The present invention provides retaining positions, time and a range as a history on missing of a GPS system. This work vehicle, which travels autonomously along a set travel path that has been stored in a storage device of a control device, is provided with a position calculation means that measures the position of the autonomously traveling work vehicle using a satellite positioning system, with an automatic travel means that makes the autonomously traveling work vehicle travel automatically, and with a control device, wherein the control means, when the current position cannot be measured by the satellite positioning system, stores the position and time at which the position measurement obstacle occurs and the range over which the position measurement obstacle occurs in a storage device, and displays, on a display of a display means or a remotely operated device, the fact that position measurement is impossible.
