The HG9900 is a high performance navigation-grade Inertial Measurement Unit (IMU) designed to meet the needs of a broad range of navigation, guidance and control applications. The HG9900 has been successfully deployed on a wide range of weaponry, UAVs, stabilized platforms and commercial applications.

The HG9900’s three Ring Laser Gyroscopes (RLGs), three Quartz Accelerometers (QAs) and associated electronics are all environmentally sealed in rugged aluminum housing. In addition, it employs an internal environmental isolator system to filter unwanted sensor inputs commonly encountered in real world applications.
