Main characteristics：Main features: VG400 vertical gyroscope is a high-performance and low-cost inertial measurement device, which can measure the attitude parameters (roll and pitch), angular velocity and acceleration information of the moving carrier. Attitude and angular velocity deviation are filtered by advanced Kalman filter.
Product Introduction
The VG400 vertical gyroscope product is a high-performance, low-cost inertial measurement 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.
VG400 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 VG400 can be greatly eliminated, and the product accuracy level can be improved.
VG400 has a digital interface that can be easily integrated into users' systems. The performance and price advantages of VG400 make it a pioneer product in replacing fiber optic gyroscopes, which can better meet various application needs.
