Also, if we use GPS to refer to GLONASS, why don't we use GPS to refer
to LORAN and inertial systems?

The other terminology problem is people referring to a "GPS receiver"
(which is really one member of the set known as the "user segment") as
"a GPS".   It seems the project has used the term GPSr for that, which
is both compact, not really confusing for those who don't understand,
and a non-offensive abbreviation for those who do.
