IMU attitude sensor

Product Overview:

The BNS family of attitude sensors is a 6-DOF inertial measurement unit consisting of a three-axis accelerometer and a three-axis gyroscope. Through the independent calibration of each module before delivery, combined with the built-in precision compensation and noise reduction algorithm of the module, the characteristics of low zero deviation, low temperature drift, low noise, high accuracy and high sensitivity are realized.

The module has a compatible hardware design and supports two installation modes: on-board installation or independent installation. Installation surface adopts special technology to ensure smoothness.

Product Features:

1. compact structure, small volume, light weight

2. 6-axis measurement data, 3-axis accelerometer and 3-axis gyroscope

3. built-in independent temperature measuring unit

4. Industrial power supply protection design

5. support clock signal output, can cooperate with GPS or integrated into other systems

6. Support full temperature calibration and compensation

7, Angle zero bias instability index 4°/h, can effectively reduce the measurement error
