Abstract The existence of families of periodic, repeat ground track orbits in full geopotentials is demonstrated. The basic families are made of almost circular orbits except in the vicinity of the critical inclination (63.4/116.6 deg), where the eccentricity of the repeat orbits grows for almost fixed inclination. Computation of specific repeat ground track orbits for mission design can be automated providing the nominal solution in a fast, straightforward way. We illustrate this with the computation of the TOPEX nominal orbit in a 140 × 140 truncation of the GRACE Gravity Model.
