Auriga 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 is available for different processors on demand.
The Auriga CP is flight proven as demonstrated with its continued performance on board the One Web constellation.
Auriga SA can accommodate up to three optical heads and includes one electronic unit hosting Sodern’s software and computer the attitude solution. Auriga SA features a plug-and-play solution with multiple head operation. Auriga SA achieved TRL-9 in December 2019 onboard CNES’ ANGELS satellite.
Sodern has equipped the CNES satellite ANGELS with an Auriga SA.
Hydra is a multiple-head star tracker with separate optical heads and electronic units. Enabled by its high degree of modularity, Hydra can be tailored to suit the need of every customer. Thanks to its exceptional robustness, Hydra can survive high mechanical loads and perform under very harsh conditions such as high slew rates, protons and stray-light to deliver accurate attitudes.
Hydra baseline is optimized for Earth observation, telecommunications, and science missions and can accommodate up to 4 optical heads and 2 electronic units.

Hydra M is a two heads star tracker. Hydra M has a low power consumption and a low mass.
They have trusted us:
MicroCarb, a CNES mission, is equipped with Hydra M. The spacecraft performs measurement of atmospheric spectra
Hydra CP hosts the software in spacecraft’s on board computer. The star tracker enables mass and cost optimization at platform level.
The first Earth Observation satellite KazEOsat-2 from Airbus Defence Space and its subsidiary SSTL was launched in 2014 with Hydra CP star tracker.
The launch of the meteorological satellite JPSS 2 is scheduled in 2022. Northrop Grumman innovative system will build the spacecraft for NASA, NOAA to help to study global change.
Horus will complete the Sodern Star Tracker portfolio with a new single-box star tracker, more performing with a lower weight and cost than our 15 years old SED Star Trackers.
Horus will be highly competitive and incorporate significant technological breakthroughs including its lightweight composite baffle and the revolutionary Active Pixel System (APS) detector, which uses system on a chip architecture to deliver unparalleled performance.
Horus will be available in 2021.
Data transmission via laser links offers higher throughput & security than radio-frequency. A laser link terminal is made of 4 building blocks including a laser modem, a fine pointing device, a beam expanding telescope & a coarse pointing gimbal, and connects satellites to the ground (feeder links) or to other satellites within a constellation.
The switch matrix is an innovative solution to manage photonic signals in a communication payload. The switch enables remote interconnection of a large number of fiber channels (up to 96 x 96) with very low insertion loss thereby providing a high degree of flexibility to the payload architecture.
The Approach and Rendez-vous Automated Multi-mission Integrated Sensor (ARAMIS) is a rendez-vous sensor that uses advanced algorithms for non-cooperative approach, proximity operation and docking.
JPL/NASA selected Sodern in early 2018 to supply the star tracker of the future Europa Clipper mission. Sodern thus accepted the challenge of developing a new star tracker, derived from our product Hydra, but specifically dedicated to Jupiter’s harsh environment: the most radiative in the entire solar system. The mission aims at studying Jupiter’s atmosphere and its magnetosphere; and characterizing the composition and physical properties of Europa, Ganymede and Callisto. To sustain Jupiter’s harsh environment, shielding has been added around the star tracker, radiation-resistant electrical components have been selected or developed, and a high-performance software derived from Sodern’s traditional star trackers software has been designed.
