ARIETIS (REAL)-1

 

 

High-Performance Sensor System

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).

Technology Background

InnaLabs® developed ARIETIS to address coarse rate control and stabilisation in Attitude & Orbit Control Systems (AOCS) in Geostationary Orbit (GEO), Low-Earth Orbit (LEO), and Navigation in Medium-Earth Orbit (MEO). The unit is based on InnaLabs® patented CVG technology which has consistently delivered a market-leading performance to cost ratios for the past six years on land and marine stabilisation platforms.
 
InnaLabs® (CVG) technology shares common features with the Hemispherical Resonator Gyroscope (HRG) family, however, the CVG technology maintains high reliability and accuracy at a lower cost.

Space Missions

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.
