The NF1100 MEMS Inertial North Finder adopts a strapdown north-finding solution consisting of a built-in MEMS gyroscope and MEMS accelerometer. The product can continuously track and measure changes in the inclination angle, tool face, and azimuth angle. The NF1100 Inertial North Finder integrates high-performance MEMS gyroscopes and MEMS accelerometers within an independent structure, making it suitable for high-precision attitude measurement under conditions of small pipe diameters.

The NF1000 MEMS inertial north finder is a strapdown north finding solution composed of high-performance MEMS gyroscope and MEMS accelerometer, which can directly measure wellbore inclination angle and tool face angle. The three-axis MEMS gyroscope is sensitive to the angular motion of the carrier, and the three-axis MEMS accelerometer is sensitive to the linear acceleration of the carrier. The module internally compensates for the zero position, scale factor, non-orthogonal error, and acceleration related terms of all temperature parameters, which can maintain high measurement accuracy for a long time.
