Hi All, Just updated keps for noaa weather satellites from Celestrak and find the the file contains mostltly birds that are no longer operational. How can I delete the unwanted birds. Thanks John G7HIA

Click MY COMPUTER then C (OS) then PROGRAM FILES then ORBITRON then TLE then noaa and edit that file and click SAVE.
You will need to do that every time you update your KEPS.

There used to be a program called NASAWASH that would allow you to clean up a TLE file by specifying, in a text file, which birds you were interested in, and then running the program against the new TLE file each time you downloaded it. It would then output a TLE file containing only the sats you specified. I think it was available for download from the AMSAT files area.

NASAWASH is still available at http://www.amsat.org/amsat-new/tools/softwareArchive.php#pc-util or direct from me at http://www.mustbeart.com/software/nasawash.html -- but it doesn't have that feature. It cleans up a TLE file but can't select a subset of the satellites.
There are a couple of other old DOS programs still available on the AMSAT web site that do have the feature. Follow the link above and look for EXTRACT or SORTNENG.

Oops, you're right... It was SORTNENG I was thinking of.

Using GNU grep 2.5.4 on Linux:
grep -F -f wanted.sat -A 2 weather.txt > use_this.tle
The file 'wanted.sat' is a simple text file with a list of desired satellites, one per line. Example (using amateur satellites):
----8<------------->8------ OSCAR 7 EYESAT-1 JAS-2 PCSAT HAMSAT ----8<------------->8------
Grep picks any satellites that matches your listed names, and outputs the name and the two-line data immediately following. It adds a separator line between each, but I've never had a problem. AAMOF (and correct me if I'm wrong) but the TLE format is specifically supposed to ignore additional lines that don't conform to the TLE format.
Not running Linux? Start today! ;-)
Or, look for 'grep' for Windows here:
