BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The present invention is composed of a computer section A, a GPS receiving section B and a wireless transmitting section C. In the computer section A, a central processing unit (CPU) 1 is built in a small portable computer body 10.
The central processing unit 1 operates according to a program stored in the memory 2 (RAM). Further, the computer main body 10 is provided with an IC memory card slot, and the IC memory card slot stores an electronic map database in an IC memory card 3 (ROM or RA).
M) is inserted and is connected to the central processing unit 1. The main processing contents of the central processing unit 1 are calculation of various data obtained from the GPS receiving unit B, L
Displaying map figure data on the display unit 4 by a CD (liquid crystal display plate), displaying the current position, storing the data in the memory 2 and transferring the data to the wireless transmission unit C. Further, the display unit 4 is provided on the surface of the computer body 10 and the map information is displayed as graphic data.

The GPS receiving section B has a GPS antenna 5
And a GPS receiver 6, the GPS receiver 6 being connected to the central processing unit 1 of the computer section A,
Various data is input. The GPS receiver B is provided side by side on the computer body 10. That G
The radio waves from the artificial satellite received by the PS antenna 5 are GP
The S receiver 6 converts the data into position information, time information, speed information, altitude information, and heading information. The various types of converted data are input to the central processing unit 1.

The wireless transmission unit C is composed of a wireless transmitter 7 and a transmission antenna 8, the wireless transmitter 7 is connected to the central processing unit 1, and the wireless transmission unit C is the computer main body. Built in 10. Various data stored in the central processing unit 1 are transferred to the wireless transmitter 7, and various data are transmitted from the transmitting antenna 8.

Reference numeral 9 denotes a battery, and the operating power supply to each processing unit of the computer unit A, the GPS reception unit B and the wireless transmission unit C and the power supply for holding the memory 2 are all supplied. Has been done. The computer body 1
On the back surface of 0, a lid and a storage portion for storing the battery 9 are provided. The computer unit A, GPS receiving unit B, and transmitting unit C are configured so that the device can be made smaller and lighter and can be carried in a pocket of clothes.

To explain the operation of the present invention, first,
The radio wave from the artificial satellite received by the GPS antenna 5 is G
With the PS receiver 6, position information, time information, speed information,
Converted to altitude information and heading information. The converted data is converted into XY coordinates represented by latitude and longitude by a program stored in the memory 2 of the central processing unit 1, and its position is plotted and displayed on the map data displayed on the display unit 4. To be done.

If the calculated point is outside the range of the map area displayed on the screen of the display section 4, the map data of the area including the point is read from the IC memory card 3 and the screen of the display section 4 is displayed. After displaying in, plot the position. In this way, the current position information obtained from the GPS receiving unit B is displayed as a position mark on the map of the screen of the display unit 4, so that the current location of oneself can be easily recognized. .

Simultaneously with the confirmation of the current position, this position information is transmitted to the personal computer 20 from the wireless transmitter 7 and the transmitting antenna 8 built in the computer body 10. Specifically, the memory 2 of the central processing unit 1 displays the current position, registers and stores the information obtained from the GPS receiver 6 in the memory 2, and stores the information in the wireless transmitter of the wireless transmitter C. Data is transmitted from the transmission antenna 8 by transferring the data to the transmission antenna 7. That is, the data transmitted from the wireless transmission unit C is taken into the personal computer 20 via the wireless modem 21 connected to the personal computer 20. The captured data can be displayed on the screen of the CRT 22 to show the current position of the person who carries the portable current position transmission device. Further, by holding the data on the disk, it becomes possible to freely perform the data processing.

[0012]

According to the first aspect of the invention, the GPS receiving unit B receives the radio wave from the artificial satellite and converts it into the data of the position information, the time information, the speed information, the altitude information and the traveling direction information.
