This paper provides an overview of air-bearing spacecraft simulators. Air bearings have been used for satellite attitude determination and control hardware verification and software development for nearly 45 years. Honeywell Space Systems and Virginia Tech are each developing unique new facilities. During their development, we have become interested in the history of this technology: how early ...
In this paper, we deal with the attitude control of a satellite equipped with wheels of reaction, using the static output feedback. In the first part, we set the control and its integral in the state-feedback form. Then, by using the algorithm of Kucera, we establish the necessary and sufficient conditions so that the nonlinear system which models the satellite will be stabilizable by the Stati...
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 sy...

Satellite jitter has become a more and more important factor which affects the quality of imagery products with development of the high resolution satellite. This paper focused on analyzing the impact on multi-spectral image caused by satellite jitter and proposed a jitter detection and compensation method to improve the band-to-band registration efficiently when jitter exists without observati...
