# classfd cruft

DRAFT DRAFT DRAFT

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
```


# 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-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.

# 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
```


# Spacecruft

# 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.
