해양안전정보 제공을 위한 DGNSS 기준국 기능개선 연구

Abstract

To assist the safety in various maritime activities such as construction, recreation, survey, rescue, fishery, sailing, it is necessary to provide the maritime safety information. That information mainly include the weather, tidal, accident, position accuracy reliability information. To provide that information, a particular system that can broadcast to all maritime area is needed. To generate and provide the maritime safety information, each Reference Station should be upgraded. For the purpose that, in this paper, we analyze and upgrade the design of the software architecture of DGNSS’s operation software. We identified and categorized the important information to make maritime safety information and data message protocol which will be broadcasted through the medium frequency wave. DGNSS Reference Station software was modified based on the designed software architecture and data message protocol in this paper. Also the software was installed and experimented successfully in a DGNSS Reference Station of Republic of Korea , position accuracy reliability information. To provide that information, a particular system that can broadcast to all maritime area is needed. Republic of Korea established 17 DGNSS Reference Stations infrastructure which can cover the whole country territories and waters. To generate and provide the maritime safety information, each Reference Station should be upgraded. For the purpose that, in this paper, we analyze and upgrade the design of the software architecture of DGNSS’s operation software. We identified and categorized the important information to make maritime safety information and data message protocol which will be broadcasted through the medium frequency wave. DGNSS Reference Station software was modified based on the designed software architecture and data message protocol in this paper.
