Alternatives

If noaa-apt is not useful to you, these are some alternatives I found:

• WXtoImg, by far the most popular, lots of features but the site looks dead forever.

• WXtoImg Restored, unofficial mirror with installers recovered by users.

• aptdec, looks like it has real time decoding and false color.

• xwxapt, receives and decodes live, something like WXtoImg. I should try it sometime.

• SatNOGS, it is a big project that also happens to include a APT decoder.

• atp-dec/apt-dec, works really good. Keep in mind that the 1.7 release looks newer than the repo’s master branch. I tried several times to compile the repo’s master branch without success, later I realized that there was a newer 1.7 release and it worked.

• pietern/apt137, written in C, extremely fast.

• zacstewart/apt-decoder, written in Python, slower than the others but really simple. I wrote the syncing algorithm.

• Alexander-Barth/APTDecoder.jl, written in Julia. Never tested it but has map overlay.

• ThatcherC/APT3000, written in JavaScript, looks very fast.

• rsj56/apitran, fork of zacstewart/apt-decoder with some extra automation.

Others I found on GitHub:

• brainwagon/noaa-apt, written in C, does not sync images.

• LongHairedHacker/apt-decoder, written in Rust.

• dlew1716/APT, written in Python and C++, not easily usable.

• toastedcornflakes/APT, written in Python, not easily usable.

• la1k/wxfetch, fork of atp-dec/apt-dec, I never tried it.

• SopaXorzTaker/napt, written in C, can’t figure out how to use it.

I measured the speed of most of them using the time utility from bash, and made a comparison of the results on ./extra/comparison.ods.
