Navigation group member displaying method and displaying apparatus thereof

The invention provides a navigation group member displaying method. A group comprises at least two terminals in communication connection with a server, and the terminals send respective position information to the server. The method comprises the following steps: selecting at least one terminal of one registration group as a user terminal, wherein the user terminal comprises a route and a navigation map used for displaying all member information, and the terminal position information of group members sent by the server is obtained by the user terminal; calculating according to the position formation of the user terminal and other members of the group to obtain a practical distance of the user terminal to each of the other members; calculating according to the position information of the user terminal and other members in a fleet to obtain an angle between a line between the user terminal and each of the members and the Y axis of a coordinate system in the navigation map; and displaying the positions of the group members in the navigation map by utilizing a radar map according to the above practical distance and angles. The invention also provides a navigation group member displaying apparatus. The position information of other members in the group can be obtained in real time in the invention.
