MULTIFUNCTION SPACE COMMUNICATION SYSTEM Russian patent published in 2007 - IPC H04B7/185 

FIELD: wide-range high-altitude communication systems incorporating satellite groups launched into different-altitude orbits and at least one ground-based control station.

SUBSTANCE: proposed system that has satellite group launched into geostationary orbit, satellite group injected into low-altitude orbit, and at least one ground-based control station is provided in addition with satellite group launched into medium-altitude orbit, at least one satellite disposed on geostationary orbit being connected through communication line with ground-based control station; satellites injected into geostationary orbit are interconnected via high-speed communication lines and are designed for relaying control signals from ground-based control station to satellites disposed on medium- and low-altitude orbits whereto they can be connected by means of communication line, and also for relaying information signals received from satellites disposed on medium- and high-altitude orbits to ground-based control station; each of satellites disposed on low-altitude orbit can communicate with at least one of satellites disposed on medium-altitude orbit and each of satellites disposed on this orbit, with one of satellites disposed on geostationary orbit.

EFFECT: provision for communications and monitoring at minimal quantity of space vehicles.
