The presence of SITTI in Brazil dates long back ago. All along the past decades, SITTI has been supporting the air traffic control centres in Brazil by providing top-edge systems, capable of managing the increasing air traffic demand and the challenging conditions of such a large geographical area.

This successful story continues today with the upgrade of the local systems used by DTCEA, ICEA and CINDACTA centres. They have been gradually upgraded to fully comply with the latest international standard, including the famous EUROCAE ED-137 standard, which SITTI has been giving active contribution to.

The latest and most advanced implementation of the provisions defined by ED137 for the use of VoIP (Voice over IP) in the Air Traffic Control field (ATC) are present in the MULTIFONO® Voice Communication System solution. Both main and standby existing systems have been gradually migrated to this new concept based system, thus giving operators access to a very large set of features and capabilities, typical of VoIP.

Existing analogue and digital connections and radio links are seamlessly connected to SITTI VCS, so that controllers can simultaneously use any kind of connection to assure a constant coverage of the Brazilian airspace and to provide safe and efficient air traffic control services to all inland and international flights.

The Brazilian air traffic management authorities are committed to give Brazil the best solutions for a safe air traffic management.” – Mr. Ornaghi, SITTI Area Manager stated – “And here is where SITTI can help with its decades-long expertise, through its leading and most effective systems, capable of being deployed in a nationwide system.


SITTI is a primary manufacturer of Voice Communication Integrated Solutions, delivering its products worldwide. In order to further better tackle the challenges in the air traffic control market, in their meeting of April 29th, the shareholders decided a re-arrangement of the roles and responsibilities in the leadership and management of SITTI:

  • Patrizia Crovato (see picture) is the new President of SITTI
  • Mario Scovenna takes on the position of General Manager
  • Andrea Sasselli assumes the role of Technical Director
  • Giorgio Donnini is in charge of the Business Development

We wish all of them a fruitful work for the present and future development of the company.


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.

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.


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.

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.


The Federal Aviation Administration (FAA) is conducting a significant Market Survey to define the acquisition strategy and validate future U.S. aviation communication systems’ requirements. As part of that campaign, the FAA has selected the best Voice Communication Switch suppliers worldwide to provide their COTS (Commercial Off-the-Shelf) systems.

SITTI is proud to be part of those.

SITTI MULTIFONO® M800IP® VCS system will be installed at the FAA William Hughes Technical Center in Atlantic City and be used by the FAA to perform market research for future voice switching procurements.

The system being provided by SITTI uses several radio and telephone connections, both analog and digital, to allow the FAA to simulate voice communications in support of execution of various operational scenarios. FAA users will be interfacing the system through 4 radio+telephone controller working positions.

This is a significant achievement for SITTI, in line with its strategy to invest strongly in the American market.  Furthermore, it is an excellent opportunity for SITTI to make the FAA and the major players in the Air Navigation field appreciate the qualities of its systems and services in terms of reliability and flexibility.

This further confirmation of our leading position in the VCS market provides us with the opportunity to broaden our supply and support to U.S. organizations and Federal Agencies that are working to replace and upgrade their current infrastructures with VoIP technology.
