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/.
