We will check and recapture signals if needed. But I can not test samples for IRNSS. Is there any open source IRNSS software receiver?

We are also working on 16 bit capturing but do not have a hardware jet.

Also about Beidou. I can not test samples for Beidou. Is there any open source Beidou software receiver?

Hello, vasub.
Which files exactly are you talking about? I will check.

The GPS L1, L2 and and GLONASS L2 file which is uploaded at https://drive.google.com/drive/folders/ ... R4c1BUVEE..
I could not find valid preamble in GPS L1 L2 and Glonass L2 file only GLONASS L1 is working fine...
Please check and also can you please upload IRNSS file and GPS I16 (IQ 16 bit) file for GPS or GLONASS.
Thank you


Hello!
I've updated signals in a folder: https://drive.google.com/drive/folders/0B_KNV6Fq4B_dZjBSelR4c1BUVEE

There are three files (dumped not in a time): GPS L1, GLONASS L1 and L2.
Also I put a little software to check signals.
Best regards,

Viktor

There is not software known to me for IRNSS which is freely available.. I am trying to develop my own in MATLAB and Labview.. I already developed MATLAB code for GLONASS L1, L2 and GPS L1/L2 for IQ16 bit.. I am also using USRP 2932 to record GLONASS GPS and IRNSS in IQ16 and IQ8 both..
However the required amplifiers and signal splitters are not availble in India and I need to import them from US.. This is expensive and that is why my test is getting delayed.. Let me know if I can do something for you.. Thanks a lot for your support and help
