is why a GPS master clock module is also included, together with slave display units.

Factory Acceptance Tests are foreseen for mid July 2021, while the transition to the real operational state is planned for October 2021. All involved personnel will also undergo an on-site training phase for allowing complete autonomous management of the system.

Military and civil SITTI systems are based on the same extremely valuable and reliable architecture that proved its capability of coping with differentiated environments.

OCEANIC HF COVERAGE THROUGH SITTI VCS

The Brazilian ANSP, CISCEA, launched a project for renewing the HF radio coverage over the Atlantic ocean by replacing obsolete radio devices installed in Recife, Belem and Rio de Janeiro and connecting the new ones to the Atlantic ACC VCS system. The radios will be initially connected to the CINDACTA3 technical room (in Recife) via TDM network. The project includes the possibility to be updated to operate through MPLS network.

The Recife VCS is in charge to grant automatic receiver and transmitter radio pairing, frequency tuning, squelch selection, SELCALL, ALE, etc. managing multi-site HF remote radio stations, each one configured with multiple transmitter and receiver equipment. The project includes the possibility of expanding the implemented architecture to allow interoperability with the military HF radio network.

The MULTIFONO® VCS systems by SITTI are natively capable of coping with the multi-site configuration required by this project, allowing radios at different sites to be connected to the VCS with complete control over communications, and by providing appropriate usage functions to operators. HF Multisite operation cannot use the VHF offset facilities. For this reason, and due to the HF audio signal characteristic, HF Best Signal Selection (BSS) requires advanced audio analysis algorithm to operate.

The wide experience acquired by SITTI in the Air Traffic Control field is once again put at the Customer disposal by exploiting SITTI integrated solutions to fulfil the needs of HF coverage over the ocean, thus contributing to the safety of all flights to and from Southern America.

SITTI GATEWAYS ALLOW FILES AND DATA ON HF

The Brazilian Air Force is aiming at allowing the transmission of files and data over their existing HF radio network, not just limited to voice. This project, where SITTI is playing a key role, integrates itself with another project that is targeting the enhancement of the HF coverage of the oceanic region under Brazilian responsibility.

SITTI is providing gateway functions between external systems generating or requesting data files and the HF radios. This allows external third-party applications to access the military HF network and to send/receive data over it. SITTI is in charge of interfacing such applications and provide them with proper access to the network, according to customer requirements, over the INTRAER or ATN-BR networks.

Local and remote operators will be permitted to select the set of radios that best suit their mission and to dynamically associate such radios to external applications for data transmission/reception to/from aircrafts. This contributes to the optimisation of the usage of the entire system and network and improves their overall performance. Voice communications are of course always possible.

This project integrates the standard Radio Automatic Link Establishment features (ALE2G) to the data transmission, both in reception and transmission mode. When an incoming call is recognized the call is automatically answered and the best communication channel is automatically tuned to grant the best data transmission rate.

This project underlines the flexibility of SITTI systems. These in fact can provide features beyond just switching voice communication patterns, but also allowing the seamless integration of the management of new features, without compromising any of the other functions available to controllers.

NEW FIREFIGHTERS OPERATIVE ROOM AT BRESCIA

Firefighters are an extremely important resource for a country. They provide an unparalleled support to local communities in many fields, not just related to fire, but whenever lives are in danger because of floods, earthquakes, incidents, fires, smoke, and many other possibly dramatic events and/or in presence of dangerous substances. They therefore deserve our admiration and thankfulness. Their competence and strong capability of facing such difficult scenarios is based on their excellent training and coordination. This latter requires the use of advanced technological communication systems and solutions, capable of giving central operative rooms the means for timely alerting the personnel for a quick intervention and for coordinating their work.

Following the European directives on the Standard Emergency Number 112, the operative room in the city of Brescia (Northern Italy) has been upgraded with 6 new operative positions with radio and telephone communication capabilities. These constitute the core of the coordination capacity of firefighters in their area of competence. SITTI contributed to the success of the upgrade through the supply of the working positions connected to a new Voice Communication System (VCS) belonging to the MULTIFONO® M800IP® family.

Before the installation of the new positions, the operative room already had another 6 positions with similar functionalities. These latter have been moved to form a completely separated emergency room. The two rooms are both operational, one being the backup of the other one. They can however work together as a joint operative room in case of heavy emergencies or natural disasters; in this case 12 positions can be used at the same time to give the population the best service possible.

SITTI is very proud to have contributed to the upgrade of these operative rooms, which will be followed by similar activities at all other Italian firefighters operative rooms, so that all brigades will be equipped with their main and backup operative rooms. The M800IP® VCS by SITTI once again proved its flexibility and capability of being implemented in different fields, by giving users the best tools for integrated radio and telephone links, wherever secure, configurable and controlled communications are required.

SUCCESSFUL VCS SWITCH-OVER AT EDINBURGH

Edinburgh, Scotland, April 2021 – An important result has been achieved in recent days at Edinburgh AirportAir Navigation Solutions (ANSL), the resident Air Navigation Service Provider (ANSP), successfully completed the transition to the new Voice Communication System (VCS) provided by SITTI. The old system, which has been serving the Scottish capital for many years, has been definitively switched off in favour of a new modern Voice over IP (VoIP) system.

SITTI, world leading supplier of VCS systems, has been awarded the supply of a full standard compliant new voice switching solution that represents a big step forward for the modernization of the local Air Traffic Control (ATC) infrastructure. This big success is the result of three concurrent and integrated aspects, which greatly contributed to the final result:

  1. the VCS itself, the best solution on the market for the management of airport ATC
  2. the high level of professionalism of ANSL staff
  3. collaboration between ANSL and SITTI personnel which enabled the switch over to take place in spite of challenges created by Covid-19

A similar project is underway at Gatwick, the London airport managed by ANSL, where another similar VCS is completing its fine tuning to shortly become fully operational.

Both systems belong to the MULTIFONO® M800IP® family developed by SITTI in full accordance with the latest standards in the air management and air traffic control fields issued by EUROCONTROL and EUROCAE, with special focus on the ED-137 VoIP standard, which M800IP® is fully compliant to. M800IP® systems have undergone countless interoperability tests and operational assessments around the globe, offering advanced interfacing capabilities, reliability and flexibility. These VCS systems are equipped with interface units for connecting both digital and analogue radios and telephones and converting them to standard ED-137 VoIP links.

The VCS replacement at Edinburgh and Gatwick is driven by ANSL’s commitment to providing a very high level of service to airports and airlines through innovation and future proof solutions for integrated and efficient air traffic management processes. The productive collaboration between ANSL and SITTI made it possible to tackle the sometimes complex operational aspects and situations in the Air Traffic Control field, where the main focus is to ensure and increase flight safety.

CONCEPCION (CHILE) – SITTI SYSTEM

Continuing its expansion and progress in their modernization project, DGAC has installed a new VCS (Voice Communication System) at Concepcion. DGAC (Direccion General de Aeronautica Civil) is the Chilean ANSP (Air Navigation Service Provider) which SITTI has established an excellent relationship with, that allowed several other airport facilities to be equipped or upgraded with SITTI systems. These latter proved their reliability and capability of coping with local needs and requirements, as testified by the numerous installations in the country.

The international airport Carriel Sur of Concepcion is one of the largest airports in Chile, serving domestic and international flights, and also acting as an alternate airport for the main airport in the capital, Santiago del Chile. The number of connections to be managed at this airport is very significant and deserve a proper management to allow air traffic operators to have full access to all communication resources at any time.

The MULTIFONO® M800IP® solution offered by SITTI bases itself on our well proven architecture that makes it possible to avoid any single point of failure, thus guaranteeing an extremely high reliability and availability ratio.” – Pietro Lucioli, SITTI Program Manager, explains – “All active elements are connected to the duplicated high speed backbone LAN, in charge of distributing all messages and information to the system components.

Both E&M analogue and ED137 VoIP radios are connected to the VCS in main/standby mode, also providing Best Signal Selection (BSS) functions for the choice of the best received radio signal. At the same time, controllers can access more than 100 telephone lines (both analogue and SIP/IP). 8 brand new controller working positions (CWP) are envisaged; they are physically remote from the central unit, connected via duplicated optic fibre. GPS digital clocks and display units complete the system.

The new VCS has gone operative in March 2021, after deep testing and proper training of the controllers.

SITTI IN AZERBAIJAN

SITTI will be providing a brand new VCS (Voice Communication System Solution) for Azerbaijan airports. This is not the first time SITTI is supplying its systems and solutions to this country. In 2019, in fact, SITTI VCCS was chosen  for  the Airspace Supervision & Efficiency Center (ASEC) in Baku, which is part of Azeraeronavigatsiya (AZANS), the Azerbaijan Air Navigation Service Provider, to optimize the airspace utilization in the region.

The new  system belongs to the topmost category of VCS systems developed by SITTI. It is a MULTIFONO® M800IP® Voice Communication System, fully compatible with the most recent communication standards issued by international standardization bodies like EUROCAE and EUROCONTROL.
