The EG320N is a Micro Electromechanical System (MEMS) IMU from Epson. It features low noise gyros and accelerometers in a small, lightweight enclosure. The EG320N enables precision measurements for applications that require low cost, high performance and rugged durability in a very small form factor. When integrated with NovAtel’s SPAN technology, this IMU is ideal for size constrained applications that require accurate 3D position, velocity and attitude data.
