본 논문은 위성항법지상국시스템 개발을 위하여 시스템 요구사항 정의, 시스템 구성, 시스템에 대한 주요 파라미터별 요구사항 도출 및 분석 결과를 기술한 논문이다. 위성항법 지상국 시스템은 항법 위성인 GPS와 Galileo 위성으로부터 항법 신호를 감시하는 신호감시국과 처리된 위성항법 데이터를 갈릴레오 위성으로 송신하는 상향링크국, 신호감시국 및 상향링크국을 구성하는 장비들에 대한 감시 및 제어기능을 수행하는 감시 및 제어시스템으로 이루어진다. 신호감시국은 항법 수신기와 원자시계, 기상정보처리 및 항법데이타 처리를 담당하는 서브시스템으로 구성되며 항법 수신기는 GPS와 Galileo 위성으로부터 항법 신호를 수신할 수 있는 복합 수신기 형태가 된다. 신호감시국은 항법 정보에 대한 보정정보처리을 위해 위성항법 제어센터인 GCC(GNSS Control Center)와 인터페이스 될 수 있어야 한다.
