Surface Inertial Navigation

Overview

Navigation is an accuracy business and operators often cringe awaiting the red "traffic light" warnings on their position and motion system when they pass under a bridge or by a tall structure, or when a part of their vessel blocks visibility of a key satellite. For surveyors working in a hostile area, similar losses are also likely to occur if the GNSS is being jammed or spoofed.

Our products present two major advantages:

  • our FOG-based INS/AHRS are highly sensitive to Earth Rotation and allow for a simpler North seeking solution where two GNSS-antennas are not needed anymore
  • FOG technology present the highest performances for the lowest cost of ownership, providing a much-needed peace of mind to surveyors, military or civilian.
