Subj: Changes to AMSAT-NA TLE Distribution for January 10, 2024
Path: IZ3LSV<DB0ERF<DK0WUE<DK0WUE<VK5RSV<VK2RZ<KC9UHI<KA1VSC<WG3K

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/.
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 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 in the coming weeks as this change is fully implemented.
The following satellite has been added to this week's AMSAT TLE distribution:
POEM 4 (BGS ARPIT) NORAD Cat ID 46495
The following satellites have been removed from this week's AMSAT TLE distribution:
PRISM (HITOMI) NORAD Cat ID 33493 Likely defunct
YUBELEINY 2 (RS-40) NORAD Cat ID 33735 Likely defunct
CHUBUSAT-2 NORAD Cat ID 41338 Likely defunct
CHUBUSAT-3 NORAD Cat ID 41339 Likely defunct
PRATHAM NORAD Cat ID 41783 Likely defunct
D-SAT NORAD Cat ID 42794 Likely defunct
RANGE-B NORAD Cat ID 43772 Likely defunct
CySat-1 NORAD Cat ID 61501 Decayed from orbit on or about 09 January 2025
MRC-100 NORAD Cat ID 56993 Decayed from orbit on or about 05 January 2025
