Introduction
TDMG-201H MEMS Inertial Measurement unit is a highly reliable and cost-effective six-axis MEMS inertial attitude system, which can be widely used in navigation, control and measurement fields represented by vehicles, ships and UAVS. The TDMG-201H series inertial measurement unit integrates high-performance MEMS gyroscopes and MEMS accelerometers in a separate structure, and the gyroscopes and accelerometers selected for the system represent the leading level of MEMS process inertial devices. The three-axis MEMS gyroscope is sensitive to the angular motion of the carrier, and the three-axis MEMS accelerometer is sensitive to the linear acceleration of the carrier. The zero position of all temperature parameters, scale factor, non-orthogonal error and acceleration related terms are compensated within the system, which can maintain a high measurement accuracy for a long time.

The three-axis MEMS gyroscope is sensitive to the angular motion of the carrier, and the three-axis MEMS accelerometer is sensitive to the linear acceleration of the carrier. The zero position of all temperature parameters, scale factor, non-orthogonal error and acceleration related terms are compensated within the unit, which can maintain a high measurement accuracy for a long time. At the same time, the unit adopts sealing design and other measures to ensure that the product can accurately measure the angular motion and linear motion parameters of the carrier in harsh environments, thus providing users with low-cost and high-reliability solutions.
