Abstract:In order to verify the consistency of the observation data of various elements of the shipborne automatic meteorological station under different navigation attitudes,the article designed a comparative observation test method for maritime navigation.The shipborne automatic meteorological station is fixed on the deck of the same test ship according to certain rules.Fix the shipborne automatic weather station on the same test ship deck according to certain rules,and the tested ship navigates along the designated route to obtain real-time observation data of the shipborne automatic weather station under different navigation attitudes.Propose a calculation method for the consistency index of sensor observation data suitable for comparative observation of maritime navigation,and analyze the consistency of sensor observation data such as wind speed,wind direction,temperature,relative humidity,and air pressure.The experimental results indicate that changes in navigation attitudes do not significantly affect the consistency indicators of the relative humidity and air pressure sensors of the shipborne automatic weather station,but affect the consistency indicators of wind speed and temperature sensors in some stages and cause deviations in the consistency indicators of wind direction sensors.The research results have a positive impact on improving the level of maritime meteorological services.
