Wind Speed and Direction


Measures speed and direction (relatively to the ship)
True direction calculated by the software (using speed, heading and
the true rout of the vessel)
Young 05106
•Resolution: 0.2 kn
• Useful range: 0 to 120 kn
• Wind direction resolution : 3
degrees
BATOS II : CV3F Ultrasonic Wind
Sensor (LCJ Capteurs)
New generation wind speed and
wind direction measurement
device
• Resolution: 0.1 kn
• Useful range: 0.5 to 99.5 kn
• Wind direction resolution : 0.1 degree
• Temperature range : 0 to 40°C
Screen
Miniature marine SOCRIMA
Naturally ventilated multi-plate screen providing
a good protection of temperature and humidity
sensor
Enclosure : 20 cm (D) x 50 cm (H)
To be installed on the deck
Software
Checks the measurement to ensure data quality
Generates normalized weather messages (code 41) every 1, 3 or 6
hours
Sends on automatically the messages via satellite
Data storage (hourly, during 6 months)
Sensor data display in real-time and help for human observation
capture
Communication
