Mathematical models of the dynamics of spacecraft are needed to carry out numerical simulations, to gain insight into the characteristics of the spacecraft dynamics, and to synthesize control algorithms suitable for online system identification, estimation, and control. Increases in size and mechanical complexity of spacecraft result in increased complexity of the mathematical models. This results in turn in increased numerical simulation effort, increased difficulties in understanding the characteristics of the dynamics, and increased difficulties in synthesis and implementation of control algorithms. Reduction of the mathematical order of the open loop spacecraft dynamics model - with minimal loss of model accuracy - is therefore of paramount importance.
