I rarely post comments but I just want to write that I really enjoy your channel, the topics nearly always 'click' with me making me go off and find out how it works. Well done, please keep doing it.

I cannot figure out HOW it took me this long to find this OUTSTANDING channel. Seriously, I stumped.

Impressive! I really don't know the limits of RTL-SDR.. amazing! Please make next video on IMSI Catchers... That ll be interesting 👍

[olivierconet]

Really incredible!
I'm Always fascinated how it is now possible to do that sort of things, when some time ago everybody would have said: oh no, too complicated, let it to professionnals (and I am an engineer)
Bye the way, too many srupid ads, thanks to Google

Another great video. I always keep a V3 around for this. Always looking for new ideas for SDR.

Love the satellite and gps videos! Your explanations are great

[acestudioscouk-Ace-GACE]

A complex subject very well explained. Thank-you.

Interesting video as always but the advertising like the rest of YouTube is ruining it. Do you upload to any other platforms? YouTube is really pissing me off with advertising every few minutes.

You probably need to enter a Google Maps API key to get that to work. You should be able to get a free key from Google, but last time I did this I remember it was quite complicated.

[ronylanssiers]

Very much appreciated that you made this video!

Hello, Techminds. I am currently using the same hardware and software setup on Windows to log the GPS I/Q data. However, I'm encountering an issue. When I press "Start" in the GNSS SDR-LIB GUI, it doesn't seem to initiate any process. Additionally, RTK-Navi is stuck showing the "connecting" status.

I would appreciate any guidance you can provide to help me resolve this problem. Thank you.

Looking like it has duel frequency capability see front end One and a option for a second front end capability very nice Now all you need I guess is a multi band antenna 📡 probably won't work as well as a dedicated device or Ublox kit but it seems like a very affordable alternative 😀 Nice video 👏.

The gnuplots after pressing start in gnss do not pop up but the cmd windows show up. The monitor in gnss does show a similar feed as in the video. RTKplot also experiences timeout while trying to connect to localhost. I'm not too sure what's the problem, I followed the video step-by-step. Any advice?

Is it possible to see the signal strenght of the GPS like to quantify the signal level with a SDR?

[antenadx]

Please in the next video show how to decode mobile network signals

I get data scrolling in the monitor window of GNSS even when no antenna is connected. With an antenna connected and RTK running, nothing is displayed. Admittedly, I don't have a proper GPS antenna, just a dipole I use for ADSB, so I guess it could just be down to s/n ratio.
Thanks!

If you install the ucentre software from ublox you should be able to link this to the nmea output stream to provide a full gps decode

Can you use hackrf instead of rtl sdr?? Should we change something in the settings for the hackrf ??

Dear all,
I am unable to get a GPS fix with RTKNAVI.
I am using Win 10, the RTL SDR V3 dongle(RTL2832U R860 TCXO+BIAS T+HF), bias tee on, GPS antenna and RTKLIB 2.4.3.
Is it working for anyone? Could you kindly tell me how you managed it?
I am not the only one having problems. Thank you for your attention.

I read an article last week about capturing data that's travelling over satellite internet connections, like from users on planes. Interesting to see how easy/hard that would be to do
