1. Brief introduction
IMU32 is a miniaturized, medium high accuracy laser inertial measurement unit. With 3 laser gyroscopes, 3 quartz accelerometers, secondary power supply and acquisition circuit of accelerometer. It is a 6 axial sensor for detecting carrier’s space movement info.
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
