This paper presents the flight software of KoDSat (KSLV-l Demonstration Satellite) which performs demonstrating the KSLV-l (Korea Space Launch Vehicle-l)'s satellite launch capability. The KoDSat Flight Software executes in a single-processor, multi-function flight computer on the spacecraft, the OBC (On Board Computer). The flight software running on the single processor is responsible for all real-time processing associated with: processor startup and hardware initialization, task scheduling, RS422 handling function, command and data handling including uplink command and down-link telemetry, attitude determination and control, battery state of charge monitoring and control, thermal control processing.

This paper proposes the load distribution control allocation technique. The proposed method is designed by combining a conventional control allocation method with load distribution ability in order to reduce the stress acting on ailerons. By designing the weighting matrix as a function of the load distribution rule, the optimal deflection angles of each surface to satisfy both control goal and load distribution can be achieved. Moreover, rule based fault-tolerant control technique is also proposed. The rules are generated by considering both dominant control surfaces and the ratio of load distribution among surfaces. The performance of the proposed method is evaluated through numerical simulations.

항공기를 좋아하는 사람들에게는 누구나 어릴 적 추억이나 감명 깊게 본 항공영화가 하나쯤 있게 마련이다. 그리고 우리들 뇌리에는 탐 크루즈 주연의 탑건(TOPGUN)이라는 영화가 강한 인상으로 자리하고 있다. 하지만 영화는 배우들이 만들어낸 허구일 뿐, 실제 F-14 전투기의 공중전을 통해 조종사들의 생활과 애환을 다룬 작품은 따로 존재한다.
