The OWS-5 provides a measurement of wind speed and direction relative to the ground from a moving platform such as a sailing or rowing coach boat (RIB), regatta committee boat, cycle race chase cars, wind turbine transfer vessels, ferries etc. The great advantage of OWS-5 is it requires no calibration when in use.
OWS-5 uses the solid-state ultrasonic Gill WindSonic wind speed and direction sensor. This 2-axis ultrasonic wind sensor is robust and maintenance-free making it the sensor of choice for harsh environments eliminating the problems associated with more conventional cup and vane sensors.
The orientation of the WindSonic sensor and its movement relative to the ground is measured using a GPS compass from this the ground wind speed and direction can then be calculated knowing the motion of the WindSonic sensor and the measured wind speed and direction. Data is transferred over WiFi to a tablet or smartphone within 20 metres. In addition data is also sent via the mobile cellular network to the WeatherFile website where it can be viewed by any internet connected device from any location.
