NF1070 MEMS North Finder (hereinafter referred to as NF1070) is a universal, miniaturized, industrial-grade inertial measurement unit. It enhances measurement accuracy by compensating for the zero bias and scale factor of each axis based on temperature. This north finder comprises a high-precision MEMS north-finding gyroscope (with the Z-axis gyro being of high precision), a MEMS accelerometer, a high-precision motor servo system, and peripheral circuits. Under static conditions, it outputs the attitude angle in the direction indicated by the product casing.

Application Scenarios
The NF1070 is a high-performance MEMS-based north finder that integrates three-axis MEMS gyroscopes and three-axis MEMS accelerometers, delivering full-temperature compensated inertial/attitude (including north-finding) outputs via RS422 (up to 200 Hz)—well-suited for applications such as inertial navigation and attitude stabilization.
