세계 해상 조난 및 안전제도(GMDSS)의 도입으로 해상에서의 조난통신 방식이 기존의 음성 전화에 의한 조난통신방식에서 디지털선택호출(DSC) 장치에 의한 조난통신 방식으로 변함에 따라 허위의 조난신호가 다량으로 발생하고 있다. 이러한 허위의 조난신호는 효율적인 수색구조에 막대한 영향을 미치고 있어 시급히 개선이 요구되고 있다. 이러한 문제점을 해결하기 위하여 국제해사기구에서는 허위 조난신호 경감을 위한 관련 결의서 및 권고안을 작성 유포하는 등 지난 10여 년 동안 많은 노력을 기울였으나 허위의 조난신호는 감소하고 있지 않다. 우리나라의 경우에도 구난무선국에 의해 접수된 조난신호 중 90% 이상이 허위 또는 미확인 신호로 판명되고 있어 심각한 상황을 나타내고 있다. 이러한 허위의 조난신호는 대부분 테스트 과정이나 사용자의 조작 실수에 의해 발신되는 것으로 나타나고 있다. 특히 디지털선택호출 장치에 의한 허위의 조난신호가 다량으로 발생함으로써 세계 해상 조난 및 안전제도의 정착에 많은 어려움을 야기하고 있다. 따라서 본 논문에서는 허위 조난신호 현황을 세부적으로 분석하고 허위의 조난신호가 다량으로 발생하고 있는 원인에 대하여 분석하였으며, 이러한 허위의 조난신호 경감을 위한 해결 방안을 제시하였다.

The distress communication system in the maritime mobile service had almost depended on the wireless telephony or telegraphy technique. The GMDSS (Global Maritime Distress and Safety System) which was introduced in 1992 brought a lot of changes in the maritime distress communication service such as the automatic transmission of distress signals and implementation of global search and rescue networks. However, there are some deficiencies in the GMDSS distress communication system such as a lack of compatibility in the maritime distress communication between CMDSS ships and Non-GMDSS ships, increasing deceptive or false distress alerts generated by GMDSS installations, lack of understanding about the CMDSS installations for the operators. In this paper, the problems of distress communication system in the maritime mobile service are analyzed and the methods to solve or minimize these problems are suggested.

COSPAS-SARSAT is the search and rescue system for providing a distress alarm and a position identification using an international satellite and ground facilities. Aviators, mariners and land users worldwide are equipped with COSPAS-SARSAT distress beacons, which could help save their in emergency situations anywhere in the world. As the existing COSPAS-SARSAT system is generally operated by LEO(Low-altitude Earth Orbit) Satellite System, the time from the distress beacon to the rescue is more than 1 hour with average and the accuracy of the distress location is about 5 Km. Therefore, in order to overcome this problem, the development for the next generation SAR(search and rescue) system which uses the MEO(middle-altitude Earth Orbit) satellites is going on the Galileo project. EU is developing this project for the full operation capability in 2011, and this project will have SAR payloads and support to the Search and Rescue service-herein called SAR/Galileo. SAR/Galileo will have the performance of a few meter accuracy, within 10 minutes to rescue from reception of distress messages, and Return Link Service(from the SAR operator to the distress emitting beacon), thereby facilitating more efficient rescue operations and helping to reduce the rate of false alerts. As the disaster is larger every year, the ground station, MEOLUT for next generation ASR/Galileo is urgently needed for the lifesaving for the larger disaster, the research for beacon and the ground station such as MEOLUT for introducing the next generation SAR/Galileo in Korea is very timely and is important. This paper presents the procedures and the strategies for the participation, the area to develop reasonably, and the propulsion organization for developing the SAR/Galileo ground system in Korea.
