Abstract
An electronic control device capable of suppressing variations in the position of a work machine calculated based on satellite signals received by a GNSS terminal due to changes in the GNSS communication environment, and eliminating the position error after improvement of the communication environment in a shorter time than before. The electronic control device determines whether the positioning quality is good or poor based on GNSS; information, determines the traveling state, including a stop state, based on the velocity of the work machine, and performs smoothing processing to the GNSS information. The processing intensity is changed to weak if the smoothing condition is not satisfied, the condition being that the positioning quality is good and the traveling state is stop, and the processing intensity is changed to strong after a time equivalent to update cycle since the smoothing condition has been satisfied.
