Het volstaat dus om alleen de getallen voor windrichting en windsnelheid te vervangen door de ware windrichting en snelheid. De repeater zal altijd deze zinsopbouw en parameters willen zien vermoed ik.
$WIMWV
Summary
NMEA 0183 standard Wind Speed and Angle, in relation to the vessel’s
bow/centerline.
Syntax
$WIMWV,<1>,<2>,<3>,<4>,<5>*hh<CR><LF>
Fields
<1> Wind angle, 0.0 to 359.9 degrees, in relation to the vessel’s
bow/centerline, to the nearest 0.1 degree. If the data for this field is not
valid, the field will be blank.
<2> Reference:
R = Relative (apparent wind, as felt when standing on the
moving ship)
T = Theoretical (calculated actual wind, as though the vessel
were stationary)
<3> Wind speed, to the nearest tenth of a unit. If the data for this field is
not valid, the field will be blank.
<4> Wind speed units:
K = km/hr
M = m/s
N = knots
S = statute miles/hr
In the WeatherStation, this field always contains "N" (knots).
<5> Status:
A = data valid; V = data invalid
Default State
MWV(R): Enabled. Transmitted twice per second.
MWV(T): Enabled. Transmitted once per second.
Notes
Depending on the contents of the Reference field (field <2>), this sentence
provides either relative (apparent) wind or theoretical (true) wind data, both in
relation to the bow of the vessel. As it is conceivable that both of these forms
could be useful simultaneously, the WeatherStation by default outputs this
sentence twice, once in each form.
To enable/disable the theoretical (true) form of this sentence, use the
$PAMTC,EN,MWVT command. To enable/disable the relative (apparent) form,
use the $PAMTC,EN,MWVR command.
