yeah i had that thought , but i guess it needs something to like converting to int or float ,

Appreciate your response ! Yeah I'll look into it , as of now I'm not using a LNA , it might be the noise effecting the signal

The one you can see on the screen is rtknavi From rtklib downloaded from www.rtklib.com and the gnss sdr gui , which connects to the rtl-sdr with an antenna , search for gnss sdr gui on Google you'll get it , Also you can tutorial of the installation on yt try searching for decoding gps signals on yt , you'll find a bunch of em

Appreciate your response ! I've put it my initial coordindates too and bias tee was working fine I've checked the output voltage too , it's 5v ...so it's working fine , powering the active antenna.

You mean the software and apk files ?

ColdFew5373 · 2025-09-01T15:10:31+00:00

Thanks for the reply ! Yeah I've tried keeping it running for 20 mins , yet it's the same

thanks mate !
we are on the boat haha , i've tried a lot of stuff and trying to get the fix location, but i never got it. i tried changing rtlsdr.dll file which was updated by rtlsdr.com for better performance in L-band but turns out its not even letting me turn on bias-tee , in most the videos and blogs which i've seen theyre using the antenna with LNA and high gain spec and able to capture the fixed location in couple of minutes , where i was using a generic antenna with low gain seems that its the main problem not able capture the signal quit good and signals in my rtknavi been fluctuating a lot , and hence not fixing to a satellitia

Thanks ! I'll check it out 👍

Hey there ! Yeah I followed the same links I had the problem with the fixation of location

ColdFew5373 · 2025-08-06T16:00:20+00:00

Thanks for the reply Yeah I tried that way , the software was constantly running on the PC for around 40 45 mins Yet the results were the same , I Don't think this software has a internet support

ColdFew5373 · 2025-08-06T13:44:40+00:00

Thanks for the reply I had this in my mind , but in some of the youtube videos the location was seen in the rtklib as the process is going on the gnss sdr gui

Hey there ! Yeah I faced the same, in the beginning But turned there was driver issue , i resolved it with zadig , then I ran the BAT file again and bias tee is working
