Monitoring, research, and forecasting of space weather in the Earth-Sun system have a direct impact on the stable operation of high-tech systems such as spacecraft in-orbit safety, navigation and positioning, and wireless communication. Conducting re

In recent years, the Sub-Moon project has been applied in many scenarios. For example, when astronauts go out of the spacecraft, we conduct space weather forecasts ahead of time to avoid going out during solar storms or when there are high-energy par

The Meridian Project has formed a unique innovation monitoring architecture of one chain, three networks, and four focuses. The one chain refers to the complete observation chain from the sun's surface to the Earth's surface; the three networks refer

During the second phase of construction, many large-scale equipment could not be purchased, and many advanced technologies had no international precedent to follow. We increased our independent research and development efforts and explored and tried

To be honest, when we first started building, I was quite nervous. The large-scale equipment was highly complex, numerous, and we had a tight schedule. However, we trusted our team members, especially the young people's intelligence and wisdom. We en

With the integrated operation of the first and second phases of the Meridian Project, we are optimizing and enhancing the data processing software for some large-scale monitoring equipment. Looking ahead to the 15th Five-Year Plan, we will continue t
