[amsat-bb] Re: SRMSAT Keps and Down Link Details

[Lynn W. Deffenbaugh (Mr)]

I put the TLE from below into a satellite tracking program and the 
anticipated track over the past 12 hours or so can be viewed at

http://tinyurl.com/66ddu6d

Of course, the satellite isn't on orbit yet, but I thought a preview of 
the TLE-predicted track might prove interesting.
