ABSTRACT:
To provide a navigational system which allows each user to easily recognize the relative positional relationship with other navigational systems. The navigational system includes a positional information generating section for detecting current position and generating positional information. A transmitting/receiving section is provided for transmitting a first positional information and receiving positional information from other navigational systems. A storage section stores the positional information of the other navigational systems. A relative position determining section is provided for determining a relative positional relationship including a relative distance between the navigational system and the other navigational systems on the basis of the positional information of the navigational system and the other navigational systems. A display panel displays the relative positional relationship.
