Abstract

A peer-to-peer global positioning system includes at least one location aware device to store position data. The at least one location aware device includes a first data transmitter and a first data receiver. An electronic device has a second data transmitter and a second data receiver. The second data transmitter transmits a position data request to the first data receiver. A memory storage device to store position data transmitted from the first data transmitter and received by the second data receiver.

Claims

1. A position coordinate acquisition apparatus in an electronic device, comprising:

a transmitter which transmits a position request signal,

a receiver which receives a position response signal, wherein the position response signal contains position coordinates;

a processing device which determines the position coordinates of the electronic device, wherein if more than one position response signal is received within a predetermined length of rime, the processing device determines the position coordinates based upon predetermined criteria; and

a storage device which stores the position coordinates of the electronic device.

2. The apparatus according to claim 1, wherein at least one of the position request signal and the position response signal is transmitted via wireless communication.

3. The apparatus according to claim 2, wherein the position request signal and the position response signal are transmitted via at least one of the following:

4. The apparatus according to claim 1, wherein the position coordinates include Global Positioning System (“

GPS”

) coordinates.

5. The apparatus according to claim 1, wherein the predetermined criteria includes at least one of the following:

(A) received position response signal strength;

(B) time when position response signal was received; and

(C) average of the more than one received position response signal.

6. A method of an electronic device acquiring position data, comprising:

transmitting a position request signal;

receiving a position response signal;

determining position coordinates of the electronic device, wherein if more than one position response signal is received within a predetermined length of time, a processing device determines the position coordinates based upon predetermined criteria; and

storing the position coordinates in a storage device.

7. The method of claim 6, wherein at least one of the position request signal and the position response signal is transmitted via wireless communication.

8. The method of claim 7, wherein the position request signal and the position response signal are transmitted via at least one of the following:
