Auriga™
The compact star tracker for small satellites constellations
Auriga™ star tracker is is packed with the latest high-tech components and is optimized for the small satellite markets of less than 500kg and for New Space projects as of 6U.
Radiation-resistant with a thicker casing and spacial optics, Auriga™ allow a lifetime of over 15 years in geostationary orbit and 10 years in low Earth orbit (LEO 400-1,200km). With its standardized components, is
specifically designed to meet cost reduction objectives while offering excellent technical performance and reliability. Its reduced volume (66 x 59 x 94 mm) and its weight of 225g make it the most compact star tracker in its category.
Over 1,000 Auriga™ are in orbit with a mission success rate of 100%.

- Auriga CP is composed of an optical head which integrates image pre-processing
- The software provided by Sodern is implemented in the satellite’s on-board computer and enables three optical heads to be processed at the same time

- The star tracker software is implemented in a specific electronic unit, supplied by Sodern
Horus
Single box star tracker
Horus is an autonomous star tracker which uses innovative technologies to guarantee performance and competitiveness for applications which require a single field of view. A robust and very recent product, Horus is particularly adapted to telecoms platforms.

- New generation APS space detector (Active Pixel Sensor)
- Processor integrated into a single component
- Light composite baffle
Hydra
Highly resilient modular star tracker
Hydra is a star tracker which provides modularity and performance thanks to a range of versions. Providing exceptional quality and resilience, Hydra is installed in particular on board the main institutional and scientific missions of several countries, as well as on telecommunications and observation satellites in all orbits.

- Best-in-class performance as part of Hydra product line
- Standardized Hydra definition, shortened lead-time and optimized cost
- Centralized Processing (CP) version enabling extra mass & cost optimization at system level
- Versatile, robust & accurate – Flight proven since 2014 with several hundreds units currently in-orbit

- Hydra CP is composed of an optical head which integrates image pre-processing
- The software provided by Sodern is implemented in the satellite’s on-board computer and enables one optical head to be processed

- Hydra M is a low consumption/weight version
- Thanks to advanced software processing, it enables normal performances to be maintained without requiring active thermal regulation in the optical head
- Therefore, the unit is lighter and the head’s consumption is less than 1W

- Hydra TC is a version with 2 separate optical heads and 1 electronic unit with redundant electronics
- Hydra TC is the best compromise for Geostationary satellite applications which require performance and availability

- Configuration with up to 4 optical heads and 2 electronic units
- Recommended for missions which require high performance and reliability through multi-head management
