     3.03           N: GNSS NAV DATA    M: MIXED            RINEX VERSION / TYPE

GPSB   1.1059E+05 -3.2768E+04 -2.6214E+05  1.9661E+05       IONOSPHERIC CORR

For a nav data file like above the RINEX_get_nav.m reads the wrong iono values. Reading for iono values must be stopped once data has been obtained at line 71.

Could work:

iono_loaded = false;
while (isempty(header_end))
    .
    .
    %if the ionosphere parameters label was found
    if (iono_found && ~iono_loaded)
        .
        .
        iono_loaded = true;
    end
    header_end = strfind(lin,'END OF HEADER');
end

I applied your suggested fix here: https://sourceforge.net/p/gogps/code/1044/
I would appreciate if you could check if it works properly with your RINEX files.
Thank you very much!
