The French Directorate General of Armaments (DGA) has contracted Airbus Defence and Space to carry out a definition study for the ground segment of the Syracuse IV satellite-based military telecommunications system.

Airbus will examine possible architectures for the Syracuse IV terrestrial network and the new capacity required by the future system.

The results will be used to ready the ground segment for the construction phase, which is expected to begin next year.

Airbus Defence and Space France Communications, Intelligence and Security (CIS) business line head Eric Souleres said: “Airbus is fostering its role as a partner of choice in the field of satellite-based military telecommunications in France.

“Our French teams will be pooling their expertise in the fields of networks, telecommunication satellites, military transmissions and cyber security.”

The study involves examining the pervasiveness of Internet Protocol technology and the exponential increase in the transmission speed requirements of the Armed Forces while maintaining security and a very high level of availability.

"The study will help define the safeguards and resilience mechanisms that are required to tackle cyber threats effectively."

Airbus will use advanced network management technologies to perform network sizing, flow management and prioritisation.

The company will also investigate the capacity optimisation of the future Syracuse IV satellites by using the latest generation of modems.

The study will help define the safeguards and resilience mechanisms that are required to tackle cyber threats effectively.

It also covers optimisation of through-life support and integrated logistical support for the Syracuse IV system.

The Syracuse IV satellite communication programme not only includes construction of the user ground segment but also covers construction of two satellites, which will replace the Syracuse 3A and Syracuse 3B satellites that are currently in orbit.
