SITTI EUROCAE WG67 SECRETARY

EUROCAE is the organization that deals with the definition of operational standards relating to air traffic management and control (ATM/ATC). In particular, its working group WG67 defines how to use the VOIP technology that is at the basis of ATC modern communications. Over time, this working group has assumed enormous importance in aeronautics worldwide, because it is the place where the technology that is being used throughout the world is defined.

SITTI has been a member of this working group since its foundation. SITTI proactively contributed to the outcomes of the working group, namely the international standards known as ED136, ED137 and ED138, all dealing with Voice Over IP in the field of air traffic control. SITTI has in particular been responsible for leading the subgroup responsible for the definition of the supervision of the elements in a VOIP network based on ED137.

At the latest WG67 meeting, SITTI decided to accept the role of secretary of the working group, in the person of Mr. Roberto Weger, thus further contributing to the results that this group is expected to achieve, given the new objectives set during such meeting. The ToR (Terms of Reference) for the group, overviewing the future activities to be executed in the coming years, are still to be approved by EUROCAE; the work done till now is not finished because large areas have to be taken into consideration for integration into ED137, one of all: security.

Thanks to the exceptionally good image and competence that SITTI has been able to offer and guarantee as a primary manufacturer of reliable systems worldwide, SITTI will continue providing its effective support to the group, leveraging on the large experience and expertise accumulated in the decades-long presence in the ATC market.

SITTI IN PARAMARIBO, SURINAME

The Republic of Suriname is the smallest independent State in South America. The economic growth of the national economy and the need of enhancing the air connections infrastructure led to the search for a new Voice Communication System (VCS), capable of coping with the local needs, but already prepared for any possible future expansion. The new system is planned to be installed at the capital’s international airport, Johan Adolf Pengel International Airport.

SITTI has been chosen as the preferred supplier thanks to the high performance of its systems and the extremely good references that could be proven worldwide, and especially in South America. SITTI has therefore been awarded a contract for the provision of a new VCS system to the airport in the capital, Paramaribo close to the Atlantic Ocean coast.

The system being installed in Suriname includes a number of ED-137 VoIP interfaces capable of acting as managing both analogue and IP connections. More specifically, the MULTIFONO® M800IP® to Suriname has to deal with analogue/VoIP radio channels configured in automatic main/standby mode, plus analogue FXO/FXS telephone lines and SIP/IP telephone connections. All these communications facilities will be used by a significant number of local air traffic controllers that have access to all such features through an ergonomic and customizable touchscreen panel developed by SITTI.

The supplied systems has the native capability of being expanded seamlessly at any moment in time without affecting ongoing operations, including support for G.729 and dynamic delay compensation. FAT (Factory Acceptance Test) is expected to that place for next June, while SAT (Site Acceptance Test) by August 2020.

SITTI TO EXPAND AFIS SERVICES IN BRAZIL

The Brazilian air space is subdivided into 4 areas, each of which managed by a dedicated Air Control Center (ACC), named CINDACTA, acronym for “Centro Integrado de Defesa Aérea e Controle de Tráfego Aéreo” (Integrated Air Traffic Control and Air Defense Center). With the objective of expanding and enhancing the remote AFIS applications provided by these centers, a significant number of stations will be provided with “MultiFunctional Terminals” developed by SITTI.

MultiFunctional Terminals allow operators to have simultaneous access to integrated communications to and from SITTI VCS (Voice Communication System) and any other third-party application. External applications that can be integrated are of any kind. In the case of the Brazilian remote AFIS service, the following ones have been selected, although further future expansion is possible: Audio Center, Electronic Strips, Meteo and Cameras. The installed applications run in parallel and present their information on a single monitor, thus reducing the amount of unnecessary hardware on the operator’s desk, therefore enhancing his situational awareness and working comfort.

Multifunctional Terminals, based on the MT800 Platform developed by SITTI, will be delivered to the following stations:

  1. CINDACTA 1: Barbacena
  2. CINDACTA 2: Corumbá
  3. CINDACTA 2: Uruguaiana
  4. CINDACTA 3: Fernando de Noronha

The wide experience acquired by SITTI in the Air Traffic Control field is put at the Customer disposal not only through unparalleled Voice Communication Systems (capable of interfacing any kind of analogue/digital/VoIP radio and telephone link), but also by offering integrated solution that can greatly enhance the way tasks are carried out by controllers. The MT800 platform used for the MultiFunctional Terminals subject of this supply is another step forward in understanding and capturing customer needs and in providing modern and highly integrated solutions.

SITTI at Rancagua (Chile)

Chile is a country where SITTI is already at home. In fact, SITTI has recently supplied the Voice Communication System (VCS) to cover the needs of the national air navigation service provider, the Dirección General de Aeronáutica Civil (e.g. https://www.sitti.it/sitti-in-chile). The positive performance demonstrated by the recently supplied systems has paved the way for the expansion of SITTI’s presence in this South American country. SITTI has been awarded a new contract to supply a new VCS system at La Independencia Airport in Rancagua, located about 80 km south of the capital Santiago.

The system to be installed in Rancagua, although not a large system, includes a series of state-of-the-art interfaces with ED-137 VoIP support capable of acting as a gateway between analog and IP connections. The system will include radio channels that will increase the coverage and management of Santiago de Chile’s airspace, allowing, among other features, to manage the system remotely with security.

The system provided will be the M800IP® Multiphone since its modular and distributed architecture has the native capacity to expand seamlessly at any time over time without compromising ongoing operations. The implementation and operation of the system is part of numerous projects in South America that SITTI will complete by 2020.

SITTI is a leading manufacturer and supplier of VCS worldwide, capable of providing timely and state-of-the-art solutions to the Customer’s needs, both in the civil and military fields. The cutting-edge, redundant, non-blocking architecture of the MULTIFONO® M800IP® offers flexibility and modularity for easy expansion and the addition of more functionality.

ICEA SIMULATORS UPGRADED BY SITTI

Within the Brazilian national air force (FAB – Forza Aerea Brasileira), I C E A (Instituto de Controle do Espaço Aéreo) is the reference organization aimed at training human resources and conducting researches for the Brazilian Airspace Control System. Among the many activities carried out by ICEA, an important role is played by the provision of training to air traffic controllers that will be in charge of the correct and safe management of the steady increasing flow of aircrafts in the Brazilian skies.

ICEA is based in São José dos Campos and is already equipped with a SITTI Voice Communication System (VCS) simulator. This later is now going to be upgraded to include all training facilities to comply with the latest requirements set by the increasing usage of the IP technology in the Air Traffic Control (ATC) field. More specifically, instructors in São José dos Campos will be remotely connected to any compatible existing SITTI VCS in Brazil, therefore resulting in a much more cost effective training and reduced logistic requirements.

The upgrade process involves the VCS simulators at the LAB-SIM (Laboratorios de Simulação) and EOM (Escola de Operaçōes Militares) Audio Centers. In total, about 120 digital telephone connections will be managed by SITTI systems to allow a fruitful training at ICEA, where almost 180 controller working positions will be connected together; it is noteworthy to mention that about half of the positions are traditional ones installed into consoles, another the other half (95) is of the “stand-alone” type, i.e. they can be placed on any surface (desk).

SITTI VCS UPGRADE FOR DTCEA BRAZIL

In response to the increasing air traffic in the Brazilian skies and the related complexity of operations, the Brazilian air force (FAB – Forza Aerea Brasileira) decided to undergo a significant plan for upgrading the existing VCS (Voice Communication Systems) infrastructure already deployed nationwide. The upgrade is aiming at getting the many advantages of the VoIP architecture and protocol. The conversion to IP is the main objective that is being focused with this project. Other projects in the same direction have been completed in recent years, while the current one directly involves the DTCEA (Destacamentos de Controle do Espaço Aéreo) areas of San Paolo, Rio de Janeiro (Galeao) and Confins.

A large number of BSS (Best Signal Selection) modules are going to be installed for the management of a varying number of remote sites (from 2 to 7), to allow air traffic controllers to receive the best audio from remote radio stations nominally set to the same frequency. When considering the total amount of connections (main + emergency systems) that will be interfaced by the VCSs, one may understand the complexity and wideness of the requirements set to SITTI systems:

  • 100 Best Signal Selection (BSS) frequency groups
  • 200 Controller Working Positions (CWP)
  • 360 SIP telephone connections
  • 560 Analogue telephone lines
  • 500 Analogue-IP gateway boards

These impressive figures do not represent a problem for SITTI MULTIFONO® systems, because of their intrinsic capability of managing a very large number of concurrent communications, since they are natively ready to accommodate expansions and integrations without affecting ongoing operations. Air traffic controllers can access all communication devices (radio and telephone) that are configured on their touchscreen panels, by taking full advantage of the sophisticated algorithms implemented in the system to provide them with the easiest and most effective Human-Machine Interface for safely coping with all the tasks they are responsible for.

Once the VCS systems will have been upgraded according to the requirements set by the customer, the existing VCS systems will benefit from all the positive aspects introduced by the IP technology to better respond to the constantly changing and challenging operational needs. The wide experience of SITTI in the Air Traffic Control (ATC) field is put at disposal of the customer through top-edge systems, in compliance with international standards. The upgrade of the VCSs will be carried out in different phases, and it is expected to be completed in 2 year time.

SITTI IN THE SPACE (Episode 3)

The positive relationship with ESA (European Space Agency) and the excellent results achieved so far paved the way for the award by ESA of another contract to SITTI for the supply of 4 new ED-137 compliant VCSS (Voice Communication Switching Systems). After the delivery of the SITTI system for the Cebreros (Spain) ESA ground station the agency had the need to further equip its world wide Ground Stations network with reliable advanced mission-critical VCS systems to be connected to the main center in Darmstadt (Germany)  for activity coordination and sharing of vital real time information among spacecraft and ground network operators.

The new M800IP® MULTIFONO® Voice Communication Systems will be installed at the following four ESA Ground Stations:
·         Kiruna (Sweden)
·         Kourou (French Guyana)
·         Malargue (Argentina)
·         New Norcia (Australia)

Such new systems guarantee ESA the same top edge characteristics and performance of the ED-137 VOIP systems already supplied. All in all, the four systems encompass 58 controller working positions (CWP), 96 main/backup VOIP links, 32 E&M analogue connections, 16 digital interfaces including ISDN. The native flexibility and modularity of SITTI MULTIFONO® M800IP® systems allow to plug in a very large variety of different interfaces that convert any kind of link into standard EUROCAE ED-137 VOIP connections.
