PROBLEM TO BE SOLVED: To provide a compact terminal device recognizing positions of all kinds of mobile objects. SOLUTION: Although almost all positional information data obtained by utilizing conventional GPS electric waves are transmitted and received through electric waves used for commercially sold cellular phones after processing the information data, this terminal device is a technological product which enables the transmission/reception to be carried out, by using electric wave bands opened free of charge to the public in Japan. The product is useful to quickly solve incidents, accidents or the like in various fields. COPYRIGHT: (C)2006,JPO&NCIPI |
