The OEM-IMU-EG370N is a high performing Micro Electro Mechanical Systems (MEMS) Inertial Measurement Unit (IMU) from Epson. The EG370N enables higher data rate and precision measurements for applications that require high performance and rugged durability in a small, lightweight enclosure.

NovAtel® SPAN® technology can be integrated with this IMU to deliver stable and accurate 3D position, velocity and attitude. The absolute accuracy of GNSS positioning and the stability of IMU measurements combine to provide an exceptional 3D navigation and attitude solution that is stable and continuously available, even through periods when satellite signals are blocked.


  • Low noise commercial grade gyros and accelerometers
