DESCRIPTION The Octantis 2 series of Inertial Navigation Systems are next generation systems offering tactical performance with high-performance MEMS sensors. The Octantis 2 series is a highly integrated system with an exclusive selection of low-noise accelerometers, low-drift gyroscopes, magnetometer, barometer and multi-constellation GNSS including support for centimeter level positioning with L1/L2 RTK option. Aeron's proprietary parameter estimation engine based on multi-modal Kalman filter works optimally utilizing the high-speed processor architecture offering real-time performance in demanding applications. The system is ruggedized and qualified to MIL-810G & MIL-461F specification incorporating vibration & EMI rejecting features in design. Octantis 2 has multiple interfaces for data capture, provision for interfacing external odometer and feeding in aiding data from other systems. It also has built-in solid-state memory for data logging. The sensing elements are characterized in our in-house lab and compensated for temperature drifts, misalignment, non-linearity & other errors over the entire dynamic operating ranges. Additionally, Octantis 2 INS system has redundancy at the sensor-level. It is equipped with auxiliary accelerometers and high-rate range (2000 deg/s) gyroscopes to assist during short spells of high dynamics as well as keep system operational in the event of primary sensors failure.
Variants:
NS6300S has a single L1 GNSS receiver, suitable for standalone land and airborne applications. NS6500T has twin L1 GNSS receivers (dual antenna system) which gives better heading accuracy, redundancy in GPS and is suitable for antenna/platform stabilization and other such applications. NS7300D has dual frequency L1, L2 GPS for sub-meter positional accuracy in standalone mode. It also has centimeter level accuracy in RTK mode (base station-rover setup).
