Octantis 3 INS-GNSS
Rugged Dual Antenna Inertial Navigation System for Unmanned and Land Applications
Overview
The Octantis 3, OCT3-NS7700T, is the third generation, high-performance, rugged dual antenna GNSS-aided MEMS-based inertial navigation system. The dual antenna GNSS Compassing configuration ensures accurate heading from the outset, making it an ideal choice for pointing and navigation applications such as armoured vehicles, UGVs and USVs.
Engineered with Aeron's own proven Inertial Measurement Unit — featuring 3-axis low-noise accelerometers and low-drift gyroscopes — the OCT3-NS7700T integrates our proprietary NavPro engine leveraging a multi-modal Kalman filter, powered by a high-speed processor architecture for superior performance in demanding applications.
Qualified to MIL-STD-704F, MIL-STD-1275E, MIL-STD-810H, and MIL-STD-461G standards, the system guarantees reliability in challenging environments. Its multi-frequency (L1/L2/L5, IRNSS/NavIC), multi-constellation GNSS receiver offers high signal sensitivity and is resistant to intentional jamming and spoofing.
