GNS – GNSS Fix Data
Fix data for single or combined satellite navigation systems (GNSS).
This sentence provides fix data for GPS, GLONASS, possible future
satellite systems and systems combining these.

GSA – GNSS DOP and Active Satellites
GNSS receiver operating mode, satellites used in the navigation
solution reported by the GGA or GNS sentences and DOP values. If
only GPS, GLONASS, etc. are used for the reported position solu-
tion, the talker ID is GP, GL, etc. and the DOP values pertain to the
individual system.
