Abstract

It requires a lot of time and effort for general users who do not have enough understanding of GPS to properly processing GPS data. However, the GPS data processing field heavily relies on foreign-produced software and there is almost no development of user-oriented technology. Therefore, in this study, it was attempted to build an expert service that enables non-experts to use high-precision GPS data processing. As a result, an expert service that can maximize user convenience simply by entering the minimum required information for GPS data processing was developed, and the expert service was verified by relative positioning processing of the observation data of satellite control point provided by National Geographic Information Institute and observation data obtained by GPS survey. The expert service significantly reduces the effort and time for processing GPS data, which will contribute to precise positioning and other various studies.

GPS에 대한 이해가 부족한 일반사용자가 정상적으로 GPS 자료를 처리하기 위해서는 많은 시간과 노력이 필요하다. 하지만 GPS 자료처리 분야는 외산 소프트웨어에 크게 의존하고 있으며, 사용자 위주의 기술 개발은 거의 이루어지지 않고 있다. 이에 본 연구에서는 비전문가도 상대측위 방법으로 고정밀 GPS 자료처리가 가능한 전문가 서비스를 구축하고자 하였다. 연구결과, GPS 자료처리에 필요한 최소 정보만을 입력함으로써 사용자의 편의성을 극대화시킬 수 있는 전문가 서비스를 개발하였으며, 국토지리정보원에서 제공하는 위성기준점의 관측자료와 실제 GPS측량으로 취득한 관측자료의 처리를 통해 전문가 서비스를 검증하였다. 전문가 서비스는 GPS 자료처리에 소요되는 노력과 시간을 크게 단축시킴으로써 정밀위치결정은 물론 다양한 학술연구에 기여할 것이다.
