Document:
Liocrebif LKF-MSU301 series is a high-reliability, cost-effective six-axis MEMS inertial measurement module widely used in navigation, control, and measurement for vehicles, vessels, and UAVs. It employs domestically sourced gyroscopes and accelerometers in a rugged structure suited to long-duration vibration environments such as aerial surveying. The system applies full-temperature compensation for bias, scale factor, non-orthogonality errors, and acceleration-related terms, maintaining high measurement accuracy over extended operation.
