PROBLEM TO BE SOLVED: To provide a terminal capable of grasping all positions of a plurality of terminals constituting a wireless communication network established autonomously. SOLUTION: Each of terminals 1-7 constituting a wireless communication network detects its longitude/latitude and speed and transmits its longitude/latitude and speed and the longitude/latitude and speed, received from other terminal detected them, to a terminal which requested measurement of azimuth angle through measurement of azimuth angle indicative of the direction of a terminal existing on the periphery. Each of the terminals 1-7 acquires the longitudes/latitudes and speeds of all terminals 1-7 by repeating measurement of azimuth angle, makes a map MAP1 indicating the positions and speeds of all terminals 1-7 and displays the map at a display section 22.
