  • Publication number: 20110012782
    Abstract: An object position information tag apparatus, which is attached to an object and transmits position information of the object, includes a global positioning system (GPS) module for receiving a satellite signal from a GSP satellite and calculating the position information of the object and a communication module for transmitting data of the position information being input from the GPS module and a unique identification (ID) code being distinctive for each object to an external device through radio communication. Accordingly, it is possible to effectively recognize positions of products or equipment to which the tag apparatus is attached, regardless of the number and storage place of products or equipment, based on which information regarding movement, storage, and shipping of the open-air stored or stored products or equipment can be collectively gathered and managed.
