Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

- ELI5: If there are many satellites orbiting earth, how do space launches not bump into any of them?
-
Orbit and footprint viz
I didn't watch the video but Gpredict has tracking and a map showing the orbit path and ground footprint for satellites you select.

My homemade QFH antenna, with some images I’ve captured from NOAA and Meteor satellites.
I'm using sdrpp with Doppler correction with gPredict. I record the signal in sdrpp and then process it with noaa-apt.

Interfacing a go-to mount with the Orbitron software.
Your missing the point basically they mean upgrade your software to Gpredict satellite tracking software (GPL) which has Linux and Windoze versions. http://gpredict.oz9aec.net/ Gpredict uses hamlib to control both radios and mounts. Hamlib supports many radios and mount support includes Meade, Celestron and iOptron IEQ45 alt-az mounts via AUSCOM standard software. Once done the next part is ensuring you set up you com ports to appropriately control your devices radio and mount and making sure the appropriate devices are set-up in the software. Note if your com ports change say because you replug something, don't forget to update the port details otherwise coms will fail and the relevant device won't be usable. Check out the documentation and there are a number number of set-up videos on YouTube if needed.

FOSS for Amateur Radio
LWN usually has great content but they've missed out on so much free ham software in this article that I use regularly.
My main HF rig is an older Yaesu FT-950. I tapped the IF and brought it out of the chassis where it is plugged into a cheap RTLSDR. I then access that RTLSDR (with free drivers) with GQRX (free software for visualizing anything compatible with SoapySDR or GNU radio), and the result is that I get a panadapter that is arguably better than what's available on $2000 radios.

As for VHF/UHF stuff, I would be hopeless if it wasn't for GPredict on my laptop making it simple to track LEO satellites. https://github.com/csete/gpredict Short video here: https://photos.app.goo.gl/eg87BWpt2XnJdGFp7
I also run an APRS igate, which is powered by direwolf: https://sielicki.github.io/posts/radio-scanner-aprs-igate/ , https://github.com/wb2osz/direwolf

Making Sense of Satellite Data, Open Source Workflow
It hasn't been updated in a couple years now, but `gpredict` is a nice desktop program that will show projections of satellite orbits and predict upcoming passes.

Receiving Weather Satellite Images Using SatDump
GOES sats are geostationary but the NOAA APT satellites are encircling the planet and you can pick them up. Old tutorial but still relevant, just use "noaa-apt" tool[0] instead of WXtoImg. https://www.rtl-sdr.com/rtl-sdr-tutorial-receiving-noaa-weat...

- Hi 2
- SDR# and NOAA Satellites
- Made a very simple 137 MHz dipole V antenna, made out of copper brazing rods and a terminal block and this is the first picture of NOAA 18 I got from it, also it picks up 250 MHz Satcom pirate transmissions rather well. Much better than my pa0rdt antenna which adds a bunch of noise!
-
Why the image is so small?
Sometimes WXtoIMG just discards parts of the recoding when the signal wasn't strong enough. In those cases I've had some luck running the recorded .wav file through noaa-apt to get the full image.
-
Images pulled with RTL-SDR antenna NOAA
so the NOAA_APT decoder link on your guide did not work properly, By chance did you mean this link https://noaa-apt.mbernardi.com.ar/?
-
At least as long as they're not using the dev container...
So far I only use it for noaa-apt program though.
-
WXtoImg not decoding images
Had this exact problem, the thing that I found is that GQRX records at the wrong sample rate, which WXtoImg can’t handle. However, https://noaa-apt.mbernardi.com.ar this utility did work for me. I’ll also note that WFM is the setting I use in GQRX, not AM
-
Does anyone know whats happening here?
You should try noaa-apt too, it usually gives better results for me.
