International Designator

International Designator is a naming convention for satellites that consists of a three-part code. The first part is a two-letter country code that represents the country that launched the satellite. The second part is a two-digit year of launch, and the third part is a three-letter sequence number that represents the order of the satellite's launch within that year. The International Designator is used to uniquely identify satellites and track their orbital parameters. It is assigned by the United States Space Command (USSPACECOM) and is recognized by the International Telecommunication Union (ITU).
