– User Manual
Description
The WV command returns the wind velocity value in the currently selected format.
Polar, NMEA 0183 and Combined (Polar Wind & Temperature) data formats are available.
Use the DF command (Section 7.4.8) to select
the output format.
Polar Format: The sensor returns the magnitude of the wind speed (m/s) and the wind
direction (0-359°).
NMEA 0183 Format: The sensor returns the NMEA 0183 Wind Speed and Angle sentence
MWV (see WV NMEA, Section 7.4.30).
It is important that the status is always monitored. Readings associated
with errors should not be treated as valid. It is important that the host
computer is able to cope with occasional periods when valid data may
be temporarily unavailable.
The status is cleared once the WV command is executed, provided that
the error condition does not persist.
