Main characteristics：Main features: VG400 dynamic inclination sensor is a high-performance and low-cost inertial measurement device, which can measure the attitude parameters (pitch and roll), acceleration and angular velocity information of the moving carrier. The error of attitude and angular velocity is estimated by advanced Kalman filter, which is suitable for dynamic measurement of navigation and positioning.
Product Introduction
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.
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.
