LKF-MSN300 High-Precision MEMS North Finder
Product Introduction

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.

Main Features
  • High performance with compact size and light weight
  • -40°C to +120°C full-temperature calibration and compensation
  • Resistance to harsh mechanical environments
  • Online upgrade functionality
  • Automatic zero-velocity heading hold
  • Configurable north-finding time
  • Installation misalignment angle correction
Applications
  • Orientation in complex environments such as mines
  • Oil well inclinometer north finding
  • Pipeline measurement
