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. It has undergone a range of qualification tests covering an array of use cases and associated environmental factors. Octantis 2 INS-GPS is also part of our land navigation suite offering, 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.

Product Features

Field proven MIL Qualified INS-GNSS System suitable for very demanding and harsh requirements part of various military programs.

Suitable for land navigation in GNSS compromised scenarios assuring low position drift (1% DT CEP).

10 years+ product legacy having been part of key defense programs since 2013. Supported for a long program life of 15+ years.

Accepts ground speed aiding over CAN (J1939 protocol) and over pulse odometer with configurable scale factor.
