Greetings,
Well, in all seriousness, Who would like to post a set of keps for one (or all) of the amateur satellites now flying using the methods pioneered by Karl Meinzer, DJ4ZC and James Miller, G3RUH?
I recall a few weeks ago someone decrying the lack technical discussion on the board.
...Well, here go you folks!

Hi Armando, N8IGJ
If unlikely AMSAT will be oblijed to derive by itself keps for the OSCAR satellites carrying a transponder using the following method:
or the GPS method:
ftp://rsd.gsfc.nasa.gov/pub/chesters/goesref/Moreau_GPS.pdf
the keps will be posted here for free in the hope to get more satellite users and AMSAT members.

Hi Armando et al,
I don't know about the methods written up by Karl & James. For a long time I've had a project using Doppler shift curves in the back of my mind (the "target" doesn't need to cooperate). I have most of the hardware based around my HPSDR box and a t'bolt frequency reference. The software hasn't even progressed beyond ideas and algorithms. I haven't even picked a language or development environment (one day).
I can see a very accurate Doppler shift curve being useful in the early days after a multiple cubesat launch. How accurate would you need to be to pick "your" cubesat from the crowd? One pass? multiple passes?
Anyway that's this morning's breakfast coffee ideas from me. Have fun y'all :-).

Hi folks,
The Celestrak web site has some great in depth stuff on keps and tracking. I think most people just drop onto the site to get the keps, but its certainly worth a more detailed look.
A big thank you to Dr. Kelso for a great site.
