NF1000 Strapdown MEMS North Seeking Gyrocompass / Azimuth Finder IMU, 200Hz RS422
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.
