MNF-N205
MEMS North Seeker
Product Overview
MNF-N205 MEMS North Seeker is a high-reliability, cost-effective six-axis MEMS inertial sensor. The module internally compensates full-temperature parameters including zero bias, scale factor, non-orthogonality error and acceleration-related terms, maintaining high measurement accuracy for a long time. Adopting integral vibration reduction and sealing design, this MEMS north finder is widely applied in navigation, control and measurement fields represented by inertial navigation and attitude stabilization.
