 A major task in early phases of the design of a space mission is the optimisation of orbit characteristics on basis of parameter variations. This paper investigates the use of MATHEMATICA to compute orbits and their related properties, as well as the visualization of the results of parameter variations. Particular emphasis is placed on the analysis of the eclipsed periods. The application background for this paper is provided by the concrete examples of ABRIXAS and EUVSAT, two space missions studied within the German programme for small satellites.
