Main characteristics：Main features: VG500 vertical gyroscope is a high-performance, low-cost inertial measurement unit equipment, which can measure the attitude parameters (pitch and roll), acceleration and angular velocity information of the moving carrier. The attitude and angular velocity deviation are estimated by advanced Kalman filter, which is suitable for dynamic measurement of navigation and positioning.
Introduction to Inertial Measurement Unit Products
The VG500 vertical gyroscope product is a high-performance, low-cost inertial measurement unit device that can measure the attitude parameters (pitch and roll), acceleration, and angular velocity information of a moving carrier. The optimal estimation of attitude and angular velocity deviation is obtained through advanced Kalman filtering, which is suitable for dynamic measurement of navigation and positioning.
The VG500 inertial measurement unit adopts high-quality and reliable MEMS accelerometers and gyroscopes, and ensures measurement accuracy through optimal algorithms. At the same time, the sealed design and strict process ensure that the product can accurately measure the motion parameters such as acceleration, angular velocity, and attitude of the carrier even in harsh environments.
Through various compensations such as nonlinear compensation, orthogonal compensation, temperature compensation, and drift compensation, the error sources of VG500 can be greatly eliminated, and the product accuracy level can be improved.
VG500 has a digital interface that can be easily integrated into users' systems. The performance and price advantages of VG500 make it a pioneer product in replacing fiber optic gyroscopes, which can better meet various application needs.
