Tracking method for cell phone with positioning device and system thereof
First Claim
1. A tracking system for a cell phone with a positioning device to transmit longitudinal and latitudinal coordinates contained in a plurality of position coordinate signals obtained from a global positioning system (GPS) from a tracked end to a tracking end via the short message service (SMS), comprising:
- a GPS receiving module for receiving the position coordinate signals transmitted from a plurality of satellites;
a central processing unit (CPU) for converting the position coordinate signals into the longitudinal and latitudinal coordinates, and encoding and decoding a positioning short message containing the longitudinal and latitudinal coordinates; and
a global system for mobile (GSM) communications module for transmitting and receiving the positioning short message.

Abstract
A tracking method for a cell phone with a positioning device and the system thereof are described. The longitudinal and latitudinal coordinates of a tracked end in a global positioning system (GPS) are sent to a cell phone of a tracking end via a short message service (SMS). After decoding the short message contents, the longitudinal and latitudinal coordinates are displayed in a geographic information system (GIS) installed in the cell phone.
