현재 한국에서 설치, 운영되고 있는 DGPS 기준국은 RTCM의 DGPS 기준국 관련 표준인 RSIM 버전 1.2를 기반으로 제작되어져 있다. RSIM 버전 1.2는 GPS의 보정정보를 생성하는 기준국을 위해 제정된 표준으로 현재의 다양한 GNSS들에 대한 보정정보를 서비스하는 것은 불가능하다. 이에 RTCM에서는 GPS외에 다양한 GNSS들을 지원할 수 있도록 새로운 기준국 표준 버전인 RSIM 버전 1.3을 제정하고 있다. 이러한 시점에서, 한국의 DGPS 기준국이 DGNSS 기준국으로 발전하여 각 GNSS의 보정정보를 서비스하기 위해 필수적인 신규 버전 기반 소프트웨어 RSIM 시스템을 개발하기 위해 본 논문에서는 RSIM 버전 1.3의 특징을 분석하고 소프트웨어 RSIM에서 구현되어야 하는 필수 기능들을 도출하였다.

The standard for DGPS reference station system defined by RTCM is in the current version of 1.2. This standard currently supports only GPS of the United States. However, the current operating GNSS satellite consisted of not only GPS, but also GALILEO of Europe, GLONASS of Russia, QZSS of Japan, BeiDou of China and so on. Therefore, the existing standard is not able to support them. Accordingly, a new standard in the version of RTCM's RSIM 1.3 is established in order to provide correctional services to GNSS satellites. In this paper, the version of RSIM 1.3 is analyzed and the software for DGNSS reference station architecture supporting the version of RSIM 1.3 is designed.

At present, available positioning satellites are not only the GPS, but also GLONASS, GALILEO, QZSS, BeiDou. However, the differential GPS, the augmentation service for increase the positioning accuracy, is follow the RTCM version 2.3 standard. So, it can service the correction information about only GPS. For solve this problem, RTCM is making the new version of RTCM message standard that can service the correction information for all of available GNSS. In South Korea, the software DGNSS RSIM system was installed at almost the whole DGNSS reference station. In this reason, that can cope with the new RTCM version 2.4 quickly. However, the DGNSS Reference Station based RSIM 1.3 can not make the GNSS's PRC simultaneously and can not support RTCM version 2.4. Thus, in this paper, the version of RTCM 2.4 is analyzed and the RTCM version 2.4 message generating module's architecture for software DGNSS reference station is designed.
