Product Details

90IMU is a high precision laser inertial measurement unit, which is mainly composed of housing, mounting plate, RLG, accelerometer, gyro control panel, as well as data acquisition circuit and so on. It can measure angular motion and acceleration in three orthogonal directions. The error model is embedded, which include temperature compensation model and cross-coupling model. It has the characteristics of high accuracy, good reliability, low power consumption, digital control and serial RS422 output.
