FIELD: space communications engineering. SUBSTANCE: orbital satellites project outlines of directivity patterns onto earth. Each outline 30 of directivity pattern is divided into cells. Outlines of directivity patterns of adjacent satellites cover each other and this coverage increases when satellites approach pole from equator. Positions of all cells generated by all satellites are modeled by many dots over entire orbit. Channel groups are assigned to all cells within reference outline of directivity pattern. Mentioned assignment concerns all outlines of directivity pattern except for outlines 30 abutting against one side of orbit-to-orbit joint where satellites move in opposite directions. Channel groups are assigned near joint in response to channel groups assigned earlier. Each satellite memorizes channel groups assigned to its cells at different points over entire orbit. All satellites change over their communication parameters simultaneously in response to channel group assignment. In this way, provision is made for multiple use of spectrum on spherical surface, such as that of earth. EFFECT: improved channel power that specifies fixed frequency spectrum. 24 cl, 18 dwg
