Technical features

Product precision can be customized, wide range of applications

MF300C MEMS north finder is a highly reliable and cost-effective six-axis MEMS inertial sensor combination, which can be widely used in navigation, control and measurement fields represented by inertial navigation and attitude stabilization. MF300C MEMS north finder can be configured with different software and hardware according to the needs of users, so as to meet the needs of different users to the greatest extent.

Advanced process and technology

The MF300CMEMS north finder integrates high-performance MEMS gyroscopes and accelerometers in an independent structure. The gyroscopes and accelerometers selected for the module represent the leading level of inertial devices in MEMS technology. The angular motion of the sensitive carrier of the three-axis MEMS gyroscope, the linear acceleration of the sensitive carrier of the three-axis MEMS accelerometer,The compensation of zero position, scale factor, non-orthogonal error and terms related to acceleration for all temperature parameters is carried out in the module, which can maintain high measurement accuracy for a long time. At the same time, the module adopts measures such as overall vibration reduction and sealing design to ensure that the product can accurately measure the angular and linear motion parameters of the carrier in harsh environment.Thereby providing a low-cost and high-reliability solution for users.

High Precision Device Manufacturing and System Calibration Compensation Technology

The company has accumulated a series of key technologies in the research and development process of this project to ensure the high performance of products. At the same time, the system uses high-speed sampling, static error compensation (zero, scale factor, installation error, etc.), dynamic error compensation and other technologies to ensure the best performance of the product in the user's use process.

High quality and reliability

Through the comprehensive control of upstream and downstream processes and technologies, the company can effectively improve product quality and reduce system costs. At the same time, the company implements ISO9001 and GJB quality system, and adopts strict technology to ensure the reliability and consistency of product performance.
