| Resumo: | This paper describes the integrati on and implementation of a satellite f light simulator based on an air bearing system, which was designed and instrumented in our laboratory to evaluate and to perform research in the field of Attitude Determination and Control System s for satellites, using the hardware- in-the-loop technique. The satellite flight simulator considers two main blocks: an instrumented mobile platform and an external computer executing costume-made Matlab® software. The first block is an air bearing system contai ning an FPGA based on-board computer with capabilities to integrate digital architectures for data acquisition from inertial navigation sensors, control of actuators and communications data handling. The second block is an external personal computer, which runs in parallel Matlab® based algorit hms for attitude determination and contro l. Both blocks are linked by means of radio modems. The paper also present s the analysis of the satellite flight simulator dynamics in order to obtain its movement equation which allows a be tter understanding of the sate llite flight simulator behav ior. In addition, the paper shows experimental results about t he automated tracking of the satellite flight simulator based a virtual reality model developed in Matlab®. It also depicts two different versions of FP GA based on-board computers developed in-house to integrate embedded and polymorphic digital architecture s for spacecrafts applications. Finally, the paper shows successful experimental results for an attitude control test using the satellite flight simulator based on a linear control law. |
