[amsat-bb] true tle

Dears. Merry Christmas. I wish all of you have happy holidays. I have question about true tle of amsat satellites. There is one set of TLE in celestrak and one in each satellite webpage in amsat . those are different from in clestrak. Which of these TLE are true that I can use in unitrak for tracking? My tracking predictions in following two pages are different. I don’t know why? http://www.amsat.org/amsat-new/tools/predict/index.php http://www.amsat.org/amsatnew/satellites/satInfo.php?satID=116&retURL=/s...

Any help would be gratefully appreciated. Best Regards.
