Abstract

PURPOSE:To prevent trouble in use by storing the map data exclusive to a user in a user memory in a relation to a map displaying the movement of a moving body on a picture and displaying the same on the picture so as to superpose the same on the corresponding existing map data. CONSTITUTION:The map data exclusive to the user of a moving body is stored in a user memory 7A and the related existing map data is stored in a map data memory device 7. Next, when the user turns the inputs start key 91 in a function key device 9 ON, the start point position of the moving body is detected and stored. When the moving body moves for a predetermined time to reach a final point, the moving route during this time and the final position are detected. When the user turns an input completion key 92 ON, the present position data is displayed along with the map of the memory 7A and the existing map of the device is displayed in a superposed state. By this method, trouble in the use of a map can be prevented.

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a navigation device for a mobile object, and particularly relates to a map displayed on a display screen in connection with the movement of the mobile object. The present invention relates to a mobile navigation device in which map data dedicated to a user of the mobile body is stored in a user memory and can be displayed superimposed on related existing map data.

[Prior Art] Radio waves are transmitted from multiple artificial satellites to various types of moving objects such as ships, aircraft, and automobiles in order to confirm or determine their current positions, moving speeds, etc. The usefulness of GPS positioning devices has been gaining attention. here,
GPS positioning device is the Global Positioning System (Globa)
It is designed to receive radio waves from a plurality of artificial satellites belonging to the I-Positioning System, and to know the current position of a mobile object.

As is conventionally known, positioning operations performed using such a GPS positioning device are usually performed by receiving radio waves from three or more artificial satellites. Then, the radio waves from the plurality of satellites are simultaneously received by the mobile object, and the difference in accuracy between the clock devices installed on the plurality of satellites and the clock device installed in the mobile object is detected. The current position of the moving object is displayed on an appropriate display means after the necessary correction processing for the time lag based on the above is performed. At this time, the necessary map information is combined with the information related to the current location and displayed on the display means.

Also, so-called self-supporting navigation devices have been known for the various types of moving objects described above. This self-contained navigation device is based on the G
Unlike PS navigation devices, it is designed to be able to determine its current location based solely on the data it acquires, without relying on external data such as radio waves from artificial satellites. be.
