Key highlights

Horus is a high-accuracy single box star tracker designed with weight and cost optimization for demanding missions with a lifetime up to 18 years. Thanks to its innovative design, Horus can perform under very harsh conditions including high slew rates, temperature, protons, and straylight. Its composite baffle is a tremendous advantage providing a lightweight footprint of less than 1.6 kg per OH, up to 4 OH, and a 24° Sun Exclusion Angle.

Horus is a complementary solution in Sodern’s star tracker portfolio providing the perfect match between Hydra and Auriga™ for light, high accuracy, short lead time, and cost-effective needs. Horus’ embedded Star Catalog and Algorithms are inherited from 50 years of experience and from Hydra Star Tracker.
