초록

(주)쎄트렉아이는 고해상도 전자광학카메라 시스템, EOS-D Ver.1.0의 개발을 성공적으로 완료하였다. EOS-D Ver.1.0은 DubaiSat-2와 Deimos-2의 주 탑재체(main payload)로, 이 두 위성은 동사의 지구관측 위성 플랫폼(platform)인 SI-300을 기반으로 개발되었다. 두 위성의 발사 및 초기운용 후, 수분 발산에 의한 EOS-D Ver.1.0 광학계의 변형을 보상하기 위해 초점 조절(refocusing)을 수행하였다. EOS-D Ver.1.0 열제어계의 성능을 평가하고 신뢰성을 확인하는 동시에 설계 개선요소를 파악하기 위해, 초점 조절 전후 궤도상 비행 데이터를 수집, 분석하였다. 비행 데이터의 분석 결과, EOS-D Ver.1.0 열제어계가 설계 요구사항을 모두 만족하는 것을 확인하였다.

Satrec Initiative successfully developed a high-resolution electro-optical camera system, EOS-D Ver.1.0. EOS-D Ver.1.0 is the main payload of DubaiSat-2 and Deimos-2, which are developed based on the SI-300 platform of Satrec Initiative. After the launch and early operation (LEOP) of DubaiSat-2 and Deimos-2, we performed refocusing for the telescope of EOS-D Ver.1.0 to compensate for the dimensional change of its metering structure by moisture out-gassing. Before and after refocusing, we conducted the performance evaluation of thermal control system(TCS) for EOS-D Ver.1.0 using the in-orbit telemetry data. The evaluation showed EOS-D Ver.1.0 was under well-controlled thermal environment, which demonstrates TCS was designed and developed to meet all requirements.
