Navigation system
First Claim
1. A navigational system for detecting a current position to generate positional information, comprising:
- transmitting means for transmitting positional information of said navigational system;
receiving means for receiving positional information of other navigational systems;
relative position determining means for determining a relative positional relationship including a relative distance between said navigational system and said other navigational systems on the basis of the positional information of said navigational system and said other navigational systems; and
display means for displaying said relative positional relationship, and said display means also displaying identification information corresponding to said other navigational systems when a distance between said navigational system and said other navigational systems has exceeded a predetermined limit distance set by an operator.

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.
