Abstract:
1. A complex multifunction system of a frequency band (130 dBm) frequency extension modulation of a GPS terminal in a life jacket, comprising: a body including a front plate, which transmits and receives a frequency transferred from the GPS terminal in the 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 an iris on a head of the body and supporting a frequency propagation amplification transmission of a microstrip patch antenna; and a location based service 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 multilanguage voice information service, wherein a modulation of radio wave propagation and a frequency propagation amplification are performed in the body and the head unit.
