Customize Real-Time Linux for Rocket Flight Control System - George Kang, Advanced Rocket Research Center, Taiwan

The flight control system for HTTP-3A rocket developed by ARRC in Taiwan is based on real-time Linux system, building rocket steering and attitude control under high dynamics environment. The major objective of HTTP-3A is to launch a sounding rocket vertically and send a 10 KG of payload with guidance and attitude control to an apogee exceeding 100 KM, while exercising all kinds of technologies of satellite launch vehicle, except the orbit insertion.

Flight control system is the crucial component of rocket avionics system. To its meet mission critical requirements, the flight control system is built on PREEMPT_RT based Linux along with hardware-assisted hard real time sensing and actuation. At present, sensing referring to sensor acquisition is accomplished by real-time capability of actuation, guaranteed by EtherCAT and PREEMPT_RT.
