Hello dear HKUST researchers,

Firstly, I am very thankful you for sharing your various work (gnss_comm, GVINS, VINS mono and ublox driver). Each of them is very impressive and instructive for me.

I want to ask you, is there any bug in this function (UbloxMessageProcessor::sig_freq). This function returns GPS L2 frequency 1.22760E9 for Galileo E5b signal instead of 1.20714E9 if I am not wrong. Also your GVINS dataset outputs frequency as I previously mentioned. I used a workaround for processing GVINS data because it passed through ublox driver package before it saved. As I guess, GVINS algorithm also uses this signal frequency for several calculations in order for factor generation.
Thank you for your sharing your effort and knowledge to worldwide researchers.
