I'm the author of NASAWASH. It doesn't have that feature, though it would be a good starting point for a C programmer wishing to create such a program. If somebody added that feature already, I'm not aware of it (and the version on the AMSAT web/ftp site doesn't include it). Perhaps you're thinking of some other program you used in conjunction with NASAWASH?

If you have (or install yourself) a reasonably standard "grep" program (such as the one at http://gnuwin32.sourceforge.net/packages/grep.htm ) you can write a simple batch file script like this, assuming that you've already downloaded the elements from your favorite source to a file named inputfile:

nasawash inputfile nasabare.txt grep -A 2 AO-51 nasabare.txt >mynasa.txt grep -A 2 FO-29 nasabare.txt >>mynasa.txt grep -A 2 AO-07 nasabare.txt >>mynasa.txt grep -A 2 SO-67 nasabare.txt >>mynasa.txt

The "-A 2" tells grep to output the matching line and two lines following. The NASAWASH step is optional if the file you download contains nothing but the element sets.

THAT'S the one I was thinking of! It's been a long time since I've needed it...

In the same utilities directory is a program called SORTNENG which will extract specific satellites from a list of Keps. I use it in combination with NASAWASH in a batch file to send customized lists to the several tracking programs I use.

Looks like it's still available in the AMSAT software archive at http://www.amsat.org/amsat/ftp/software/PC/util/nasawash.zip

Hello everyone,

Is there a program or script that could automate the creation of a custom keplerian element list that includes satelites that i´m only interested in, from data from either either spacetrack or celestrack? My idea is to create something similar to the list that AMSAT publishes but more specific to my needs, meaning that there are some sats in there that I don´t care about.

I tried the TLEretriever but no cigar there, at least for the purpose in sight.
