Ejercito Del Aire, the Spanish Air Force, have been looking (through ATOS company) for a military conformant Voice Communication System (VCS) to be installed at the Villanubla Tower. MULTIFONO® M800IP® by SITTI natively has all required characteristics that best suit the end customer needs. SITTI has therefore been awarded a contract for the supply of a military-shaped VCS system to be installed in the second half of the current year.

Ejercito Del Aire asked for some new features that are deemed to be very useful in their environment. The relevant adaptation has been agreed and implemented in a seamless way, thanks to the flexible and extremely modular manner both hardware and software parts are designed. Furthermore, the supplied system shall be capable of seamlessly be expanded by at least 50% of its initial capacity. Here again the SITTI approach to modular architecture plays a fundamental role, thus allowing expansion in an extremely smooth way.


SITTI is a world primary system supplier and integrator of Operational and Technical solutions for Air Traffic Control for both Civil organisations and Military Air Forces. SITTI is not only known for high technology and reliability of their Voice Communication Systems, but also for the relevant ancillary equipment and Controller Working Position consoles for use in airfield towers and Air Traffic Control Radar and Procedural Centres.

ATC Controllers are tasked with a heavy and responsible workload. As such, they deserve an ergonomic and easy-to-use environment to access all required communication and control facilities (e.g. Radar and Radios). In line with these requirements, SITTI Workstation Consoles are designed with high consideration for Operator comfort and fatigue related factors, whilst providing efficient and effective access to equipment and services for long term daily use.

Croatia Control, the state-owned company operating in the Republic of Croatia to provide air navigation services (ANS), finalised an order to SITTI for the supply of a number of consoles to be installed at the approach centres (TMA) and airfield towers (TWR) of Zagreb, Pula, Zadar, Split, Dubrovnik. Following strict regulations and special requirements from the customer, SITTI customised its consoles to fulfil the customer needs.

The end user is at the core of SITTI interest when it comes to consoles. Design criteria also took into consideration such aspects as choice of materials, seating adjustment, optimisation of viewing angles and conditions, noise isolation and ventilation, touch and feel aspects, as well as the correct positioning of communication elements (keyboards, connector panels, loudspeaker location etc.).

FAA VOIP Interoperability

During the first two weeks of May, the Federal Aviation Administration (FAA) in the USA has been hosting a very important event, aimed at the verification of the true interoperability between equipment from different vendors. The goal is to check whether VCS systems, radio devices and recorders can work together using the brand new ED137C standard, i.e. the C version of the world famous ED137 standard on VOIP in the ATM field.

14 vendors gathered in Atlantic City to run a large number of tests, thus proving the completeness and robustness of the standard on one hand and of their equipment on the other hand. Pairings between all vendor equipment have been executed, in order to allow e.g. SITTI VCS system to be interfaced to any other VCS, Radio, Recorder from different manufacturers.

SITTI has been participating in the event with a full ED137C standard compliant system, composed by Controller Working Positions and radio/telephone VOIP interfaces. The result of the tests has been beyond expectations, thus not only confirming the compliance of SITTI systems to the latest available standards, but also consolidating the modular and scalable software and hardware architecture of the MULTIFONO(r) M800IP(r) VCS system.

MULTIFONO(r) M800IP(r) is the top-edge VOIP ED137 VCS system developed by SITTI, worldwide.


As part of its expansion program, SITTI is looking for talented graduates and/or students to be integrated in its workforce. Both recruitment and internship opportunities are available.

Continuing the positive relationship with the Engineering University in Milano (Politecnico), SITTI will be participating in the CAREER DAY initiative, promoted by the Career Service, and aimed at allowing graduates and students to meet the industry. SITTI is willing to cover 5 open positions, namely:

The World ATM Congress (WATC) in Madrid is the place where the ATM and ATC players and stakeholders meet once a year to show their achievements. WATC is in fact the world most important event for Air Traffic Management, organised by CANSO (Civil Air Navigation Services Organisation) and ATCA (Air Traffic Control Association). The show in Madrid is the right place where to deliver innovative products and meet customers, having a look at the future market trends.

Continuing the positive and uninterrupted tradition since many years, SITTI has been participating in the World ATM Congress in Madrid from March 12 to March 14, 2019.

As a market leader in Voice Communication Systems worldwide, SITTI showed visitors from many ANSPs its top-edge systems and integrated functions, including recording systems, handy integration of air management applications, Controller Working Positions (CWP) with unparalled configurable features. The list of products offered to customers has increased, not only enlarging the offer of even more performing radio and telephone interfaces, but proposing SITTI as a one-stop supplier, capable of delivering complete turn-key solutions, based on ED137 VOIP technology, not forgetting the interface and integration of analogue and digital legacy communications.

The excellent opportunities offered by this exposition, allowed SITTI to confirm its reputation as a reference point in this market. A product catalogue can be download at the following links:


SITTI is proud to announce to have signed a contract with ORO NAVIGACIJA (the State Lithuanian Air Navigation Service Provider) for the installation of a new Voice Communication System (VCS) at their Area Control Centre (ACC) premises in Vilnius. This new contract reinforces SITTI presence in the Baltic region, on both the Civil and Military markets, with its top-edge MULTIFONO® M800IP® system.

The supplied M800IP® VCS systems comes along with more than 50 Controller Working Positions (CWP), which are part of the supply, in order to fulfil different customer needs: console-integrated positions and a desktop version, which can be used at an ordinary work place. The high level of function integration at all CWPs allows controllers to easily and intuitively interface the Radio communication facilities provided by the M800IP® system, as well as Telephone and Intercom management, including ATS/QSIG.

A Duplicated GPS Master Clock System is also part of the order. Factory Acceptance Tests are envisaged for next March, while Site Acceptance Tests are planned for May 2019.

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.


At the beginning of 2018, the Italian Ministry of the Interior commissioned SITTI the upgrade of the Fire Brigades operational rooms covering the entire peninsula. The contract was assigned to SITTI in the frame of the modernization of the Fire Brigades communication facilities, under the supervision of the General Direction in Rome, Dipartimento dei Vigili del Fuoco, as part of the European Unique Emergency Number 112 (NUE).

The upgrade activity involved 46 provincial commands of the Fire Brigades, for a total of 152 Controller Working Positions. In total 78 commands are being using the provided upgrades, for a total of 290 positions. This required a large need for coordination of the interventions, in order not to disrupt nor hinder the operational tasks assigned to the operational rooms, so that the level of assistance to the population is unaffected. The seamless transition to the new features assured continued presence of qualified personnel for dealing with emergency situations.

The positive result of this wide upgrade program once more confirmed the flexibility of SITTI products, that can be used for air traffic control as well as in the public assistance and civil defense fields.


Following the positive experience with the Voice Communication System (VCS) from SITTI, the Georgian Air Navigation Service Provider SAKAERONAVIGATSIA decided to upgrade the MULTIFONO® M800IP® VCS systems deployed in the country to support simulation, frequency monitoring, local analogue radios. The affected sites are the major Georgian cities: Tbilisi, Kutaisi, Batumi.

The upgrade of the existing Voice Communication System in Tbilisi will allow simulation exercises in the dedicated simulation room close to the Tbilisi ACC Centre: tower controllers and pilots simulate their activities for training purposes in all weather and traffic conditions. This is accomplished through the flexible way the MULTIFONO® M800IP® is designed, thus allowing any new addition of positions and simulated radio/telephone lines. The frequency monitoring facility being implemented at the Georgian air traffic control centers gives controllers and technicians a clear view on how radio resources are being used in real time.

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.


ESOC is the European Space Operations Centre for ESA, the European Space Agency. The main task of ESOC is to coordinate all operations for European projects concerning space and satellites. Among these, coordination of the launch simulation and testing facilities, connection to satellites and communication ground stations all over the world, satellite control and maintenance activities, space observation, research studies, and many other related projects. Collection, analysis and distribution of geo-climatic, geographical and hydrological data is also among the tasks carried out by ESA/ESOC. Here is a link for further information about ESOC operations: www.esa.int/ops

ESOC had the need to migrate its connections to the outer world from their legacy analogue interfaces to modern, high-performance and robust VOIP interfaces, to be able to reliably connect to remote ground stations, other space agencies and space centres (e.g. NASA) for the coordination for all variegated, vast and complex ESOC projects. After comparing systems from different vendors, ESOC chose the solution proposed by SITTI as the most suitable for their needs.

SITTI has been providing ESOC with a large M800IP® MULTIFONO® Voice Communication System (VCS) made of 133 operative positions distributed in several buildings. Such positions allow ESOC staff to be connected to their partners worldwide through about 30 telephone gateways for IP PABX lines and further about 60 VOIP connections to ground stations, thus making communications mainly based on VOIP. The delivered VCS architecture is duplicated in all system components, making up an operative and an emergency system for possible contingency events. As a remarkable note, the installation of the new SITTI system did not require changes to the existing network infrastructure, thus reducing the migration costs for ESOC.

SITTI is very proud of contributing to the empowerment of ESOC, by supplying the switching and interface components needed for efficient communication. The use of M800IP® MULTIFONO® in a so challenging environment like a space agency furthermore confirms the flexibility and robustness of SITTI products.
