Min. 1m Figure 1. Antennas Courtesy of Northstar BNT, Acton, MA Choosing the Mounting Location For accurate readings and a reliable GPS signal, selecting the best location for the WeatherStation is very important. Easy access and appearance should be secondary considerations. Since each installation is unique, the best separation distances from other equipment on the boat will vary depending on the particular equipment and how it is configured.

Appendix A—How the WeatherStation Works About the Ultrasonic Wind Sensor The ultrasonic wind sensor (an ultrasonic anemometer) measures apparent wind speed and direction. The WeatherStation contains four ultrasonic transducers, visible through the four holes in the top of the sensor’s wind channel (see Figure 48).
Page 63
Consider the case of a vessel proceeding at a speed of 15 knots in calm air. An observer on board would experience a wind of 15 knots from dead ahead. This apparent wind would be due solely to the motion of the boat. If a true wind of 15 knots was blowing from the stern, an observer would experience dead calm—no apparent wind.
Page 64
About the Electronic Compass The WeatherStation includes a pair of magnetoinductive sensors that measure magnetic field strength in two axes on the horizontal plane of the WeatherStation. From these measurements, it calculates the resultant magnetic heading angle, thereby providing a built-in electronic compass. Like all magnetic compasses, the WeatherStation compass will be affected by any ferrous or magnetic materials in the vicinity, such as metal structures, motors, speakers, etc.
Page 65
About the Air Temperature Sensor The WeatherStation includes a built-in negative-temperature-coefficient thermistor that measures the ambient air temperature. This NTC thermistor is located in a thermally isolated region of the WeatherStation housing that is open to the outside air. About the Relative Humidity Sensor The WeatherStation contains a capacitive cell humidity sensor that measures the relative humidity of the air.
Page 66
About the Barometric Pressure Sensor The WeatherStation contains a temperature-compensated, silicon, piezoresistive, pressure sensor. It measures atmospheric pressure for use as a digital barometer. While a single measurement of air pressure at a given location has little value, the trend of changing pressure and wind over time can be a useful tool in performing basic weather forecasting.
