Abstract
A mobile terminal according to this invention includes the first calculation module which autonomously calculates its own position based on a GPS signal, and the second calculation module which calculates its own position based on a acquired auxiliary information from a server and the GPS signal. A first control module causes a timer to start a time counting if the second position calculation module accesses the server. When the auxiliary information which satisfies a predetermined condition is not acquired in the time of the timer, the calculation module changes from the second calculation module to the first calculation module. The second control module determines the connection state with the server within the time of the timer. At the time point if the second control module determines that the connection state is an auxiliary information unobtainable state, the calculation module changes from the second calculation module to the first calculation module.
