Review of marine environment monitoring methods based on GNSS technology
Real-time,accurate and reliable monitoring of marine environmental information plays a crucial role in marine disaster warning and prediction,disaster prevention and reduction,marine resource development,and ensuring marine safety.In recent years,with the continuous development and upgrading of global navigation satellite systems(GNSS),the detection of atmospheric and marine environmental information based on GNSS navigation signals has become a new method and a hot research topic in the marine environmental monitoring technology.This method has been widely applied to domains such as marine meteorological monitoring and numerical forecasting.This article systematically reviews the current research status of the GNSS technology in marine environmental monitoring,including effective wave height,wind speed,rainfall intensity,water vapor and tide level monitoring.Furthermore,this paper systematically summarizes new technologies and methods and looks forward to provide reference for the future research in related fields.
