저장된 위성의 상태자료는 과거의 특정 시간에 수신된 상태자료를 재생시켜 보거나, 상태자료의 값을 추출해 보거나, 상태자료의 값이 변화하는 경향을 분석해 보기 위해 후처리하는데 사용한다. 전자파일 형태로 저장된 상태자료를 검색하여 원하는 구간의 데이터를 찾기 위해서는, 저장된 파일의 시간 태그 정보를 읽고 비교하여 원하는 데이터를 검색하는 방법을 사용한다. 그러나 저장된 파일의 처음부터 검색하는 방법은 원하는 데이터가 전자파일의 뒤쪽에 포함되어 있을 경우 검색에 많은 시간이 소요되는 문제가 있다. 또한 데이터베이스를 이용해 별도의 검색을 위한 자료를 생성해 검색에 활용하는 방법은 자료 관리에 드는 부담이 있다. 본 논문에서는 저장된 상태자료로부터 빠르게 원하는 상태 정보를 찾아내기 위한 방법을 제안한다.
