Laser Inertial Measurement Unit Calibration Free|ultra-high Accuracy|super Scalability|high Stability|compact Envelope For Strap-down Positioning And Orientation Device (IMUs)




1. Brief introduction




IMU32 is a miniaturized, medium high accuracy laser inertial measurement unit. With 3 laser gyroscopes, embedded data processing system, secondary power supply module inside, the accelerometer and acquisition circuit of accelerometer, the angular/line motion of carrier’s relative inertial space can be detected.




2. Features




(1). Calibration free

The IMU level error calibration is completed, which is convenient for users' engineering application.

(2). Super scalability

The installation position of three axis accelerometer and accelerometer acquisition circuit can be reserved.

The installation position of GNSS receiver, and the antenna interface can be reserved.

Selectable secondary power supply module. (Basic + extended power)

 (3). Stable performance, strong environmental adaptability

It can be applied in environmental requirements of military grade.
