An overview of air-bearing spacecraft simulators is provided. Air bearings have been used for satellite attitude determination and control hardware veri cation and software development for nearly 45 years. It is interesting to consider the history of this technology: how early systems were rst devised and what diverse capabilities current systems provide. First a survey is given of planar systems that give a payload freedom to translate and spin. Then several classes of rotational air bearings are discussed: those which simulate three-axis satellite attitude dynamics. The subsequent section discusses perhaps the most interesting facilities: those that provide both translational and three-dimensional rotational freedom. The diverse capabilities each style of air-bearing testbed provides, the many settings they can be found in, and ways to improve facility performance are described.

“…The centralized coordination approaches have been examined in detail [5][6][7][8][9][10][11][12][13]; however, there are still gaps in the decentralized coordinated attitude control literature [4,[14][15][16][17]. The most notable gap is the lack of a decentralized coordinated attitude controller that guarantees global convergence of the spacecraft formation.…”

The problem of controlling the attitude of spacecraft within a formation is investigated. A class of decentralized coordinated attitude control laws using behavior-based control is developed. The decentralized coordinated attitude control laws that comprise the class differ by the coordination architecture used by the spacecraft formation. The choice of behavior weights defines the coordination architecture. A corollary of Barbalat's Lemma is used to prove that the class of control laws globally asymptotically stabilizes the spacecraft formation. Convergence of the system is shown to be a consequence of the closed-loop equations of motion. Numeric simulation is used to reinforce the analytic results, and to briefly investigate the effect of coordination architecture on performance.
