The Mode indicator field supplements the Status field. The Status field is set to
A for the Mode indicators A and D. The Status field is set to V for the Mode
indicator N.
For NMEA v4.0 and v4.1:
Standard Talker ID = GPS only

Four character mode indicator for each GNSS constellation
used in the position where the
•
First character is for GPS
•
Second character is for GLONASS

Third character is for Galileo
•
Fourth character is for BeiDou
N = Satellite system not used in position fix or fix not valid
P = Precise, for example no deliberate degradation such as
SA
A = Autonomous; navigation fix, no real-time fix
D = Differential; real-time position, ambiguities not fixed
R = Real-time kinematic; ambiguities fixed
F = Float real-time kinematic
xx
Number of satellites in use. For $GNGGA messages: The
combined GPS, GLONASS, Galileo and BeiDou satellites used
in the position.
