Document:
The LKF-MSN300 MEMS inertial North Finder employs a strapdown north-finding scheme with integrated MEMS gyroscopes and MEMS accelerometers. This system continuously tracks and measures changes in well deviation angle, tool face, and azimuth angle. With comprehensive full-temperature parameter compensation for bias, scale factor, and non-orthogonality errors across a wide temperature range, it delivers a highly reliable solution for downhole north finding and navigation applications.
