Abstract: 각 위성마다 수신장치의 초기화 설정 값을 입력받아 3차원 형태의 버퍼로 저장하고, 관련된 모든 수신장치의 초기화를 3차원 초기화 버퍼를 이용하여 순차적으로 수행하고, 각 초기화 항목마다 수신장치의 초기화 이벤트 설정과 연동하고, 각 수신장치가 정상적으로 초기화되었는지 확인하는 것을 포함하는 3차원 버퍼와 이벤트 설정을 이용하여 위성 데이터 수신에 필요한 수신장치의 초기화 방법을 개시한다. 위성 데이터를 수신하기 위해서는 관련 수신장치의 초기화가 반드시 필요하고 상황에 따라서는 빠른 시간 내에 초기화를 완료해야 하는데, 개시된 수신장치의 초기화 방법은 3차원 버퍼와 이벤트 설정을 이용하므로 초기화 시간을 단축시킬 수 있다.

Abstract: PURPOSE: An active transponder is provided to simply move and assemble by modularizing a minimum number of components. CONSTITUTION: An active transponder comprises a rotary positioner (280) with two shafts, a body (230), multiple antennas, and a battery (250). The rotary positioned with the two shafts is installed at a position where three shafts of a tripod are met and has two elevator shaft supports. The body is coupled to one end of the elevator shaft supports. The antennas are connected to the body. The battery is mounted among tripod legs and supplies power to the body. The body comprises a transceiving and signal monitoring sub system, a driving system, and a power and control sub system. The transceiving and signal monitoring sub system monitors internal signals at regular time intervals. The driving system converts the direction of the active transponder. The power and control sub system supplies power and control signals to the transceiving and signal monitoring sub system and the driving system.
