    This is a question that may be best answered by directing me to a website.
    (1) I am wondering how TLEs are produced so frequently for what seems to be
    an innumerable number of objects orbiting the earth.  Is it an automatic
    process one by telescopes and computers somewhere?
    (2)Who does it?
    Thanks for any help in this matter.
