The NF1200 MEMS North Finder is a highly reliable and cost-effective six-axis MEMS inertial sensor, widely applicable in navigation, control, and measurement fields represented by inertial navigation and attitude stabilization. The NF1200 series north finders integrate high-performance MEMS gyroscopes and MEMS accelerometers within an independent structure. The gyroscopes and accelerometers selected for the system represent the leading level of 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, while the three-axis MEMS accelerometers sense the linear acceleration of the carrier. The system internally compensates for zero position, scale factor, non-orthogonal error, and acceleration-related terms across all temperature parameters, maintaining high measurement accuracy over extended periods.
