Introduction
TDH-101 MEMS Inertial Measurement unit is a highly reliable and cost-effective six-axis MEMS inertial sensor, which can be widely used in navigation, control and measurement fields represented by inertial navigation and attitude stabilization. TDH-101 MEMS inertial measurement unit integrates a 6-axis inertial sensor with a very small size. Advanced design and potting technology can ensure that the system has excellent full-temperature zero bias and scale factor performance, and has good mechanical adaptability, so that it can meet the needs of small volume and high performance in various fields.
The TDH-101 MEMS inertial Measurement unit integrates a high-performance MEMS gyroscope and MEMS accelerometer in a separate structure. The gyroscope and accelerometer selected for the module represent the leading level of MEMS inertial devices. The zero bias of all temperature parameters, scale factor, non-orthogonal error and acceleration related terms are compensated in the module, which can maintain high measurement accuracy for a long time. At the same time, the chip inside the module adopts vacuum potting, integral pot-sealing and other measures to ensure that the product can accurately measure the angular motion and linear motion parameters of the carrier in harsh environments, so as to provide users with low-cost and high-reliability solutions.
