摘要 |
A positioning device includes a position calculation section which calculates a determined position of the positioning device based on a satellite signal S 1 and the like, a velocity calculation section which calculates moving velocity of the positioning device, a stationary state determination section which determines whether or not a stationary state condition beta is satisfied in which a time elapsed from the last positioning is within an allowable time range specified in advance, moving velocity v 0 during the last positioning is within a first velocity allowable range specified in advance, and current moving velocity v 1 is within a second velocity allowable range specified in advance, an average position calculation section which calculates an average position Q 1 by averaging a determined position P 0 during the last positioning and a current determined position P 1 , and the like.
