Abstract:
A positioning apparatus having short sensory time for executing the high precision positioning of the user on a map. The positioning apparatus includes: a first positioning unit for obtaining a first position information which represents the position of the positioning apparatus itself measured by carrying out a low precision positioning; a displaying unit for displaying the first position information; and a second positioning unit for obtaining the second position information which represents the position of the positioning apparatus itself measured by carrying out a high precision positioning. The high precision positioning is executed in parallel with the low precision positioning. The displaying unit updates a screen based on the second position information.
