Marine Weather Station
Our Marine Weather Station is a multifunctional measuring instrument. It can accurately measure and display real-time relative wind speed and direction, true wind speed and direction (with GPS input), air temperature, relative humidity and atmospheric pressure. And it also can print out parameters such as time, longitude and latitude, ship speed and navigation signals. It is very important and necessary for observation and safe navigation.

Working principle
1. Wind sensor sends relative wind direction and speed signal (relative to ship bow and absolute value of angle signal) in digital interface format of RS422 to main unit through junction box.
2. Temperature and humidity sensor provides air temperature and humidity signal in digital interface format of RS22 to main unit through junction box.
3. Barometric pressure signal is received from internal IC sensor of
4. main unit.
5. Main unit uses these signals to calculate, display and export true speed and direction. There are two ways to get the true direction and speed.
(1) Connecting external GPS (RMC) data input, main unit can calculate true wind direction (relative to North Pole) and speed.
(2) Connecting both Gyro(HDT) and Speed Log(VBW) data, main unit can display the true wind direction and speed.
