Octantis Inertial Navigation System

Ideal for Precise position, attitude and orientation information.

Octantis 2

Octantis 2 is a more refined INS-GPS from the Octantis family. In addition to all the features that Octantis 1 has, it makes use of vibration suppressing high quality (1 deg/hr.) gyros. This system is compact  and space efficient compared to Octantis 1.

Octantis 1 (Obsolete)

Octantis inertial navigation systems are tactical grade GNSS aided MEMS based Inertial Navigation Systems (INS-GPS), for precise position, attitude and orientation information. Octantis is a MIL spec NAV system integrated with multi-constellation GNSS. The system runs a multi-mode Kalman filter making it suitable for high and low dynamic applications.
