The OEM-IMU-HG4930 MEMS IMU provides accurate 3D attitude, velocity and position data in a compact package, making it ideal for ground, marine and airborne applications.



The OEM-IMU-HG4930 Inertial Measurement Unit (IMU) from NovAtel is a high performing Micro Electro Mechanical System (MEMS). The unit is small, robust and economical, and uses low power. This allows it to deliver tactical grade performance and makes it ideal for commercial or military guidance applications and unmanned vehicles. The IMU is manufactured from commercial components, which simplifies the export process.

NovAtel’s Synchronous Position, Attitude and Navigation (SPAN) technology can be integrated with this IMU, thereby providing accurate 3D attitude, velocity and position data in a small package.

SPAN technology combines two different but complementary technologies: Inertial Navigation Systems (INS) and Global Navigation Satellite System (GNSS) positioning. The highly accurate GNSS positioning and the stable Inertial Measurement Unit (IMU) gyro and accelerometer measurements combine to provide an exceptional, stable 3D navigation solution that is continuously available, even at times when satellite signals are not available.


  • 100 Hz data rate
  • 5 VDC power input
  • MEMS gyros and accelerometers
  • SPAN GNSS+INS functionality
  • Ideal for size and weight constrained applications
