1-.A high-performance three-dimensional motion attitude measurement system based on MEMS technology, including a three-axis gyroscope, a three-axis accelerometer, and a three-axis electronic compass, providing high-precision, high-dynamic, and real-time compensated three-axis attitude angles with a wide measurement range range, excellent noise immunity, no hysteresis, and stable temperature characteristics.
2. Kalman filtering combined with a sensor fusion algorithm with independent intellectual property rights can provide data with an update rate of up to 200Hz in real time to achieve accurate motion capture and attitude estimation.
3. It has the country's leading high-precision turntable equipment and instruments, and the products integrate self-developed high-precision calibration and calibration algorithms to improve the measurement accuracy of the products.
4. Provides high-precision, high-dynamic, real-time compensated three-axis attitude angle, which can work stably for a long time in various harsh industrial environments.
5. At the same time, we provide various host computers, operating instructions, development manuals, and development codes that users need to minimize the research and development time for various needs.
6. Flexible selection and configuration of various types of data can be used to meet various application scenarios.
7. It can accurately output the current attitude of the module in a dynamic environment. The attitude measurement accuracy is statically 0.05°, the stability is extremely high, and the performance is even better than some professional inclinometers.
