Subj: Changes to AMSAT TLE Distribution for March 28, 2025
Path: IZ3LSV<I0OJJ<EA2RCF<ZL2BAU<WG3K
Sent: 250330/1445Z 15715@WG3K.#SMD.MD.USA.NOAM LinBPQ6.0.24
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/

The following satellite has been removed from this week's AMSAT TLE
distribution:
KSU-Cubesat NORAD Cat ID 47954 Decayed from orbit on or about 21 March 2025
Provisional elements for the upcoming Fram2Ham mission have also been added
courtesy of ARISS, and will be updated when the SpaceX Dragon vehicle
attains orbit. Predictions based on these elements will be invalid if the
launch is delayed past the planned 01 April 2025 03:20 UTC liftoff or if
launch vehicle performance is off nominal. Updates will be found at
www.amsat.org/tle/dailytle.txt as appropriate.
