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.

ESOC is the European Space Operations Centre for ESA, the European Space Agency. The main task of ESOC is to coordinate for ESA member States projects related to spacecraft deployment and their operations. Among these activities: coordination of launches including simulation campaigns and missions readiness, testing communication links to satellites via ESA and partners Ground Stations all over the world, satellite control and health keeping during routine operations. ESOC is articulated around Earth Observation missions, Astronomy and Fundamental Physics Missions, Solar system Exploratory Missions and many other like Navigation and Space Debris.
