| Abstract | Brazil, through INPE, is on its way to launch the first Scientific Applications Satellite, SACI-1 together with the China Brazil Earth Resources Satellite, CBERS-1. The SACI-1 intends utilization of one onboard autonomous attitude control made by magnetic coils put on the directions the principal axes of inertia, and using as sensors: a 3 axes magnetorricter and a 2 axes sun sensor. The simulation, implementation and validation of an autonomous control software into an onboard digital computer are innovations for Brazil and for INPE, and our anterior experience doesn't include them. This work, even general, takes for base the SACI-I characteristics and may contribute to development. It shows how to do the simulation and implementation of the digital control laws operating in real time that controls the spin axis direction as well as the satellite spin taking into account aspects of great importance, like: sampling periods; quantization size; duration of inputs, outputs and processing of the data, etc.; and their effects, like: attitude effors (angles and angular velocities); the limitations on the reference bandwidth to be tracked; etc. This work presents possibilities to do the simulation and implementation emphasizing the one that is being utilized. also shows the aspects related with data communication utilizing as interface the MEGAOUT SERIAL III board that contains 8 RS-232/C serial gates, and how to do its programming. |
