The OEM-IMU-EG320N is a commercial MEMS IMU that integrates with NovAtel's SPAN technology to deliver 3D position, velocity and attitude.



With its compact size and SPAN INS functionality, the EG320N is a powerful Inertial Measurement Unit (IMU) that offers outstanding 3D navigation and precise measurements. Its lightweight, small form factor enclosure contains accelerometers and low noise gyros.

It is extremely reliable and continuously available, even during periods when satellite signals are blocked. Furthermore, it provides rugged durability and is the perfect solution for space constrained applications that require velocity and attitude data (including pitch, roll and azimuth) as well as high performance at a low cost.
