This technical brief presents a nonlinear dynamic model of Jupiter Icy Moons Orbiter (JIMO), a concept design of a spacecraft intended to orbit the three icy moons of Jupiter, namely, Europa, Ganymede, and Callisto. The work presented in this paper represents a part of a feasibility study conducted to assess control requirements of the JIMO mission. A nonlinear dynamic model of JIMO is derived that includes rigid body as well as flexible body dynamics. A nonlinear dissipative control law with guaranteed stability is used to perform a representative in-orbit maneuver. The results presented are part of an exhaustive study conducted to evaluate various controller designs.
