While inertial navigation is no new concept, the introduction of HRG (hemispherical resonator gyroscope) technology has surpassed previously conceived boundaries. Land, air and sea are often regarded as different universes as they relate to navigation - each with its own dynamics, environmental factors, and nuances; each affected differently by various GPS-denial tactics. The HRG technology provides industry-leading performance in a low SWaP (size, weight and power) form factor enabling new missions in GPS-denied environments.
