. . "Spacecraft call signs are radio call signs used for communication in crewed spaceflight. These are not formalized or regulated to the same degree as other equivalent forms of transportation, like aircraft. The three nations currently launching crewed space missions use different methods to identify the ground and space radio stations; the United States uses either the names given to the space vehicles or else the project name and mission number. Russia traditionally assigns code names as call signs to individual cosmonauts, more in the manner of aviator call signs, rather than to the spacecraft."@en . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The only continuity in call signs for spacecraft has been the issuance of \"ISS\"-suffixed (or \"-1SS\", for its visual similarity) call signs by various countries in the Amateur Radio service as a citizen of their country has been assigned there. The first Amateur Radio call sign assigned to the International Space Station was NA1SS by the United States. OR4ISS (Belgium), GB1SS (UK), DP0ISS (Germany), and RS0ISS (Russia) are examples of others, but are not all-inclusive of others also issued."@en . . . . . .
