Sodern is pleased to welcome our customers at Satellite 2020 at booth #1222 in the Walter E. Washington Convention Center (801 Mount Vernon Place NW Washington, DC 20001) in Washington DC, USA from March 10 to 12, 2020!
We are looking forward to meeting you and present our product portfolio including star trackers Hydra and Auriga, and our subsets for laser-link terminals.
World leader in the development and production of star trackers, Sodern equips emblematic missions such as JC SAT 17, GEO KOMPSAT 2-B, CYGNUS NG-13 or the Airbus OneWeb constellation.
JC SAT 17 is a Japanese communication satellite designed and produced by Lockheed Martin operates in S-, C- and Ku-band.
It will carry an S-Band mobile communications payload including a flexible processor. JC SAT 17 is equipped by a Hydra star tracker with Centralized Processing (CP).
Hydra is a multiple-head star tracker with separate optical heads and electronic units, which can survive high mechanical loads and performs under very harsh conditions (such as high slew rates, protons, and stray-light).
Hydra CP hosts the software on a spacecraft's on board computer (linked to the spacecraft processor) and enables mass and cost optimization at platform level.
Launched in the same spacecraft as JC SAT 17 on February 18, Geo Kompsat 28 2B is equipped with a Hydra star tracker with 3 optical heads and 2 electronic units.
It is a South Korean geostationary meteorological satellite whose mission will be the monitoring of oceans thanks to the Airbus Space-built GOCI-II (Geostationary Ocean Color Imager-II) and the Ball Aerospace-built GEMS instruments.
Since last year, the OneWeb communication satellites launched to low earth orbit keeps expanding. On February 7th 2020, 34 Airbus OneWeb satellites were successfully launched with 68 Auriga star trackers on board (two Auriga CP in each satellite). The constellation will provide internet connection worldwide.
Auriga Centralized Processing (CP) can accommodate up to three optical heads and comes with a software library that runs on the satellite’s On Board Computer. Image pre-processing is carried out within the FPGA close-coupled with the optical head. The software library is available for different processors on demand.
Sodern provides equipment for several types of missions: Earth observation, telecommunications, resupply etc.
For instance, the Northtrop Grumman Cygnus NG-13 spacecraft docked to the ISS to resupply the three-person crew of Expedition 62 features a highly reliable SED star tracker.
SED will soon be replaced by Horus, a new star tracker in development.
It is an autonomous and robust single box standalone star tracker, using innovative technologies to associate high performance and competitivity. Horus will be available in 2021.
We are looking forward to meeting you in Satellite!
