Pos: Position Message - ashtech DG16 Reference Manual

POS: Position Message

$PASHS,NME,POS,x,c,[f]
Enable or disable NMEA position response message on output port x, c is ON or
OFF, and f is the optional message output rate ranging from 0.05 to 999 seconds
depending on the measurement update rate option installed.
The receiver displays an empty message if no position is computed.
Example
Enter the following command to enable position message on port B.
$PASHS,NME,POS,B,ON
$PASHQ,POS,x
The associated query command is $PASHQ,POS,x where x is the optional output
port.
$PASHR,POS
The response is a message containing information on the most recently computed
position. This response message is in the form:
$PASHR,POS,d1,d2,m1,m2,c1,m3,c2,f1,f2,f3,f4,f5,f6,f7,f8,f9,s*cc
Table 8.39 defines the POS response structure.
Field
d1 position type:
0 = autonomous
1 = position differentially corrected
d2 Number of satellites used in position computation
m1 Current UTC time, (hhmmss), of position computation
in hours, minutes and seconds
m2 Latitude component of position in degrees, minutes,
and fraction of minutes (ddmm.mmmm)
c1 Latitude sector: N = North, S = South
m3 Longitude component of position in degrees, minutes,
and fraction of minutes
c2 Longitude sector: E = East, W = West
f1 Altitude in meters above WGS-84 reference ellipsoid.
For 2-D position computation this item contains the
altitude held fixed.
