Aspectos Construtivos de Bancadas Para Simulacao de Sistemas de Controle de Atitude de Satelites Artificais (Construction Aspects of Testbeds for Attitude Control Systems Simulation of Artificial Satellites)

摘要

This work presents the basic aspects concerning the construction of two test beds for satellite Attitude and Orbit Control Systems (AOCS) hardware-in-the-loop tests. The main goal to be reached with these test beds is the fast accomplishment of laboratory results in the various phaess of an AOCS development, from its initial conceptual definition to a prequalification phase. The central equipment of these test beds consists of a one-degree-of-freedom air bearing table and a two-degree-of-freedom servo rate table. Various AOCS components such as reaction wheels, cold gas jet propulsion system, telemetry/telecommand system and celestial simulators were also developed at INPE. The designs of the test beds as integrated equipments are presented. The main performance parameters and associated experimental results are presented and discussed as well.
