When examining the "dump" from the GPS_L1_CA_DLL_PLL_Tracking loop, I have noticed that there is an offset in the accumulated carrier phase (acc_carrier_phase_rad) compared to the carrier phase of the…

Carrier smooth pseudoranges. See Sections 2.1.5.1, 2.1.4.1.1 of MOPS. RTKLIB has function csmooth(), but it is not used.

Hi guys. I am using RTL-SDR Blog V3 to receive GPS L1 C/A signals. The receptor works well, however when I see the pseudornages values in gnss-sdr-monitor they are very extrange. A example of this va…

soundfinder_localize algorithm produces two solutions because it solves a quadratic equation. We currently choose a solution by the lower pseudorange error, or alternatively by least squares discrepan…

I am comparing the raw pseudorange values of 4 HackRF Ones and 3 Thales GG12 certified GPS receivers all connected to the same antenna. I took the average GG12 pseudorange and then subtracted all rece…

Satellites' signal can be received, but it can't calculate the pseudorange. What could be the reason?

This program is lovely.
I have discovered that the pseudoranges are not very useful unless they are adjusted with the clock offset. Should/could we correct the pseudoranges on this program so that…

I use an android device(Huawei mate 20 pro) to measure the pseudorange of the signal this projects produced. Large discontinuities appear. Why it appeared?

I am running multiple HRF1s on the same antenna and they all output different pseudoranges, by a large amount. I do have a fix when this is happening. This is extremely unsettling to me. They each hav…

Current LEOGPS basically performs pseudorange double differencing. Should eventually move towards carrier double differencing with IAR.
