    Overview

    1、This product is a high-performance three-dimensional motion attitude measurement system based on MEMS technology. It contains a three-axis gyroscope and a three-axis accelerometer. Through flexible selection and configuration of various types of data, different application scenarios can be met.

    2、The leading sensor fusion algorithm based on the Kalman filtering principle and with independent intellectual property rights can provide data with an update rate of up to 100Hz in real time, thereby meeting various high-precision application requirements and achieving accurate motion capture and attitude estimation.

    3、It has the country's leading high-precision turntable equipment and instruments, and the products integrate independently developed high-precision calibration and calibration algorithms to improve the measurement accuracy of the products.

    4、At the same time, we provide various host computers, operating instructions, development manuals, and development codes that users need, minimizing the development time for various needs.

    5、An attitude solver is integrated inside the module, and combined with the dynamic Kalman filter algorithm, it can accurately output the current attitude of the module in a dynamic environment. The attitude measurement accuracy is 0.2°, the stability is extremely high, and the performance is even better than some professional inclinometers.
