Is the NSL-Stereo rf front end still being sold? I see GMV acquired NSL in 2020, and i don't see any rf front ends on the GMV website. Thanks!

Thank you very much for sharing, but I have a question. How can we modify the parameters to make this software receiver successfully process TEXBAT data?

Hello,

I tried collecting my own data using PocketSDR by Mr. Tomoji Takasu.
I collected for L1 and E1 signals. But when I tried processing in the program, it seems to be not working yet.
It cannot succeed any satellites in acquisition stage.
I attached here the configuration file of PocketSDR (in image file, I only use channel 1) and receiver configuration file for the program.

default_param_GalileoE1_Chapter4 - Copy.txt
default_param_GPSL1_Chapter2 - Copy.txt

Your suggestions will be helpful.
Thank you very much.

Sincerely,
Ella

I am trying to calculate delta(tau) = (I_E - I_L) ./ (2 * I_P). This is one of many traditional spoofing detection methods.

If you look at the output of FGI-GSRx, I only have one outputs of I_E & I_L while I have many outputs of I_P.

I was expecting that I_E & I_L have same number of outputs as I_P...

or

in my equation, would only I_P be the changing values and I_E & I_L remain constant?

Am I missing something?

I have tried, but the I/Q plot (discrete time scatter plot) does not look right. Did I do this correctly?

If you don't mind, could you please share your GPS param file for OAKBAT dataset?
