Aldebaran FOG INS-GNSS

Superior tactical Fiber-Optic Gyro based Inertial Navigation System

Aldebaran ALD-NS3500S is a rugged, GNSS-aided, high performance Fiber Optic Gyro (FOG) based Inertial Navigation System. The device incorporates High end three axis accelerometers, three axis fiber-optic gyroscopes, and an integrated multi-constellation GNSS receiver. The sensors are characterized and calibrated in Aeron's state-of-the-art facility. Aeron's proprietary parameter estimation engine delivers fast alignment and tactical class navigation performance in a matter of minutes.

The ALD-NS3500S model has a multi-frequency (L1/L2/L5), multi-constellation GNSS receiver with multi tracked channels and best in class signal sensitivity. The ALD-NS3500S model has a multi-frequency (L1/L2/L5), multi constellation GNSS receiver, including IRNSS and best in class signal sensitivity.

The Aldebaran series INS offers superior pure-inertial performance in short-term GNSS outages. External air data/velocity and position aiding can also be provided to the system.

ALD-NS3500S is suitable for positioning and pointing in airborne, land & naval applications. Aldebaran combines top-of-the-range tactical sensors closed-loop 0.1°/hr. (BI) fiber-optic gyros and <1 mg (long-term bias) accelerometers to deliver dependable GNSS denied performance in rough, off-road, and bumpy terrain.

The gyros hold their bias under vibrations, and Aeron’s proprietary sensor fusion algorithms deliver superior navigation and position performance. Aldebaran INS has integrated L1/L2/L5 GNSS receivers supporting multiple constellations that include GPS, GALILEO, and NAVIC.
