InnaLabs® Awarded Space Contracts by Space Primes
InnaLabs® has been awarded the contract for the European Space Agency (ESA) Copernicus LSTM Science...
POLARIS is an ITAR-free, Single Event Latch-up tolerant and high-performance Inertial Measurement Unit (IMU). It provides to user equipment on a digital RS422 interface, velocity increments and angle increments about three orthogonal measurement axes. Developed with the support of the European Space Agency (ESA), POLARIS is designed for short to medium-term space missions, including launchers, micro-launchers, landers and re-entry vehicles for which the driving issue is robustness to SEE, reliability and meeting performance at a reduced cost and size.
Additional product specifications, outline drawings and block diagrams, and test data are available on request.
The core Gyro technology used in POLARIS is InnaLabs® patented and proven solid-state CVG technology (Coriolis Vibratory Gyroscope). InnaLabs® CVGs are inherently stable, impervious to aging effects in space missions, low mass, low power consumption and achieve outstanding Angular Random Walk.
The CVG perfectly balances with InnaLabs® miniature fused Quartz pendulous accelerometers. These accelerometers are derived from InnaLabs® AI-Q-550, which is an aerospace-grade design delivering dub-milli-g long term stability in high-dynamic environments.
POLARIS will be released to market in Q4 2021. Prototypes available in Q2 2021 (on demand).
