Document:
The LKF-MTG300A MEMS three-axis gyro assembly is a high-reliability, cost-effective 3-axis MEMS gyro assembly, applicable to navigation and control fields of low-to-medium Earth orbit satellites. Assembly integrates high-performance MEMS gyroscopes inside an independent mechanical housing. The built-in gyroscopes adopt domestically manufactured MEMS inertial sensor technology reaching advanced industry level.
The three-axis MEMS gyroscope senses the angular motion of the carrier. Full-temperature compensation for Bias, scale factor and non-orthogonality error is implemented inside the system, enabling sustained high measurement accuracy during long-term operation.
