Aeronautic gyroscope ARIETIS

for marine applications

ARIETIS is an ITAR free, space qualified, rad-hard gyro. It uses Hi-Rel class 1 components. It’s main application is either primary gyro or coarse rate sensor in LEO, MEO, GEO, telecom and exploration missions. ARIETIS is developed and qualified as per ESA standard (ECSS), meeting the most stringent quality requirements as per space industry standards.
