Betilde Muñoz-Pogossian,Tyler Finnmany purposes during the last two decades it has been possible to model the spacecraft as a rigid bodies or gyrostats, or perhaps simple two-body systems. However, even from the earliest days of real satellites, cases have been known where non-rigid characteristics have dominated the dynamical behav

María del Carmen Alanís Figueroagly, there is not a single correct approach to solution, but a spectrum of methods to be applied to a family of spacecraft idealizations. Although analysts will differ in their preference for various ways of formulating equations, one man choosing Lagrange’s equations, a second preferring Hamilton’s

María del Carmen Alanís Figueroaways. In Section 2.3 on substructure equations, it was assumed in order to focus that the substructure was a finite element system and the adjacent body was rigid, but this is a very special case. The procedure to be followed in developing equations for systems of substructures depends very much on

Nélida Archenti,María Inés Tulaor that solution, and these equations can always be used to provide matrix transfer functions among the variables, this approach is particularly fruitful when scalar transfer functions are extracted to relate the vehicle rotation about a given axis. Such transfer functions may be expected to provide
