GNSS is just the catch-all term. It stands for "Global Navigation Satellite System".

The Chinese system is called BeiDou.[1]

And the Russian system is named (the Russian words for) "Global Navigation Satellite System", but usually only called GLONASS because adding L, O and A is less confusing than having one name for super- and sub-sets in a single category.

The fourth global GNSS constellation is Europe's Galileo. NavIC and QZSS are regional GNSS constellations.
