Experimental Results with the KVH C-100 Fluxgate Compass in Mobile Robots

摘要

This paper presents a discussion on the use of electronic compasses in mobile robots. Different error sources are considered, and solutions are proposed to correct these errors. Experimental results show the effectiveness of some of the error reduction measures. The results also show what performance can be expected from a well-calibrated compass system. The overall most important result is that errors due to external magnetic interferences are the most severe and hard-to-correct ones.
