Abstract

This paper describes the integration and implementation of a satellite flight simulator based on an air bearingsystem, which was designed and instrumented in our laboratory to evaluate and to perform research in the field ofAttitude Determination and Control Systems for satellites, using the hardware-in-the-loop technique. The satelliteflight simulator considers two main blocks: an instrumented mobile platform and an external computer executingcostume-made Matlab® software. The first block is an air bearing system containing an FPGA based on-boardcomputer 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, whichruns in parallel Matlab® based algorithms for attitude determination and control. Both blocks are linked by meansof radio modems. The paper also presents the analysis of the satellite flight simulator dynamics in order to obtainits movement equation which allows a better understanding of the satellite flight simulator behavior. In addition, thepaper shows experimental results about the automated tracking of the satellite flight simulator based a virtualreality model developed in Matlab®. It also depicts two different versions of FPGA based on-board computersdeveloped in-house to integrate embedded and polymorphic digital architectures for spacecrafts applications.Finally, the paper shows successful experimental results for an attitude control test using the satellite flightsimulator based on a linear control law.
