Abstract: Lagrange's equations in quasicoordinates are usually used for dynamics modeling of spacecraft. This paper provides a formulation of Lagrange's equations in quasicoordinates for dynamics modeling of multi body flexible spacecraft based on the Hamilton's principle. From the derived equations the dynamic equation of flexible spacecraft with central body and flexible appendages is created.
