The Beidou surface rainfall prediction equipment is a product developed in response to the "three lines of defense" initiative of the Ministry of Water Resources. It is based on Beidou navigation satellite communication application technology and achieves real-time monitoring and forecasting of regional high-resolution surface rainfall. By integrating deep learning artificial intelligence algorithm models, it can provide real-time nowcasting and short-term and imminent weather forecasts (0-3 hours) for rainfall within a 30-square-kilometer area above a single GNSS monitoring station. It can be widely applied in meteorology, hydrology, natural resources, emergency response, scientific research, and other fields.
