The HG1930 is a small, low-cost microelectromechanical system (MEMS) inertial measurement unit (IMU) manufactured by Honeywell. It provides tactical-grade performance for unmanned vehicles and other commercial and/or military guidance applications. When integrated with NovAtel's Synchronized Position, Attitude and Navigation (SPAN) technology, the IMU is ideal for airborne and ground applications requiring accurate 3D position, velocity and attitude data.
