With a launch mass of 6,330 kilograms, T-16 was built by Airbus Defence and Space. It will provide high-power broadcast services and great operational flexibility from five orbital slots, covering the continental United States, Alaska, Hawaii and Puerto Rico. The satellite has an expected lifetime of 15 years.
With a launch mass of 3,400 kilograms, EUTELSAT 7C is a high-power telecommunications satellite built by Maxar Technologies for markets in Africa, Europe, the Middle East and Turkey. The satellite has an expected lifetime of 15 years.
As part of efforts to develop flight experiments to measure Earth’s radiation environment, CNES has been working for close on 30 years on international cooperation agreements to carry radiation monitors on satellites. The CNES-Eutelsat cooperation agreement signed in 2016 provided the framework to fly the ICARE-NG instrument on EUTELSAT 7C. This mission, named CARMEN-4, seeks not only to measure the space environment in geostationary orbit but also and above all to characterize it throughout the orbital positioning phase using the satellite’s electric thrusters each time it crosses the radiation belts. This unprecedented experiment will improve spatial coverage of spectrometry data on proton and electron fluxes.
