The satellite orbits only go so far north? If you are far enough north for

I have several days of NMEA log files from 68 N. I think it will be simple
after I have done it, but it may be a while before I get time to plot them.
Does anybody have (non-Windows) code to that?

lack of SBAS (WAAS) is an issue.
HDOP is better, VDOP poorer because of orbit inclination (no satellites
overhead)
ionospheric effects worse (TEC varies a lot more in polar regions)
