Precise Shearer Positioning Technology Using Shearer Motion Constraint and Magnetometer Aided SINS [PDF]

open access: yesMathematical Problems in Engineering, 2021
The key technology to realize intelligent unmanned coal mining is the strapdown inertial navigation system (SINS); however, the gradual increase of cumulative error during the working process needs to be solved. On the basis of an SINS/odometer (OD)-integrated navigation system, this paper adds magnetometer (MAG)-aided positioning and proposes an SINS ...
