Brief Introduction

IMU588 Inertial Measurement Unit is a high performance tactical grade MEMS Inertial Measurement Unit, which MEMS gyroscope enjoys 1°/h (Allan) bias instability and MEMS accelerometer enjoys 30µg (Allan, ±16g range) bias instability, it adds another ± 50g (±100g optional) in Z axis, which increase the Z axis measurement range up to ± 50g (±100g), and it can output precise 3 axis outputs of angular rate and 3 axis acceleration data.

IMU588 Inertial Measurement Unit adopts latest MEMS technology and advanced MEMS components, and IMU588 has been produced in bulk, which reduces the cost deeply. IMU588 enjoys excellent measurement performance, small size, light weight, and high reliability and robustness, it can output precise measurement data in harsh environment, and it has been widely applied in rain-seeding rocket, target drone, unmanned aircraft, unmanned surface vessel, platform stabilization, etc.
