1. A position coordinate acquisition apparatus in an electronic device, comprising:
- a transmitter to transmit a position request signal;
a receiver to receive a position response signal, wherein the position response signal contains position coordinates;
a processing device to determine the position coordinates of the electronic device, wherein if more than one position response signal is received within a predetermined length of time, the processing device determines the position coordinates based upon predetermined criteria; and
a storage device to store the position coordinates of the electronic device.

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.
