[amsat-bb] STS-99 Keps and CVITK

["Peter A. Klein" <pklein@xxxxxxxxxx>]

The STS-99 keps Paul mentioned at

>http://www.amsat.org/amsat/sarex/orbit.html

don't seem to work with CVITK without a little editing.  I tried converting
them with CVITK and loading them into InstantTrack. I got an epoch time of
1.00000, which led to a satellite that was orbiting the earth a couple of
thousand km underground.  :-)  Loading the two-line elements into STSPLUS
seemed to work.  

Here's the first line of the keps in question:

1 26088U 00010A      44.12741348  .00074667  23011-7  53783-4 0    55

Notice all the blank space just before the epoch time "44.12741348".  When
I replaced three leading blanks with three leading zeros, then I got the
proper epoch time out of CVITK.  I ran a test using both IT and STSPlus on
the next few passes, and the two programs agreed within a few seconds.

Here are the keps "corrected" for CVITK:

STS-99      
1 26088U 00010A   00044.12741348  .00074667  23011-7  53783-4 0    55
2 26088  57.0094 300.5820 0011888 288.7189 240.9083 16.15092467   230

Hope this is useful!
