MOBILE TERMINAL, AND METHOD FOR UPDATING POSITION DATA, AND POSITION DATA UPDATE PROGRAM OF THE MOBILE TERMINAL |
摘要 |
PROBLEM TO BE SOLVED: To prevent inconvenience due to a reduction in accuracy of current position data in a mobile terminal by preventing a reduction in accuracy due to a relative position cumulative error included in the current position data. SOLUTION: The mobile terminal includes: an absolute position detection part 1-1 detecting an absolute position of the mobile terminal; a relative position detection part 1-2 detecting a relative position of the mobile terminal; a main CPU 1-5 calculating the current position data by complimenting absolute position data with relative position data; a mobile-terminal communication module 1-7 transmitting/receiving the current position data and latest time data with updated current position data between the mobile terminals; and a current position data update means 1-6 updating the current position data of a mobile terminal to the current position data corresponding to the more up-to-date time data.
