Abstract

SIGMA(Scientific cubesat with Instruments for Global Magnetic field and rAdiation) CubeSat has been developed for magnetic field measurement of the Earth and space radiation measurement at Kyung Hee university. The flight software plays important roles in controlling the satellite and processing the data in the space mission. In this paper, the Flight Software has been implemented to process all the tasks in the one thread without RTOS(Real Time Operating System). This is an effective mothed not only to concentrate the space mission of CubeSat but also to reduce the overhead of the Flight Software by considering the mission perform procedures and the system control methods.

SIGMA(Scientific cubesat with Instruments for Global Magnetic field and rAdiation) 큐브 위성은 근 지구 자기장 세기와 우주 방사선량 측정을 위해 경희대학교에서 개발한 초소형 인공위성이다. 우주 임무 수행을 위해 비행 소프트웨어는 위성을 제어하고 데이터를 처리하는 중요한 역할을 담당한다. 본 연구에서는 SIGMA 큐브위성의 임무 수행을 위해 비행소프트웨어를 구현한 것으로서 일반적으로 임베디드 시스템에서 사용하는 실시간 운영체제를 사용하지 않고 단일 프로세스 내에서 모든 태스크를 처리하도록 구현하였다. 이는 SIGMA 큐브위성의 임무 수행 절차와 시스템 제어 방법을 고려한 것으로서 소프트웨어의 오버헤드(overhead)를 낮추고 임무 수행에 집중할 수 있는 효과적인 방법이다.
