Introduction
HWA-RLG5000 inertial navigation system is a standard airborne strap-down inertial navigation system that can meet the needs of large passenger aircraft and fighter jets for inertial navigation systems. It is a complete integrated navigation system, including an embedded GPS receiver, which can output the aircraft's position, speed and attitude information in real time in an airborne dynamic environment. IT can work in both pure inertial and integrated navigation modes.
