Introduction
TDMG-300C 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 stability. TDMG-300C 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. TDMG-300C has the characteristics of not being disturbed by the environment, high accuracy measurement, small volume and low power consumption, which can solve the difficulty of low accuracy of traditional geomagnetic north finding in outdoor areas such as deserts. The TDMG-300C MEMS north finder integrates high-performance MEMS gyroscopes and MEMS accelerometers in an independent structure. The gyroscopes and accelerometers selected by the module represent the leading level of MEMS inertial devices. The three-axis MEMS gyroscopes are sensitive to the angular motion of the carrier, and the three-axis MEMS accelerometers are sensitive to the linear acceleration of the carrier. The zero position, scale factor, non-orthogonal error and acceleration related terms of the full temperature parameters are compensated inside the module, which can maintain high measurement accuracy for a long time. At the same time, the module adopts the overall vibration reduction, sealing design and other measures to ensure that the product can still accurately measure the angular motion and linear motion parameters of the carrier in the harsh environment, thus providing users with a low cost and high reliability solution. The system adopts high-speed sampling, static error compensation (full temperature fine compensation of zero position, scale factor as well as installation error), dynamic error compensation and other technologies to ensure the product to obtain the best performance.
