mems 2 axis IMU dual-axis MEMS gyroscope assembly integrates high-performance MEMS gyroscopes in an independent
M20a dual-axis MEMS gyroscope is a dual-axis MEMS inertial sensor with high reliability and high cost performance, which can be widely used in the fields of navigation, control and measurement represented by attitude stabilization. MEMS gyroscopes with high bandwidth, low delay and low noise are used in the system, and they have good mechanical environment adaptability, which can provide guarantee for the stable control of complex products.
The M20 A dual-axis MEMS gyroscope assembly integrates high-performance MEMS gyroscopes in an independent structure, and the gyroscopes selected for the module represent the leading level of inertial devices in MEMS technology. All electronic components in the module are 100% localized. Angular motion of a sensitive carrier of a dual-axis MEMS gyroscope,The compensation of zero position, scale factor, non-orthogonal error and other parameters of all temperature parameters is carried out in the module, which can maintain a high measurement accuracy for a long time. At the same time, the module adopts structural sealing design and other measures to ensure that the product can accurately measure the angular motion parameters of the carrier in harsh environments, thus providing users with low-cost and high-reliability solutions.
