Abstract
A controller calculates a first bearing indicative of the bearing of a work machine based on first positional data and second positional data. The controller calculates the position of the work machine. The controller calculates a second bearing indicative of the bearing of the work machine based on a change in the position of the work machine in a predetermined zone when a determination condition, including a travel condition indicating that the work machine is traveling in a straight line, is satisfied within the predetermined zone. The controller calculates a correction value of the bearing of the work machine based on the difference between the first bearing and the second bearing in the predetermined zone. The controller corrects the first bearing based on the correction value.
