Tonga Airports Ltd is the Airport and Air Navigation Service Provider for the Kingdom of Tonga, a South Pacific island nation.   Tonga is well known for both tourism and for its agricultural resources. Tonga welcomes more than 60,000 visitors annually to admire and enjoy its natural beauties. This leads to the need for a good infrastructure for air traffic control, capable of coping with the expected increase in arrivals and commercial exchanges.

Through ST Electronics (Info-Software Systems) Pte Ltd, based in Singapore, SITTI has been chosen to supply a new Voice Communication System (VCS) to the local Fua’amotu International Airport on Tongatapu Island.

SITTI proposed its MULTIFONO® M800IP® Voice Communication System, equipped with 4 (four) Controller Working Positions (CWP), plus radio, telephone and intercom facilities.

This system ensures the final customer the full compliance to the latest international ATC standards, including those related to the well known ED 137 VoIP (Voice over IP) standard, thus making the system one of the most technologically advanced solutions available on in the market. Whenever needed, the system can be seamlessly expanded by simply configuring new resources by means of its supervision and configuration software.

SITTI is a worldwide leading VCS manufacturer, capable of giving prompt and top edge solutions to Customer needs, both in the Civilian and Military fields. SITTI’s state-of-the-art redundant, non-blocking architecture of the MULTIFONO® M800IP® provides flexibility and modularity for easy expansion and addition of further functionalities.


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.
