<P>PROBLEM TO BE SOLVED: To provide an electronic apparatus capable of more effectively shortening time required to calculate position information. <P>SOLUTION: A satellite travel information generating section 122 generates satellite travel information on the basis of a radio wave signal received from a navigation satellite and stores the satellite travel information in a storing section 130. A communicating section 70 has a function for receiving the radio wave signal from the navigation satellite to perform direct radio communication with another electronic apparatus located at a distance where the direct radio communication is possible. A satellite travel information receiving section 22 receives satellite travel information from the another electronic apparatus through the communicating section 70. A satellite travel information updating section 24 collates the satellite travel information received by the satellite travel information receiving section 22 with the satellite travel information stored in the storing section 130, and updates the satellite travel information stored in the storing section 130 by using the satellite travel information received by the satellite travel information receiving section 22. A position information calculating section 124 calculates its own position information on the basis of the satellite travel information stored in the storing section 130. <P>COPYRIGHT: (C)2013,JPO&INPIT |
