Abstract
One purpose of this paper is to recall the mathematical procedures which can be used for integrating ordinary nonlinear differential equations. Actually, in digital computations matters such as machine memory and running time, have to be weighted against accuracy and stability and different procedures should be employed even for a given system following the class (i.e. the accuracy and running time) of the expected results. Accordingly, the main aspects embedded in integrating methods based on local polynomial approximation are discussed to some extent, and first order stability conditions for the numerical procedures are worked out simply by applying the well known z-transform.
The second purpose of the paper is to present the basic analytical support for the maneuvers of attitude and the orbital corrections for a spin stabilized satellite. To that end the reference dynamic equations are first established and the basic applied control is discussed. This brings an example computation of great importance since solution accuracy and computer running time must both be optimized. An adapted Hamming procedure with variable steps seems the best mate to the problem, being about twice less time-consuming than an equal-accuracy iterative Runge-Kutta algorithm.
