Abstract

Provided are an apparatus and method for transmitting/identifying a location based on local communication. The apparatus, includes: a location information calculating unit for receiving a Global Positioning System (GPS) signal from a GPS satellite and calculating location information; own location transmitting unit for transmitting a signal, in which the calculated location information and recognition information are inserted, through a local communication antenna; a counterpart location receiving unit for receiving a signal transmitted from another location transmitting/identifying apparatus located in a close range through the local communication antenna; and a counterpart location identifying unit for checking the received signal and identifying a location of another location transmitting/identifying apparatus.

Claims

1. A first location apparatus for identifying a location of a close object based on local communication, comprising:

a location information calculating means for receiving a Global Positioning System (GPS) signal from a GPS satellite and calculating a location of the first location apparatus based on the GPS signal;

own location transmitting means for transmitting a first signal directly to a second location apparatus via an ISM frequency band, wherein the second location apparatus is located within about three kilometers from the first location apparatus during the transmitting, and wherein the first signal comprises the location of the first location apparatus and recognition information of the first location apparatus;

a counterpart location receiving means for receiving a second signal directly from the second location apparatus via the ISM frequency band; and

a counterpart location identifying means for identifying a location of the second location apparatus based on the second signal,

wherein the own location transmitting means transmits information corresponding to a location of the GPS satellite directly to the second location apparatus via the ISM frequency band, and wherein the second location apparatus uses the information corresponding to the location of the GPS satellite to receive a GPS signal from the GPS satellite.

2. The first location apparatus of claim 1, further comprising:

a location output means for outputting the location of the second location apparatus on a digital map.

3. The first location apparatus of claim 2, further comprising:

a storing means for storing a name, a telephone number, and a vehicle registration number corresponding to the recognition information of the first location apparatus,

wherein the counterpart location identifying means identifies a name, a telephone number, and a vehicle registration number corresponding to the second location apparatus based on the second signal, and

wherein the counterpart location identifying means outputs the location of the first location apparatus, the name, the telephone number, and the vehicle registration number corresponding to the second location apparatus, and the name, the telephone number, and the vehicle registration number corresponding to the first location apparatus on the digital map.

4. The first location apparatus of claim 1, wherein the information corresponding to the location of the GPS satellite comprises orbit information and almanac information of the GPS satellite.

5. A method for a first location apparatus to identify a location of a close object based on local communication, comprising the steps of:

a) receiving a Global Positioning System (GPS) signal from a GPS satellite and calculating a location of the first location apparatus based on the GPS signal;

b) transmitting a first signal directly to a second location apparatus via an ISM frequency band, wherein the second location apparatus is located within about three kilometers from the first location apparatus during the transmitting, and wherein the first signal comprises the location of the first location apparatus and recognition information of the first location apparatus;

c) receiving a second signal directly from the second location apparatus via the ISM frequency band; and

d) identifying a location of the second location apparatus based on the second signal,

wherein the transmitting further comprises transmitting information corresponding to a location of the GPS satellite directly to the second location apparatus via the ISM frequency band, and wherein the second location apparatus uses the information corresponding to the location of the GPS satellite to receive a GPS signal from the GPS satellite.

6. The method of claim 5, further comprising the step of:

e) outputting the location of the second location apparatus on a digital map.

7. The method of claim 6, further comprising the step of:

f) storing a name, a telephone number, and a vehicle registration number corresponding to the recognition information of the first location apparatus in a storing means,

wherein the identifying comprises identifying a name, a telephone number, and a vehicle registration number corresponding to the second location apparatus based on the second signal, and

wherein the outputting comprises outputting the location of the first location apparatus, the name, the telephone number, and the vehicle registration number corresponding to the second location apparatus, and the name, the telephone number, and the vehicle registration number corresponding to the first location apparatus on the map.

8. The method of claim 5, wherein the information corresponding to the location of the GPS satellite comprises orbit information and almanac information of the GPS satellite.
