Advanced Process and Technology
OEMG300C MEMS north finder integrates high performance MEMS gyroscope and MEMS accelerometer in independent structure. The gyroscope and accelerometer selected by the module represent the leading level of MEMS process inertial device. the angular motion of the three-axis MEMS gyroscope sensitive carrier, the linear acceleration of the three-axis MEMS accelerometer sensitive carrier, the bias of the full temperature parameters, the scaling factor, the non-orthogonal error and the compensation of the acceleration-related items are carried out inside the module, and the measurement accuracy can be maintained for a long time. At the same time, the module adopts integral vibration reduction, sealing design and other measures to ensure that the product can accurately measure the angular motion and line motion parameters of the carrier in harsh environment, thus providing users with low cost and high reliability solutions.
