GGA (GPS Position) Message
$PASHS,NME,GGA,X,Y
This command enables/disables the NMEA GPS position response message on port x,
where x is either A, B, or C, and Y is ON or OFF. This message is not output unless
position is computed.
Example: Enable GGA on port A
$PASHS,NME,GGA,A,ON followed by output command
$PASHS,OUT,x,NMEA where x is the output port.
$GPGGA
The response message is in the form:
$GPGGA,hhmmss.ss,ddmm.mmmmm,s,dddmm.mmmmm,s,n,
qq,pp.p, saaaaa.aa,u,±xxxx.x, M,sss,aaaa *cc
where the structure is as defined in Table 4.44.

Field Description
1 Current UTC time, hhmmss, of position fix in hours, minutes and seconds.
2 Latitude component of position, ddmm.mmmmm, in degrees, minutes and fraction of minutes.
3 atitude sector, s = N - North, s = S - South.
4 Longitude component of position, dddmm.mmmmm, in degrees, minutes and fraction of minutes.
5 Longitude sector, s = E - East, s = W - West.
6 Raw/differential position, n n = 1 - Raw; position is not differentially corrected n = 2 - position is
differentially corrected.
7 qq = number of SVs used in position computation.
8 HDOP - horizontal dilution of precision, pp.p = 00.0 to 99.9.
9 GPS Sensor-computed altitude, saaaaa s = "+" or "-" aaaaa = Altitude 00000 to 30000 meters
above WGS-84 reference ellipsoid. For 2-D position computation this item contains the altitude used
to compute the position computation.
10 Altitude units, u = M - meters.
11 Geoidal separation (value output only if Geoidal Height option (G) is installed in the receiver).
12 Geoidal separation units, u = M - meters.
13 Age of the differential corrections, sss, in seconds.
14 Base STID, aaaa.
