PPROBLEM TO BE SOLVED: To restrain consumption of a battery of a portable terminal, without reducing THE accuracy of positional information. PSOLUTION: A device includes a data communication device 105 for collectively acquiring positional information measured at a first time interval at a second time interval longer than the first time interval; a positional information storing section 106 for storing the positional information acquired by the data communication device 105; a velocity vector generating section 107 for generating a velocity vector, by analyzing a constant period of positional information stored in the positional information storing section 106; a map storing section 108 for storing a map given the velocity vector generated by the velocity vector generating section 107; and a deduction section 109 for deducing the position for a period, until the positional information is acquired next by the data communication device 105, at a time interval that is shorter than the second time interval, on the basis of the newest positional information acquired by the data communication device 105 and the map stored in the map-storing section 108.
