ABSTRACT:
Disclosed is a complex multifunction system of a frequency band (130 dBm) frequency extension modulation of a GPS terminal in a life jacket which is used when there is an accident at sea, at a ship or at an airplane. The system comprises a body including a front plate which transmits and receives a frequency transferred from the GPS terminal in a life jacket in a process of introducing and sharing a coupling scheme with interspace-VLBI in frequency band 130 dBm, and a rear plate which is in contact with a tag of an HDX frequency extension modulation; a head unit for attaching a iris on a head of the body and supporting a frequency propagation amplification transmission of a microstrip fetch antenna; and a location based service (LBS) attached to a middle portion of the front plate of the body or a head unit, having a function of transmitting an emergency rescue signal and converting the signal into a multi-language voice information service.
