The M3G-230 MEMS three-axis gyroscope assembly is a highly reliable and cost-effective 3-axis MEMS gyroscope, suitable for navigation, control, and other fields of low- and medium-orbit satellites. The M3G-230 series three-axis gyroscope assembly integrates high-performance MEMS gyroscopes within an independent structure. The gyroscopes used in the system represent the leading level of domestically produced MEMS technology inertial devices. All electronic components within the system are 100% domestically produced. The three-axis MEMS gyroscopes sense the angular motion of the carrier, and the system internally compensates for zero position, scale factor, and non-orthogonal errors across all temperature parameters, maintaining high measurement accuracy over a long period of time.
