Apparatus and method for processing position information
First Claim
1. A position information processing device, comprising;
- a GPS receiver adapted and configured to receive a first satellite signal including satellite signals from a first set of four visible satellites;
an interdevice communication receiver adapted and configured to receive, from a mobile phone, a second satellite signal including satellite signals from a second set of four visible satellites different from the satellite signals from the first set of four visible satellites;
a GPS information processor adapted and configured to compare the first satellite signal with the second satellite signal and generate a third satellite signal based on the first satellite signal and the second satellite signal, wherein the third satellite signal includes the satellite signals from the first set of four visible satellites and the satellite signals from the second set of four visible satellites; and
a navigation controller adapted and configured to use the third satellite signal to calculate coordinates of a current position.

Abstract
A position information processing device according to an exemplary embodiment of the present invention can include a GPS receiver adapted and configured to receive a first satellite signal, an interdevice receiver adapted and configured to receive a second satellite signal from a mobile phone, a GPS information processor adapted and configured to compare the first satellite signal with the second satellite signal and generate a third satellite signal for calculating a current position, and a controller adapted and configured to use the third satellite signal to calculate coordinates of the current position. The proposed position information processing device uses the satellite signal that is received from the mobile phone, and therefore the accuracy of the position measurement can be improved.
