POS: 3-D Antenna Position
$PASHS,POS,m1,c2,m3,c4,f5
This command sets a 3-D antenna reference position for a differential base station
receiver. m1 is the latitude, c2 is the latitude (N or S) sector, m3 is the longitude,
c4 is the longitude sector (E or W), and f5 is the altitude. Use the
$PASHQ,RTC
command to verify that the desired coordinates are in effect.
$PASHS,POS,CUR
This command sets the current computed position as the reference position for a
differential base station receiver. This setting is useful in some applications which
do not require absolute accuracy. Remote receivers getting differential corrections
from a base station whose reference position was entered using this command can
still compute very accurate positions relative to the base station.
This command is not accepted when a position is not computed.
$PASHQ,POS,[c1]
This command queries the receiver’s current 3-D position, where c1 is the optional
port designator for the output of the response message. If a port is not specified,
the receiver sends the response to the current port.
$PASHR,POS
The response message is output in the format:
$PASHR,POS,d1,d2,m1,m2,c1,m3,c2,f1,f2,f3,f4,f5,f6,f7,f8,f9,

Parameter Description Range
m1 Latitude measured in degrees, minutes, and
decimal minutes (ddmm.mmmmm) 0° to 90°
c2 Latitude sector N or S
m3 Longitude measured in degrees, minutes,
and decimal minutes (dddmm.mmmmm) 0° to 180°
c4 Longitude sector E or W
f5 Altitude (±aaaaa.aa) ellipsoid height in
meters. In 2-D positioning mode, this field
contains the fixed altitude value -3000.00 to +3000.00
