The development of methods for the design of satellite constellations for continuous coverage is reviewed in this paper. The main notions and definitions involved in solving the problem of multifold continuous coverage of Earth and near-Earth space are described. The region to be observed is represented by a spherical layer, with the problem of continuous L-fold coverage of the layer reduced to continuous no-less-than-L-fold coverage of each of its spheres by the coverage areas. The mathematical setting and methodological principles for solving the problem of optimizing the orbital formation of multi-tiered satellite constellations for continuous coverage of near-Earth space are examined. The location of this problem in the general scheme of ballistic substantiation of space system design is indicated. A methodological solution pattern for optimizing the orbital formation of satellite constellations for continuous multifold coverage of near-Earth space within the class of kinematically regular mono-structures is proposed. It is shown that the solution of these constellation optimization problems is reduced to obtaining α-parameters of the systems and optimizing them for inclination, where the α-parameter is understood to be the minimal angular radius of the coverage areas that provide continuous L-fold coverage of the sphere.
