ARIETIS is an ITAR free, space qualified, rad-hard 3-axis gyroscope. Its main application is as a primary gyro (IRU) or as a coarse rate sensor in Low Earth Orbit (LEO), Medium Earth Orbit (MEO), Geostationary Orbit (GEO), telecom, earth observation and scientific missions. It uses class 1 EEE components and is developed and qualified as per European Space Agency standards (ECSS). ARIETIS has already been selected in multiple missions, notably PLATO, LSTM and ARIEL.
ARIETIS is an innovative 3-Axis Rad-Hard Gyro unit and the only gyroscope system using a European Field-Programmable Gate Array (FPGA) technology. With its High-Reliability class 1 components, ARIETIS is a high-performance, high-reliability, ITAR-free non-redundant 3-axis Gyros Unit, providing inertial angle increments measurement and rotations rates about three orthogonal axes. ARIETIS is developed and qualified as per ESA standard (ECSS) and is also designed to have a long life duration (15+ years).

In December 2016, InnaLabs® won its first contract with the European Space Agency (ESA) to develop ARIETIS, a 3-axis Rad-Hard Rate Measurement Unit for science and space exploration. However, this development also finds applications in the global commercial space market, including GEO, Telecom and Navigation platforms. In particular, ARIETIS is to be used in ESA's third medium-class mission called PLAnetary Transits and Oscillations of stars (PLATO). Its purpose is to discover and investigate a large number of extrasolar planetary systems, with emphasis on the properties of terrestrial planets in the habitable zone around solar-like stars. PLATO has also been designed to investigate seismic activity in stars, enabling the precise characterisation of the planet's host star, including its age.
Additionally, InnaLabs® is currently negotiating with a number of Space Primes for ARIETIS to be used on a variety of missions, including Science, Earth Observation, Telecom, as well as Navigation platforms. First contracts were signed in 2021, with flight models being shipped in 2023.
