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.

11 hour GPS/GNSS Simulation on a fixed point
Looking at the GitHub, I see the duration is defined by USER_MOTION_SIZE and can be specified in either dynamic or static mode. Can I get some insight on the benefits of using dynamic/static? I need to transmit a fixed GPS point, if that matters.
- My work is now requiring we share our location in order to clock in, and it prevents us from clocking in if we’re too far from work. I work from home.

iOS allows DNS request to escape the VPN tunnel
> not trivial or cheap
It sounds like your experience may have been a while ago? In 2022, it is fairly trivial and cheap: https://github.com/osqzss/gps-sdr-sim
I can not ;^) personally confirm that this works with a HackRF, which is like $300, but probably with any other reasonable tx-capable sdr.

An EFF Investigation: Mystery GPS Tracker on a Supporter’s Car
> while spoofing GPS is significantly harder
You are completely, utterly wrong. Spoofing GPS is downloading a file, and then running a commandline program with a hackrf attached.
Download and compile https://github.com/osqzss/gps-sdr-sim
Download today's ephermis https://cddis.nasa.gov/archive/gnss/data/daily/
run:
gps-sdr-sim -e $EPHERMISFILE -l $LAT,$LON,$ALT
And, if you're nearby an airport, you're violating felonies with FCC AND FAA.

Decoding captured signal of RTL-SDR by SoftGNSS
I want to simulate GPS signals by using GPS-SDR-SIM (GPS-SDR-SIM GitHub page)
unsmear
What are some alternatives?
multi-sdr-gps-sim - multi-sdr-gps-sim generates a IQ data stream on-the-fly to simulate a GPS L1 baseband signal using a SDR platform like HackRF or ADLAM-Pluto.
gnss-sdr - GNSS-SDR, an open-source software-defined GNSS receiver
SoftGNSS - UNOFFICIAL! Contains my little changes for my studies. Besides that, it is not branched from any official repo, is branched from a local PC.
