OCTANTIS 2
Rugged High Reliability Inertial Navigation System for Land and Unmanned Applications
Overview
Aeron's Octantis 2 INS is a rugged MEMS-based navigation system that provides reliable position and navigation information in intermittent GNSS conditions. Octantis 2 is a field-proven product that has been in service for the last 10 years and is supported for long program life.
The Octantis 2 INS-GNSS system delivers centimeter-level RTK positioning with an integrated multi-constellation and multi-frequency (L1, L2, and L5) GNSS chipset. Octantis 2 NS7300D-01A is designed for land and unmanned airborne applications, and has undergone a range of qualification tests covering an array of use cases and environmental factors.
Octantis 2 INS-GPS is also part of our land navigation suite, delivering best-in-class GPS-denied performance with odometer aiding over CAN or pulse input. It features RS232, RS422, Ethernet, and CAN interfaces, all isolated for interfacing with vehicle-mounted displays, controllers, computers, and autopilot systems.
