The purpose of carrier tracking and tracing is to achieve more information over shipments via carrying in mobile business. At multimodes, especially consignor wants to be aware of the exact situation and position of goods. As an innovative business model, we present CGPS(Carrier Global Positioning System) scheme using LEO(Low Earth Orbital) satellite. The LEO collects the data periodically and sends to the web server, and eventually customer's PC or PDA. This provides shipping company or freight forwarder with more robust information such as door status, container inside condition, etc.
