Did you know Ap5 or AU20

Using winXP huh?

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.

What 3D point algorithm did you use?

is this underground?

Is it using IR or ultrasound? Can i get a link with the sensors it is using? Thank you

Speaking of the base station error. Does distance between a smartphone's location and the base station matters ?

If I understood it correctly this solution processes the whole dataset, and can not be used on the go?

The results are truly amazing. I've spent months to understand basic linear KF, so that I could improve process Android locations (not NMEA sentences, but already processed stuff provided by the Fused Location Provider which is part of Android API), but results were even worth than the original data.

Amazing!

I would love to learn how do you determine the visibility of satellites on the camera

Wow

Also how can you see satellites

Dear Taroz Sensei is it a simple sky plot plotted over a video?

hi taroz, when I start the GNSS SDR LIB, the DOS windows continously start opening and it doesn't close at all. also when it try the rtknavi from rtklib, it says local host time out

Whoa nice, what is the max update rate?

Hi, Mr. taroz, I'm trying your GNSS-SDRLIB with the BladeRF x40. I tried the driver versions from BladeRF 1.0 ~ 1.5. Everything, Hardware & software setting looks ok, but it doesn't work well. I can't see the results you showed above. Can you give me some of suggestions about the BladeRF installation or parameter settings for runing GNSS-SDRLIB. Thanks!

Какой тип антенны Вы использовали?

Where can we buy these in Canada

is it expensive ? It could be combined with the SLAM

Very impressive! :D

How is this going?

Please speak!!

That's so cool

I have a question, have gnss small size for localization workers in construction? And prices accessible?

ono word. wow

I would like to buy bladeRF GPS generator premade solution where would i stgart? anyone want to sell theirs?

hi bro PM me

What type of antenna is needed to transmit the GPS signal?

Hi do you think you could add HackRF Support?

Hi, how can you receive real time signal by bladeRF?

Will it also decode the time signal all gps broadcast?

Poor reception. I tried it outside with a properly tuned antenna and it was super accurate.

I don't understand, i though that with RTK you could get a very good precision in the order of cm...

What an excellent program! I have your GNSS-SDRLIB up and running, with several satellites showing in the windows. What I am unclear on is how to set up the output of your program so it properly feeds into RTKLIB. Do you have instructions or a listing of the proper settings? Thanks.....CdP

Hi. I got last GNSS-SDRLIB from github and connected a active antenna via bias tee to a bladerf. When I pressed start, no any windows popuped (like your g22, g23 ...). How to run gnss-sdrlib? Please make video with spectrum of gps signal in any program like gqrx or sdrradiov2. Thanks

Would this be usable connected to a linux machine? Like a Raspberry Pi? Thank you in advance

Hi mate, I want to know what you have connected to the other end of the Blade RF. And i tried using the latest software wherein the cmd windows came and went but i didn't receive any plots. Please help.

are you study in Tokyo University of Marine Science and Technology?

Hi Taro. When I connect the BladeRf and press "start", i get a monitor error :"error: failed to open baldeRf : Operation timedout". Is there anything need to be done with the Bladerf to make it work?

does it support usrp ?

Hello Taroz. How do I get the BladeRf option in the Input Type menu? Is it happen automatic when I connect the BladeRf to the PC?

I used an active GPS antenna (such as www.sparkfun.com/products/8254). But you need to supply DC 3.3V to the antenna in some way. I modified the DVB-T dongle.

great ! how you do it ?? :)

nice job, well done !

good work, could you tell which antenna , you have used and how you have connected , via LNA, bias T

Fascinating visualization!
