Launch

The satellite was launched by a Ariane 5 ECA rocket on 6 February 2014 during the VA217 mission. After some on-orbit tests, official satellite commissioning took place on 14 March 2014.


Payload

Although this is a common program, each country operates its own share of the payload. The satellite provides an encrypted, 3 Gbit/s throughput, using mostly Ka-band links. It carries 14 antennas including 7 mobile spot antennas, enabling positioning of steerable 1750-km diameter spot beams over operational theaters requiring a high bandwidth. France owns five beams and Italy, two. The system will enable communication with deployable ground stations (420 for France), and with drones.


Ground Segment

for the French part of the capacity is called Comcept. Comcept will provide a network of fixed and deployable ground stations using full-IP (Internet Protocol) technology. The system includes high-data-rate (HDR) ground stations which are installed in a transportable shelter and provide a speed of approximately 10 Mbit/s. The Comcept system is provided by Airbus Defence and Space and Actia Sodielec.
