PROBLEM TO BE SOLVED: To provide an electronic apparatus capable of more effectively reducing time required to calculate location information.SOLUTION: A satellite travel information generation 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 storage section 130. A communicating section 70 has a function receiving the radio wave signal from the navigation satellite and performs direct radio communication with another electronic apparatus located at a distance where the direct radio communication is possible. A satellite travel information reception section 22 receives satellite travel information from the another electronic apparatus via the communicating section 70. A satellite travel information update section 24 collates the satellite travel information received by the satellite travel information reception section 22 with the satellite travel information stored in the storage section 130 and updates the satellite travel information stored in the storage section 130 by using the satellite travel information received by the satellite travel information reception section 22 in accordance with collation results. A location information calculation section 124 calculates its own location information on the basis of the satellite travel information stored in the storage section 130.SELECTED DRAWING: Figure 3 |
