GNSS-IR水位变化监测标准潜在需求研究OA

As an emerging means of surface environmental monitoring,the Global Navigation Satellite System Interferometric Reflectometry(GNSS-IR)technology plays a crucial role in enhancing the efficiency of water resources management in China and ensuring the accuracy and timeliness of water level monitoring.Currently,there is a lack of unified standards to regulate the relevant technical methods,operation processes,and application of achievements.This paper focuses on exploring the potential needs for the standard of GNSS-IR water level change monitoring.Through the categorization and systematic review of the involved water body types,monitoring equipment,band characteristics,evaluation indicators and so on.This paper deeply analyzes the current standard situation of GNSS-IR at home and abroad,and systematically studies the construction framework of the technical standard system of GNSS-IR in China.The aim is to provide a reference for the standardization construction and promotion of GNSS-IR technology in China,and further improve the application level and industry influence of China in this technical field.
