  • The use of satellite remote sensing in maritime safety and security can aid in the detection of illegal fishing activities and provide more efficient use of limited aircraft or patrol craft resources. In the area of vessel traffic monitoring for commercial vessels, Vessel Traffic Service (VTS) which use the ground-based radar system have some difficulties in detecting moving ships due to the limited detection range. A virtual vessel traffic control system is introduced to contribute to prevent a marine accident such as collision and stranding from happening. Existing VTS has its limit. The virtual vessel traffic control system consists of both data acquisition by satellite remote sensing and a simulation of traffic environment stress based on the satellite data, remotely sensed data. And it could be used to provide timely and detailed information about the marine safety, including the location, speed and direction of ships, and help us operate vessels safely and efficiently. If environmental stress values are simulated for the ship information derived from satellite data, proper actions can be taken to prevent accidents. Since optical sensor has a high spatial resolution, JERS satellite data are used to track ships and extract their information. We present an algorithm of automatic identification of ship size and velocity. This paper lastly introduce the field testing results of ship detection by RADARSAT SAR imagery, and propose a new approach for a Vessel Monitoring System(VMS), including VTS, and SAR combination service.

It lastly is shown that based on ship information extracted from JERS data, a qualitative evaluation method of environmental stress is introduced.

  • 본 연구에서는 선박의 충돌이나 좌초와 같은 사고의 예방에 기여할 수 있는 가상교통관제시스템의 개념을 소개한다. 지금의 VTS는 사고의 억지효과가 있음에도 불구하고, 그 한계점을 가지고 있다. 그래서 현 시스템을 광역 VTS개념으로 확대 시행하더라도 그 효과에 많은 의문이 발생할 수 있다. 가상교통관제시스템은 인공위성에 의한 해상환경의 리모트센싱과 여기서 얻어진 데이터에 기반을 둔 환경부하 모델(INOUE model)로 구성된다. 인공위성 리모트센싱은 선박, 기상, 해양 정보를 포함하는 대부분의 해상 교통 환경 정보를 제공해 줄 수 있다. 이들 정보를 이용해서 각 선박에 대한 환경 부하를 시뮬레이션 함으로써, 미래의 (예, 5분후) 교통환경을 예측하고, 교통제어를 할 수 있는 시스템을 제시한다. 마지막으로, 인공위성 데이터를 사용해서 선박정보를 추출하는 방법을 보여준다.
