High performance embedded GNSS INS (EGI) based on FOG sensors technology for safety critical airborne applications

Abstract

Fiber Optic Gyroscope (FOG) is a truly and unique solid state technology that allows compact, lightweight and accurate sensors technology to provide orientation and position with or without GNSS availability. The INS (Inertial Navigation Systems) realized is an autonomous system that can operates in absence of GNSS and is essential for airborne application where safety is involved (i.e. the system provide heading, attitude and position autonomously in case of GNSS lost). We have developed what we believe is the first ITAR free INS based on FOG technology certified (DO-178, DO-160, DO-254) for high performance airborne applications. We will present system specifications and flight test results.
