Hi,

In my experience, pre launch keps don't have a checksum. They just show the key numbers that define the orbit. My tracking software wont load them automatically. If you key them in manually it should work fine. You can then run the software and see how the passes will look for your QTH.

I did this for KYSat-1 on Instanttrack and it worked fine.

There are plenty of places on the net to find the make up of the NASA 2 line element set.

Curious, I just tried both the Cubesat.org and Henk's corrected Keps here on the computer at home and neither would work. I did the exact same thing at the schools computer earlier today and it worked fine.  --- On Thu, 3/3/11, Dave Webb KB1PVH [email protected] wrote:

I just tried using the TLEs off of the KySat-1 page, but couldn't get them to work, nothing showed up.

I was wondering too if it was the checksum. When the web page was created, the keps got pasted wrong. Use the Keps from the  cubesat.org page, they work.http://www.cubesat.org/

1 99999U 00000    11063.43259919 0.00000000  00000-0  00000-0 0  0000 2 99999  97.9564  8.4412 0007658  67.0214 113.6793 14.77265551000000If this copy does not work, go to the cubesat.org page.
