Overview
1. This product is a high-performance three-dimensional motion attitude measurement system based on MEMS technology.
It contains three-axis gyroscope, three-axis accelerometer, three-axis electronic compass, GPS+BD module and other motion sensors.
By integrating various high-performance sensors and using the independently developed attitude dynamics core algorithm engine,
combined with the high-dynamic Kalman filter fusion algorithm, we can provide customers with high-precision, high-dynamic,
real-time compensated three-axis attitude angles. Flexible selection of configurations to meet different application scenarios.
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 200Hz 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 self-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 to minimize the research and development time for various needs.
