　　The safety of human life in the maritime industry is carried out by taking intothe considerations which are proposed by the International Maritime Organization(IMO). When any emergency condition arises, there are

2、 certain set of rules whichshould be followed. The Global Maritime Distress and Safety System (GMDSS)describe those communication protocols which are meant to be carried out in thesituation where there is a threat to

3、human life, health, property or environment.
　　The emergency position indicating radio beacon (EPIRB) is an important partof the GMDSS systems which transmits a 406 MHz identification signal which isreceived by sea

4、rch and rescue satellite-aided tracking (SARSAT) satellites whichare in orbit around earth (GEOSAR and LEO satellite). The ground receivingstation relays the position coordinates for the EPIRB as well as identification

5、information relating to the vessel to which EPIRB was assigned. It is housed in abuoy which is designed to float on the surface of water, and the upper portion ofthe buoy includes an antenna cone which contains the tr

6、ansmitting antenna and inorder to aid in visual location of EPIRB by the SAR vehicles, the top of theantenna cone is provided with light.
　　The next generation of the EPIRB is software realized based on the theoret

7、icalfundamentals of software defined radio. The software based EPIRB and EPIRBtester has the same functionalities which are provided in the second generation406 MHz EPIRB and is developed in the research project. Thes
