Not so different for NTPsec, but it is for gpsd. Those other sat
flavors mean the NMEA gets tortured to support them. Exposing many
'opporunities' to improve gpsd.

You would likely not see BeiDou on the east coast. I see a few of those
birds on occasion.
I've been told the timekeeping on the GLONASS is sub-par. Some even suggest
turning off GLONASS for better accuracy. Would be interestnig to find out.
In Central Oregon we get GPS outages due to testing in Nevada. So the
different wavelength of GLONASS is a plus.
