Octantis 2 INS-GNSS

Aeron’s flagship tactical MEMS inertial navigator with integrated L1/L2/L5 GNSS supporting all constellations including NAVIC. The high performance IMU inside Octantis helps deliver best in class performance of better than 1% DT in GNSS denied conditions. Octantis INS has a 10-year-old field legacy, field proven reliability and is supported for long operational life of at least 15 years.

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 which is in service for the last 10 years and is supported for long program life. Octantis 2 INS-GNSS system delivers centimetre level RTK positioning with 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 environment 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.
