PROBLEM TO BE SOLVED: To propose a method and device for continuously positioning a movable body by using wireless LAN positioning in combination with GPS positioning for performing real-time processing and continuous positioning indoors and outdoors in positioning the movable body moving indoors and outdoors by using the GPS positioning in combination with the wireless LAN positioning, and to propose a continuous positioning program for the movable body. SOLUTION: For calculating a result of uniting at a time point, only a result of the wireless LAN positioning before that, a result of the GPS positioning, and DOP obtained concomitantly to the GPS positioning, are used to make real-time processing possible. Further, a weighted average is employed using a weight with a definite theoretical basis instead of "a weighted average of the result of wireless LAN positioning and the result of GPS positioning".
