NMEA GNS Sentence
The NMEA GNS sentence contains time and position fix related data for a single or combined
satellite navigation system. Separate $GPGNS and $GLGNS sentences are used to report data
calculated from individual systems if a combined GPS+GLONASS position is output. A single string
will be output if no GLONASS data is in use.
Structure and Example:
$GPGNS,hhmmss.ss,ddmm.mmmmmmm,a,dddmm.mmmmmmm,b,Q,ss,p.p,h.h,g.g,l.l,nnnn*cc<CR><LF>
$GNGNS,104601.00,5707.7332018,N,00204.7778500,W,DD,12,0.71,24.743,50.284,,*45
$GPGNS,104601.00,,,,,,09,,,,3.0,0001*44
$GLGNS,104601.00,,,,,,03,,,,3.4,0001*56
GNS sentence defined:
GNS = GNSS Fix Data
hhmmss.ss
UTC of position
ddmm.mmmmmmm
latitude of position
a
N or S, latitude hemisphere
dddmm.mmmmmmm
longitude of position
b
E or W, longitude hemisphere
Q
Mode Indicator. First character is for the GPS system, the second character
for the GLONASS system. (N = No Fix, A = Autonomous, D = Differential, P =
Precise, R = Real Time Kinematic, F = Float RTK, E = Estimated, M = Manual
Input Mode, S = Simulation Mode)
ss
number of satellites in use
p.p
horizontal dilution of precision
h.h
antenna altitude above mean-sea-level
g.g
Geoidal height
l.l
age of differential GPS data
nnnn
Differential reference station ID, 0000 to 1023
*cc<CR><LF>
checksum, carriage return and line feed
