The U4930 series MEMS inertial measurement module is a highly reliable and cost-effective six-axis MEMS inertial measurement module, which can be widely used in navigation, control, and measurement fields represented by vehicles, ships, and drones. The U4930 series inertial measurement module integrates high-performance MEMS gyroscopes and MEMS accelerometers within an independent structure. The gyroscopes and accelerometers selected for the system represent the leading level of MEMS technology inertial devices. The three-axis MEMS gyroscopes sense the angular motion of the carrier, and the three-axis MEMS accelerometers sense the linear acceleration of the carrier. The system internally performs compensation for zero bias, scale factor, non-orthogonal error, and acceleration-related terms across all temperature parameters, maintaining high measurement accuracy over a long period of time.
The U4930A series inertial measurement module can be configured with different hardware and software according to user needs.
