Greetings! I would be very interested to contribute to GNSS SDR for this year's GSoC. After studying the proposed topics and the proposal submission process, I would like to ask: - Are the contributors selected only through the proposals submitted to the GSoC website or is there an additional evaluation as well (e.g. through preliminary tasks) - Are there any ways to contribute in advance in order to gain a better grasp of the project? Is there an issue/bugfix list for new contributors? Thank you in advance! Kind regards, Georgios Kikas Department of Electrical and Computer Engineering Aristotle University of Thessaloniki, Greece |

I am not sure if this can help you, but when I started adding custom functionalities to gnss-sdr (spoofing detection & spoofing/jamming cancellation) I was also challenged by the complexity of the software architecture so I document a basic block addition at [ https://github.com/oscimp/gnss-sdr-custom | https://github.com/oscimp/gnss-sdr-custom ] which has not been updated for the last three years but should not be completely irrelevant still. Best, JM De: "Rodrigo Trindade" <rod...@gm...> À: "gnss-sdr-developers" <gns...@li...> Envoyé: Lundi 3 Juillet 2023 23:08:27 Objet: [Gnss-sdr-developers] Usage of GNU Radio blocks Good evening! I have been working on an implementation for the acquisition block, and when I tried to run tests to check the functionality of the block, I noticed that there are some block implementations in GNU Radio. However, I didn't understand how to insert these blocks. I would like to know if you have a tutorial for that or an example in GNU Radio of a functioning positioning chain.If you could provide me with some of this information, I would be very grateful. _______________________________________________ GNSS-SDR-developers mailing list GNS...@li... https://lists.sourceforge.net/lists/listinfo/gnss-sdr-developers |

Vipin, Can I suggest that your first step is to read https://github.com/gnss-sdr/gnss-sdr/blob/main/CONTRIBUTING.md Then, pick an existing issue to work, and submit a pull request. I can suggest https://github.com/gnss-sdr/gnss-sdr/issues/565 is a relatively straightforward one for you to code and test. Given that this code base is C++, your language skills may be insufficient. But see what you think. --- Jim Melton From: Vipin Kumar <vip...@gm...> Sent: Monday, November 21, 2022 02:33 To: gns...@li...

Dear Karin, on Ubunto 20.04, "sudo apt-get update && sudo apt-get install gnss-sdr" should install version v0.0.11, which is quite old and buggy. I recommend building the software from source or using the Docker images. The list of dependencies for Ubuntu 20.04 is: sudo apt-get install -y --no-install-recommends build-essential cmake git ca-certificates libboost-dev libboost-date-time-dev libboost-system-dev libboost-filesystem-dev libboost-thread-dev libboost-chrono-dev libboost-serialization-dev liblog4cpp5-dev gnuradio-dev gr-osmosdr libpugixml-dev libpcap-dev libblas-dev liblapack-dev libarmadillo-dev libgflags-dev libgoogle-glog-dev libgnutls-openssl-dev python3-mako libmatio-dev libgtest-dev libprotobuf-dev protobuf-compiler gr-limesdr Hope this helps, Carles On Mon, Sep 12, 2022 at 11:22 AM Karin DASSAS <kar...@un...> wrote: > Hello, > > I would like to install GNSS-SDR on my system (in order to process L5 > band, airborn campaign), but I received the message "no package found" > using sudo apt-get gnss-sdr. > > Is there another repository with the package gnss-sdr for this version > of Ubuntu or should I build everything from source ? > > Or maybe do you advise to use the docker image ? > > Best, > > Karin > > > > _______________________________________________ > GNSS-SDR-developers mailing list > GNS...@li... > https://lists.sourceforge.net/lists/listinfo/gnss-sdr-developers > |

Hello, I would like to install GNSS-SDR on my system (in order to process L5 band, airborn campaign), but I received the message "no package found" using sudo apt-get gnss-sdr. Is there another repository with the package gnss-sdr for this version of Ubuntu or should I build everything from source ? Or maybe do you advise to use the docker image ? Best, Karin |

Hello list! I have been around the GNU Radio community for a few years, but relatively new to GNSS-SDR. I am trying to get a basic setup running in real-time with an RTL-SDR v3 A few questions/observations: - Given the RTL-SDR v3 is supposed to ship with a 1ppm oscillator, can I skip any calibration steps and just set internal_fs_sps, and input filter config to the nominal frequencies (2e6 for sampling freq 0 hz for IF deviation)? - I notice if i set threshold to some value below 0, the application moves to tracking on all channels immediately on start-up. Then it loses lock on all channels and re-acquires/moves to tracking to the same satellites on all channels. If i set the threshold to some arbitrarily high value (like 10.0) the false acquisitions stop. I may not fully understand what the threshold should to. - I've attached the config file if anyone might be kind enough to take a quick look for gross errors. -John |

Hello, I am tryig to get started with my RTL-SDR v3 and GNSS-SDRLIB. I want to test some GPS signals. I am basically following this tutorial here https://www.rtl-sdr.com/rtl-sdr-tutorial-gps-decoding-plotting/ And other than changing the -d 0 to -d 1 this seems to work: C:\Users\AlGrant\Downloads\bt_driver>rtl_biast.exe -d 1 -b 1 Found Rafael Micro R820T tuner C:\Users\AlGrant\Downloads\bt_driver> Then however starting GNSS-SDRLIB seems to fail with the monitor window showing: GNSS-SDRLIB start! error: failed to open rtlsdr device #0 error: rcvinit Can someone help me to please progress? Thank you, -- "Beat it punk!" - Clint Eastwood |

Hi, thanks for the response. We have not generated spoofing signals yet. Firstly, we are trying to collect the original GNSS signals by using active antenna and USRP. Also, we are using GNSS-SDR (not GPS SDR SIM). We will try with 2.5 MHz sampling frequency and 16 bit quantization. Regarding printed "D" and adjusting buffers, we made all the steps from the link<https://kb.ettus.com/USRP_Host_Performance_Tuning_Tips_and_Tricks#Thread_Priority_Scheduling> and nothing worked in our case. Maybe we missed something or maybe the problem could be with computer e.g. processor?

I my case I was using an Active antenna for the transmission of the signal and noticed that I was jamming the whole spectrum instead of spoofing. [X] imt...@gm...

Firstly, we followed all steps from GNSS-SDR configuration page and we successfully got the position fixes with downloaded file of raw signal samples as at the link<https://gnss-sdr.org/my-first-fix/>. Afterwards, we tried to get the position fixes with active GNSS antenna but unsuccessfully. We set all the parameters as at the instructions at the link<https://gnss-sdr.org/conf/> and ran 'my_GPS_receiver.conf' file. As the result, we got printed 'D' (please see screenshots 1 and 2 attached). We tried to solve this problem by following the instructions at ETTUS page<https://kb.ettus.com/USRP_Host_Performance_Tuning_Tips_and_Tricks#Thread_Priority_Scheduling> but nothing worked in our case. Then, we tried to set the sampling frequency to 2MHz and there was no printed 'D' after running the conf file. However, we didn't get the position fixes and we only got 'Loss of lock in channel' (screenshot 3). We searched for the solution and we wonder if missed something or we do not have all necessary equipment (we saw that bias-tee is needed for some daughterboards). We would be thankful if you could help us with our problem. Thank you in advance and best regards, Katarina Radoš and Marta Brkić |

We have not generated spoofing signals yet. Firstly, we are trying to collect the original GNSS signals by using active antenna and USRP.</div>

Regarding printed "D" and adjusting buffers, we made all the steps from the <a href="https://kb.ettus.com/USRP_Host_Performance_Tuning_Tips_and_Tricks#Thread_Priority_Scheduling" title="https://kb.ettus.com/USRP_Host_Performance_Tuning_Tips_and_Tricks#Thread_Priority_Scheduling">

<div>
<div dir="ltr">how are you generating the spoofing signals? <br>
</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">the sampling frequency of the N210 is 2.5 MHz. if you are using GPS SDR SIM its default sampling frequency is 2.6 MHz. also you will need to generate a 16 bit sample for the USRP.
<br>
</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">for better results make sure you've a GPSDO installed and you are using active antenna for receiving the signal only. I my case I was using an Active antenna for the transmission of the signal and noticed that I was jamming the whole spectrum
instead of spoofing. <br>

</div>
<div class="x_x_elementToProof" style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
Firstly, we followed all steps from GNSS-SDR configuration page and we successfully got the position fixes with downloaded file of raw signal samples as at the
<a href="https://gnss-sdr.org/my-first-fix/" title="https://gnss-sdr.org/my-first-fix/">
link</a>.</div>
<div class="x_x_elementToProof" style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
Afterwards, we tried to get the position fixes with active GNSS antenna but unsuccessfully. We set all the parameters as at the instructions at the
<a href="https://gnss-sdr.org/conf/" title="https://gnss-sdr.org/conf/">link</a> and ran 'my_GPS_receiver.conf' file. As the result, we got printed 'D' (please see screenshots 1 and 2 attached). We tried to solve this problem by following the instructions at
<a href="https://kb.ettus.com/USRP_Host_Performance_Tuning_Tips_and_Tricks#Thread_Priority_Scheduling" title="https://kb.ettus.com/USRP_Host_Performance_Tuning_Tips_and_Tricks#Thread_Priority_Scheduling">
ETTUS page</a> but nothing worked in our case.</div>

</div>
<div class="x_x_elementToProof" style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
Then, we tried to set the sampling frequency to 2MHz and there was no printed 'D' after running the conf file. However, we didn't get the position fixes and we only got 'Loss of lock in channel' (screenshot 3). We searched for the solution and we wonder if
missed something or we do not have all necessary equipment (we saw that bias-tee is needed for some daughterboards).</div>

<div dir="ltr">the Ddddddd clearly indicated a data overflow. if you get U it means underflow. you will need to adjust the buffer accordingly. use 2.5 MHz sampling frequency and 16 bit quantization <br>

<span style="color: rgb(0, 0, 0); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt;">we have problem with collecting GNSS signals for GNSS spoofing by using USRP N210 (daughterboard UBX-40), active GNSS antenna (</span><a href="https://www.scribd.com/document/511736732/Datasheet-2-Antena-Gps-Gpsglonass-36-n-Ga" title="https://www.scribd.com/document/511736732/Datasheet-2-Antena-Gps-Gpsglonass-36-n-Ga" style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt;">GPSGlonass-36-N-GA</a><span style="color: rgb(0, 0, 0); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt;">)
and GNSS-SDR. </span><br>
</div>
<div class="x_elementToProof" style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
Firstly, we followed all steps from GNSS-SDR configuration page and we successfully got the position fixes with downloaded file of raw signal samples as at the
<a href="https://gnss-sdr.org/my-first-fix/" title="https://gnss-sdr.org/my-first-fix/">
link</a>.</div>
<div class="x_elementToProof" style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
Afterwards, we tried to get the position fixes with active GNSS antenna but unsuccessfully. We set all the parameters as at the instructions at the
<a href="https://gnss-sdr.org/conf/" title="https://gnss-sdr.org/conf/">
link</a> and ran 'my_GPS_receiver.conf' file. As the result, we got printed 'D' (please see screenshots 1 and 2 attached). We tried to solve this problem by following the instructions at
<a href="https://kb.ettus.com/USRP_Host_Performance_Tuning_Tips_and_Tricks#Thread_Priority_Scheduling" title="https://kb.ettus.com/USRP_Host_Performance_Tuning_Tips_and_Tricks#Thread_Priority_Scheduling">
ETTUS page</a> but nothing worked in our case.</div>

<br>
</div>
<div class="x_elementToProof" style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
Then, we tried to set the sampling frequency to 2MHz and there was no printed 'D' after running the conf file. However, we didn't get the position fixes and we only got 'Loss of lock in channel' (screenshot 3). We searched for the solution and we wonder if
missed something or we do not have all necessary equipment (we saw that bias-tee is needed for some daughterboards).</div>

<div dir="ltr">how are you generating the spoofing signals? <br>
</div><div dir="ltr"><br>
</div><div dir="ltr">the sampling frequency of the N210 is 2.5 MHz. if you are using GPS SDR SIM its default sampling frequency is 2.6 MHz. also you will need to generate a 16 bit sample for the USRP. <br>
</div><div dir="ltr"><br>
</div><div dir="ltr">for better results make sure you've a GPSDO installed and you are using active antenna for receiving the signal only. I my case I was using an Active antenna for the transmission of the signal and noticed that I was jamming the whole spectrum instead of spoofing. <br>

Hi, we have problem with collecting GNSS signals for GNSS spoofing by using USRP N210 (daughterboard UBX-40), active GNSS antenna (GPSGlonass-36-N-GA<https://www.scribd.com/document/511736732/Datasheet-2-Antena-Gps-Gpsglonass-36-n-Ga>) and GNSS-SDR. Firstly, we followed all steps from GNSS-SDR configuration page and we successfully got the position fixes with downloaded file of raw signal samples as at the link<https://gnss-sdr.org/my-first-fix/>. Afterwards, we tried to get the position fixes with active GNSS antenna but unsuccessfully. We set all the parameters as at the instructions at the link<https://gnss-sdr.org/conf/> and ran 'my_GPS_receiver.conf' file.

I'm not using pluto for gnss-sdr - I'm using the pluto for other things. I'm only indicating if you're using gnuradio-3.10 you don't need to install anything to use pluto except libad9361-dev. The code need for pluto is in libad9361-dev - gr-iio is included in the release of gnuradio 3.10. That is, gr-iio is no longer an OOT module. If you have the source code for gnuradio-3.10 then the code for gr-iio is in a subdirectory of gnuradio-3.10. -- CInaed On 7/11/22 13:19, Will Silberman wrote: > Thank you Cinaed!
