Thanks Marcus & Philip.
Marcus - I will try what you suggested and let you know the results. I am
working on another couple of projects one of which initiated this upgrade.
That project is working ok but I noticed 2 of my previous projects have the
OOT issue. I thought maybe there might be a quick fix for the older
projects - but of course not. Almost nothing is quick and easy.
Thanks again for the help,
Jim

Subject: Re: Problem with 3.10.12.0
Hey, Jim,
something, *anything*, really, in /usr/local!
If that's not empty, there's stuff in there that you've installed manually
(not via apt);
which is totally OK, but everything in there doesn't get updated by apt,
which means you
need to keep tabs on what you've installed there, and remove it yourself,
build it anew,
when one of its dependencies gets updated via apt.
What Philip is saying here is that this is a common occurrence: user needs a
specific
version of something that their Linux distro doesn't package, installs it
manually into
/usr/local, then the system is upgraded, but /usr/local contains things
founded in the
state of the system prior to the update.
Valuing your time as high as I do mine, I'd do this: go and move
*everything* in
/usr/local out of the way
(e.g. `sudo mkdir /usr/local-old && sudo mv /usr/local/* /usr/local-old/`),
then make sure
you're working from empty build/ directories, build and install the
out-of-tree modules
you need anew (and any other software you need from your old /usr/local).
Best regards,
Marcus

Re: Problem with 3.10.12.0
Hi Jim,
it still looks like there's a pybind around that is built against Python 3.11. Where that
comes from, or where specifically it is on your system: I don't know more than that, I'm
afraid.

Re: Problem with 3.10.12.0
Marcus,
I upgraded to GNU Radio 3.10.12.0.
Python 3.13.5 came along with it.
I am using Debian 13 (Trixie) on my RPi.
I used sudo apt install.
I hope this is enough info to help.
Jim

Hey Jim,
don't know how you've installed Pybind and your Python! As said, it looks
like your update
of Python happened without the other libraries, and here, Pybind, getting
rebuilt/updated
as well. I don't know your operating systems and installation methods, so
it's impossible
for me to advise!

I upgraded to GNU Radio 3.10.12.0.
Python 3.13.5 came along with it.
I am using Debian 13 (Trixie) on my RPi.
I used sudo apt install.
I hope this is enough info to help.
Jim

Hey Jim,
don't know how you've installed Pybind and your Python! As said, it looks
like your update
of Python happened without the other libraries, and here, Pybind, getting
rebuilt/updated
as well. I don't know your operating systems and installation methods, so
it's impossible
for me to advise!
Best,
Marcus

Re:Self-proposed idea: BeiDou B1C Signal Simulator OOT Module
Subject: Re: [GSoC 2026] Self-proposed idea: BeiDou B1C Signal Simulator OOT Module
Hello Sir,
The constellation simulator direction makes much more sense. If the output can actually give a software receiver enough to compute a real PVT fix, that's something genuinely useful for researchers, students, anyone.
So here's how I'm thinking about the expanded scope now
- multi-constellation , with Doppler shifts and time-of-flight delays that match what a receiver at a given location and time would actually see
- Generate proper navigation messages so a receiver can extract ephemeris and compute a position fix
- Validate everything using GNSS-SDR as a software receiver feed the generated I/Q straight in and check if it produces a valid PVT solution. No hardware needed.
One thing I'm unsure about: is it better to do BeiDou B1C really well and completely, or to cover B1C + GPS L1C + Galileo E1 at a slightly shallower level? Since all three share 1575.42 MHz I can see the appeal of multi-constellation.Would love your take on this.
I'll start working on a proper week-by-week draft and share it here soon for feedback.
Best,
Devanshi.

Hi Devanshi,
Thanks for sharing this idea. Here is some quick feedback.
You don't say explicitly, but my understanding from what you wrote is
that your idea is to generate a single B1C signal with nominal chip rate
and no Doppler. This does not seem enough work even for a small (90
hour) project, specially if you are already strongly familiar with GNSS
signal generation and the B1C signal. Such kind of simulator is of
fairly limited use, since it only allows to test that a receiver is
capable of acquiring and tracking a single signal in these conditions.
It is more common to have constellation simulators, which are capable of
simulating signals from multiple satellites whose times of flight and
Dopplers are consistent with the signals that a receiver in a given
location would see. A constellation simulator, if well planned out,
might be reasonable for a GSoC project (probably more on the larger side
of the project size spectrum). Constellation simulators can be used to
obtain a PVT solution with a receiver, and test it in reasonably
realistic conditions.
You should detail in your proposal how you plan to test this. It is fine
that the tool itself generates baseband IQ and does not require any
hardware, but you will need to test somehow that the signals you are
generating are correct. Ideally you would use a hardware receiver and an
SDR to transmit your baseband IQ, but this requires you to already have
this hardware. If you don't have the required hardware, using a software
receiver is a good alternative, but you will need to identify such a
software receiver that allows you to check all you generate.
Another way in which you could increase the scope of your proposal and
make it more attractive is by including open service signals from other
constellations (GPS, Galileo, etc.), all of which have ICDs which are
publicly accessible.
Best,
Daniel.
