Satellites

GC number (Ground Control number, Russian: системный номер, номер по наземному комплексу управления) is the spacecraft number in almanac.[1] It only has to be unique during life time of each satellite. Numbers are subject to reuse. Some catalogs mistakenly used GC numbers for historical identification. See notes next to GC numbers.
