U1925-B High Precision 6 Axis MEMS IMU 20000g High Overload Inertial Measurement Unit

The U1925 MEMS Inertial Measurement Module is a highly reliable, high-overload-resistant, and cost-effective six-axis MEMS inertial measurement module, widely applicable in areas such as missile-borne navigation and control. The U1925 series of inertial measurement modules integrates high-performance MEMS gyroscopes and MEMS accelerometers within a single structure. The gyroscopes and accelerometers selected for the system represent the leading edge of MEMS technology for inertial devices. The three-axis MEMS gyroscopes sense the angular motion of the carrier, while the three-axis MEMS accelerometers sense the linear acceleration of the carrier. The system internally compensates for zero position, scale factor, non-orthogonal error, and acceleration-related terms across all temperature parameters, maintaining high measurement accuracy over extended periods.
