IQ Sample data doesnt change at all

@venk - Venkatesh,

There are three gain controls used with the LimeSDR and when I used them for GNSS_SDR using Ubuntu I set them to the following settings:

PGA = 31
LNA = 15
TIA = 2

The full disclosure on how to get your LimeSDR to play on GPS is at the following link:

Running your LimeSDR on GNSS_SDR on Ubuntu 17.10

LimeSDR Users and Members, Anyone wishing to use their LimeSDR for GPS data collection and then take that data and replay it in the analysis tools for GNSS_SDR or SoftGNSS, all you need to do is the following: 1.) Install LimeSuite and all the MyriadRF drivers as you normally would from the MyriadRF instructions using the PPAs, and that follows: sudo add-apt-repository -y ppa:myriadrf/drivers sudo apt-get update sudo apt-get install limesuite liblimesuite-dev limesuite-udev limesuite-images …

I would highly recommend that you read ALL the threads on that page even if you’ve played with GNSS_SDR already. There’s a TON of information how all of us got it working with the LimeSDR and it really plays fine with it…!

Hope this helps - 73 de Marty, KN0CK
