OCT3-NS7700T

The Octantis 3 (OCT3-NS7700T) represents a cutting-edge, third-generation Rugged Dual Antenna GNSS-aided MEMS Inertial Navigation System. With dual antenna GNSS Compassing, it guarantees uninterrupted heading performance in static and dynamic conditions, making it the top choice for precision pointing and navigation applications.

The Octantis 3, OCT3-NS7700T, is a third generation, high-performance, Rugged Dual Antenna GNSS-aided MEMS-based Inertial Navigation Systems. The dual antenna GNSS Compassing configuration ensures uninterrupted heading performance in static and dynamic conditions. This makes OCT3-NS7700T an ideal choice for pointing and navigation applications. Engineered with Aeron’s exclusive Inertial Measurement Unit (IMU), featuring 3-axis low-noise accelerometers and low-drift gyroscopes, this system sets a new standard in tactical class performance.

 

Our in-house characterized IMU sensing elements undergo meticulous compensation for temperature drifts, mis-alignment, non-linearity, and other errors across dynamic operating ranges. The OCT3-NS7700T integrates a proprietary parameter estimation engine leveraging a multi-modal Kalman filter, powered by a high-speed processor architecture, ensuring superior performance in demanding applications.

 

The on-board Kalman Filter based sensor-fusion delivers low-drift position, velocity, and attitude estimations even in GNSS-denied conditions, operating at high update rates. Ruggedized to meet MIL-STD-704D, MIL-STD-810G, and MIL-STD-461E/F standards, the system guarantees reliability in challenging environments.

 

With versatile interfaces for data capture, external odometer/air data input, and integration with other GNSS systems, the OCT3-NS7700T offers flexibility. Its built-in low-noise magnetometer serves as a redundant heading source in GNSS-denied or poor visibility conditions.

 

The model features a multi-frequency (L1/L2/L5 (IRNSS/NavIC), multi-constellation GNSS receiver with multiple channels and unparalleled signal sensitivity. Resistant to radio frequency interference, the built-in GNSS receiver safeguards against intentional jamming and spoofing.
