NOTICE: In an effort to minimise 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 this week "POEM 4 (BGS ARPIT)" was added where "POEM 4" is the name that appears in the USSF Satellite Catalog, and "BGS ARPIT" is the name best known within the amateur satellite community. Expect name changes for affected satellites whe in the ...Continue Reading
