Abstract

The DGPS reference station is a national infrastructure generating GPS correctional information and transmitting the signal for Differential GPS. Currently, Korea has applied and operated the software-based DGPS reference station as a standard of the next generation proposed by the USCG in order to improve the hardware-based DGPS reference system. However, software-based DGPS reference station proposed by USCG was changed in software method, only for form. There is no advantage to changing software-based because the most critical part of architecture has not been improved. In this paper, we have designed a new software-based marine DGPS station architecture that a reference station software and a monitor station were integrated. The new marine DGPS station architecture based on software is a more simplified structure than it used to be and can be utilized in the DGPS reference station.

DGPS 기준국은 Differential GPS를 위한 GPS 보정정보를 생성하고 방송하는 역할을 하는 국가 인프라이다. 현재 한국에서는 과거 하드웨어 기반의 DGPS 기준국 시스템을 개선하고 고도화하기 위해 USCG에서 제안한 차세대 표준인 소프트웨어 기반 DGPS 기준국을 도입하여 운영하고 있다. 그러나 USCG에서 제안한 소프트웨어 기반의 DGPS 기준국은 그 형태만 소프트웨어 방식으로 변경되었을 뿐 본질적인 아키텍처는 상당부분 개선되지 않아 소프트웨어 기반으로 변경한 장점을 크게 살리지 못하고 있다. 본 논문에서는 보다 간결화된 구조가 요구되는 DGPS 기준국에서 사용될 수 있는, 기준국 소프트웨어와 감시국 소프트웨어가 통합된 새로운 소프트웨어 기반 해양 DGPS 기준국의 아키텍처를 설계하였다.
