$PAMTC,
ALT
Summary
Settings related to the altitude of the WX Series WeatherStation Sensor.
Syntax
One of the following forms:
$PAMTC,ALT,SET,<2>,<3>,<4>*hh<CR><LF>
$PAMTC,ALT,Q*hh<CR><LF>
Fields
<2>
Fixed altitude, -999.9 meters to +40,000.0 meters, to the nearest 0.1
meter.
Default value = 0 meters
<3>
0 = Do not use fixed altitude for GPS 2D mode
1 = Use fixed altitude for GPS 2D mode
Default value = 0
<4>
0 = Do not use altitude for barometric pressure altimeter setting
($WIMDA, fields 1 and 3)
1 = Barometric pressure altimeter setting uses fixed altitude (field
<2>).
2 = Barometric pressure altimeter setting uses GPS altitude when
GPS has a 3D fix, or fixed altitude (field <2>) when GPS does
not have a 3D fix.
Default value = 2.
Notes
The $PAMTC,ALT,SET,<2>,<3>,<4> command is used to program the WX
Series WeatherStation Sensor with a fixed altitude setting to be used in
calculating a more accurate GPS position when the GPS is operating in 2D mode,
