classfd cruft

Crufty scriptlets for poking at Mike McCants' classfd.tle.

• https://spacecruft.org/spacecruft/classfd-cruft

Setup

Using Debian Stable (12/bookworm).

Upstream compresses files using zip, so that is needed:

apt install unzip

To run the sattools scripts, install this:

• https://spacecruft.org/spacecruft/sattools

Scripts

What the little scripts do:

• classfd-dl --- Downloads and unzips Mike McCants' classified elements.
• classfd-ls-ids --- Lists NORAD IDs in Mike McCants' classified elements.
• spacecruft-classfd-all --- Runs all the scripts in proper order.
• spacecruft-classfd-ls-ids --- Lists NORAD IDs in the Spacecruft archive also in the McCants' classfd list.
• spacecruft-classfd-missing-ids --- Lists classfd IDs not in Spacecruft archive.
• spacecruft-classfd-missing-tle --- Outputs TLEs of classfd missing from Spacecruft archive.
• spacecruft-classfd-report --- Generate report.
• spacecruft-classfd-tle --- Outputs TLEs of classfd in Spacecruft archive.
• spacecruft-dl-ids --- Download list of IDs photographed and identified in the Spacecruft archive.
• spacecruft-ls-ids --- Lists NORAD IDs in Spacecruft archive.
• tle2git --- Convert archive of historical TLEs into git repo.

Scripts that use sattools:

• spacecruft-skymap-classfd --- Plot classfd satellites in skymap.
• spacecruft-skymap-classfd-missing --- Plot missing classfd satellites in skymap.

Run

Run thusly:

./spacecruft-classfd-all

It will store in the data directory. You can run each script, ala:

$ ./spacecruft-classfd-report
Number of satellites in Spacecruft:                8036
Number of satellites in classfd:                   217
Number of satellites in Spacecruft and classfd:    85
Number of satellites in classfd not in Spacecruft: 133

TODO

Perhaps:

• Report age of TLEs in McCants, and compare with missing, etc. Over 100 TLEs haven't had an update in 2023 (?).
• Skymap of ID'd sats versus missing ones.
• Which IDs are visible tonight?
• Groupings.
• Create TLE file of in both classfd and Spacecruft.
• Create TLE file of missing classfd from Spacecruft.
