The OEM-IMU-HG4930 is a high performing Micro Electro Mechanical Systems (MEMS) Inertial Measurement Unit (IMU). This IMU is economical, robust, small and operates on low power allowing it to provide tactical grade performance. It's ideal for use in unmanned vehicles and commercial or military guidance applications. The IMU is comprised entirely of commercial components which will simplify the export process.

NovAtel’s Synchronous Position, Attitude and Navigation (SPAN) technology can be integrated with this IMU to provide accurate 3D position, velocity and attitude data in a compact package. This combination makes the IMU ideal to use in airborne, marine and ground applications.
