Abstract

A global position satellite (GPS) receiver constructed with a close range wireless communication port to facilitate the down loading of processed global p signal and to facilitate the communication between a handheld computing device and the GPS receiver. The handheld computing device is adjacent to the GPS receiver with close range wireless communication port to obtain processed position information from said GPS receiver.

Claims

1. A machine for providing position reference information of an automobile through wireless communication link comprising

a. a global position receiver;

b. a wireless communication converter circuit with a transmission range substantially close to a physical range of a parking lot of common walking distance;

whereby said global position receiver receives ranging information from global positioning satellites and processes to obtain position reference information, whereby said position reference information is packetized in digital format and transmits through said wireless communication converter circuit.

2. In claim 1 where said machine is secured in said automobile and where said wireless communication converter circuit transmits within said automobile.

3. In claim 1 where said close range wireless communication converter is an infrared communication port.

4. In claim 1 where said close range wireless communication converter is a short distance radio frequency port.

5. A method to obtain instant position information through a wireless arrangement inside an automobile comprising:

a. a global positioning receiver with a wireless transfer port secured on said automobile where said wireless transfer port communicates wirelessly through a physical distance substantially equivalent to a range of a parking lot of walking distance;

b. a portable computing device with complimentary wireless transfer port to said wireless transfer port of said global positioning receiver;

said global positioning receiver processes a position reference information and transmit to said portable computing device for subsequent processing and display by said portable computing device.

6. In claim 5 where said portable-computing device is a hand-held computer.

7. In claim 6 where said portable computing device displays said position reference information.
