Re: [Discuss-gnuradio] samp_rate in GNU Radio

Dear Priyanka,


The maximum sample rate is 3.2 MS/s (mega samples per second). However, the RTL-SDR is unstable at this rate and may drop samples. The maximum sample rate that does not drop samples is 2.4 MS/s, however some people have had luck with 2.8MS/s and 3.2 MS/s working well on some USB 3.0 ports.

Thus, something between 2.0 and 2.4 MS/s would work for you.

Maybe this paper could be of your interest, although it is a little bit outdated: 


Hope this helps,
Carles

Hi,

I am trying to receive GPS signal using RTL-SDR with GNU Radio. I am interested in L1 band of GPS signal (1575.42MHz). But I am confused about my sampling frequency. What value should I choose as samp_rate in RTL-SDR block of gnuradio? 

Thank you
Priyanka
