Problems solved by technology

One of the most basic and key aspects of Beidou’s high-precision geological disaster monitoring is the perception and data collection of on-site conditions. Rainfall is closely related, and there is no mains access at the monitoring site. In the initial stage, the positioning accuracy of the antenna needs to be verified. The document of Chinese Patent Application Publication No. CN103235328A discloses a method of GNSS and MEMS integrated navigation, combining GNSS and MEMS Accelerometer and gyroscope data can improve the accuracy of integrated
