I went here:

http://www.satellite-calculations.com/TLETracker/SatTracker.htm

It had the TLE for Galaxy 15 as follows:

GALAXY 15
1 28884U 05041A   10133.62484064  .00000085  00000-0  10000-3 0  8291
2 28884 000.1391 078.0756 0002640 331.8937 274.1784 01.00285599 16790

And did these calculations (using Calc on Ubuntu)

10133.62484064 - Thu May 13 2010 10:59:46 GMT-0400 (EDT) = Thu May 13 
2010 14:59:46 GMT

10 - 2010
133 - 133rd day (assume that's Thu May 13 - didn't check)

0.62484064 * 24 = 14.99617536
0.99617536 * 60 =  59.7705216
0.7705216 * 60 = 46.231296

Seems ok to me...

Replacing there time stamp in that web site with your example gives the 
same answer you got.  Either that web site is wrong, too, or your 
example was wrong.

Jeff.
