SAILING TO WIN SAILING FOR LIFE Real-time weather station and GPS advancements Four ultrasonic transducers operate in pairs—one transducer injects a pulse into the air. The pulse bounces off the metal plate at the bottom of the wind channel and is carried by the wind to arrive at the listening transducer a short time later. When there is no wind, the pulse travels at the speed of sound from the sender to the receiver. Whenever the wind is blowing in that direction, the pulse will arrive sooner than if the air is still. Similarly, whenever the wind is blowing in the opposite direction, the pulse will arrive later than if the air is still. Wind Calculations

SAILING TO WIN SAILING FOR LIFE Real-time weather station and GPS advancements The four transducers take turns in sending and receiving pulses. A microprocessor within the WeatherStation then combines the measurements from all four transducers to calculate the resultant wind speed and direction. Throughout this process, the sensor monitors the air temperature, to compensate for the fact that the speed of sound in air changes with temperature. Wind Calculations receiving
