I have already constructed a GPS signal but when I read it through GNSS SDR it says the preamble is invalid which means my subframe data needs reworking.
Can you please tell me if it is possible to use this code along with RINEX files to generate real satellite signal?
Hello, nice job. I have a question how do you estimate and correct the doppler effect?
Dear team,
thanks for giving nice reference design, I have gone through the code its very resourceful.
As I am little new for GNSS generation, I have doubt that how to use this design with Navigational msg (RINEX file or NMEA) for getting modulated GNSS signals.
I have an issued with FREQ_DOPP resolution for L5+ case. If you change number of bins (in linespace) you are getting peaks at different frequencies. If you change from 31 to 51 bins peak moves to different frequency, this is not expected.
I can't find where error is.
