For details see: www.amsat.org/keplerian-elements-formats/ A daily update of element sets is available at: www.amsat.org/tle/daily-bulletin.txt or witho ...Continue Reading

NOTICE: In an effort to minimize confusion between sources of two line element sets, AMSAT is adopting the convention of listing the USSF/NORAD Satellite Catalog name first, followed by any secondary name or names in parentheses. For example "POEM 4 (BGS ARPIT)" was added recently where "POEM 4" is the name that appears in the US Space Force Satellite Catalog, and "BGS ARPIT" is the name best known within the amateur satellite community. Expect name changes for affected satellites ...Continue Reading
