Satellite constellations designed to observe a given belt upon the Earth's surface with minimum revisit time are discussed. The constellations consist of satellites in elliptic orbits. The Earth's flattening is taken into account in the satellite motion model. The transformations of the satellite motion initial conditions conserving revisit time are analysed. Based on the analysis the class of kinematically regular constellations is constructed. The solution of the optimization problem is sought in the class. The computational algorithm is described. Exemplary numerical results for the Australia-wide terrestrial belt are given. The results reveal that elliptic constellations can provide revisit time up to 24% less then the circular ones with the same inclinations and semimajor axes.
