We compared suitable repeat orbits from several aspects: temporal evolution of the groundtrack coverage; homogeneity of the groundtrack grid; stability with respect to variations in the mean altitude; proximity in altitude of orbits with shorter repeat periods (cycles and subcycles of the repeat orbits). While the analytical computations are capable of showing a broad picture of the possible orbital configurations, the precise simulations based on numerical orbit integration accounting for various perturbations allow us to include the most realistic orbital conditions, which have to be taken into account for the final decision about the orbit choice and fine orbit tuning (small changes in height of satellite orbit). We formulated suggestions that might be useful in the planning of the forthcoming measurement operational phases of GOCE gradiometer.
