Subj: Changes to AMSAT-NA TLE Distribution for May 2, 2025
Path: HB9ON<DK0WUE<PD0LPM<IR0AAB<VK2RZ<K1AJD<VE3CGR<WW4BSA<N3HYM<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, "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 in the coming weeks as this change is fully implemented.
This week there are no additions or deletions to the AMSAT TLE distribution.
[ANS thanks AMSAT Orbital Elementshttps://www.amsat.org/keplerian-elements-resources/ page for the above information]
