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 reliability and meeting performance at 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 the market in Q2 2021. Prototypes available before that date, on-demand.
