Whereas the world inertial navigation community was wondering, for decades, if FOG would ultimately replace RLG, Safran is demonstrating with its HRG that technology prospective is not such an easy game. With its HRG, Safran is proving that the HRG innovative approach is a real game changer in high end navigation. This paper sums up the overall principles of HRG, how it works and its intrinsic properties. Current applications of HRG are described to illustrate how HRG benefits are capitalized…
