Main characteristics：Main features: VG100 vertical gyroscope maintains accuracy in complex motion! VG100 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.
Product Introduction
The VG100 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 a 6-state Kalman filter with appropriate gain, which is suitable for dynamic measurement of navigation and positioning.
VG100 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 VG100 can be greatly eliminated, and the product accuracy level can be improved.
VG100 has a digital interface that can be easily integrated into users' systems.
