Mr. Ran, you just introduced that the Beidou's goal is to build a more ubiquitous, integrated, and intelligent space-time system. Can you explain the specific meaning of this goal? What more needs to be done to achieve this goal? Thank you.

Ran Chengqi:

I have sort of answered this question just now. Everyone has paid great attention to Beidou-3. It is really good. Will there be anything better than it later on? Our answer is yes. For Beidou-3, we should ensure that the system itself continues to improve. How to develop it into the next generation of BDS? First of all, we should build the next-generation BDS, likely BeiDou-4, to be better. This system will make further breakthroughs. First, for the satellite constellation, we now have medium-orbit and high-orbit satellites. In the future, we will also consider including low-orbit constellations to build a navigation constellation for high, medium, and low orbits. In addition to providing reliable and better performance in positioning and navigation services, there's the high-precision positioning service as I mentioned earlier. Everyone feels it is great to use, but that service is only applicable inside China. Can we push this network to be used universally? This is our expectation for the future. We particularly hope to provide such a high-precision, highly reliable, and powerful space-time network through the integration of high, medium, and low-earth orbit constellations as well as the integration with mobile communications and low-earth orbit communications. We especially hope that after construction is completed, users all over the world can share the positioning accuracy of 5cm, 2cm, 5mm, and 2mm. We have made a great demonstration of its technology, and the scheme is sound. We are very confident about its construction pace.

We also hope to lead the development of the global satellite navigation system and even the space-time field after the construction of the next-generation space-time system so that it is more ubiquitous, more integrated, and more intelligent. Being ubiquitous means the integration of various technologies and methods, including seamless coverage, which aims to solve all the problems related to space. General Secretary Xi encouraged us to "explore the vast universe," and we will go further and go to deep space. We should rely on China itself for our space-time benchmark. Whether there is a space-time benchmark in the far space of the Milky Way Galaxy... we are also working hard on it. We believe that the next generation of space-time benchmarks can solve this problem. I want to say we are looking forward to a promising future. The year 2035 is our goal. We hope to do better on this basis to make Beidou's highly reliable and high-quality services available at any time. Of course, through such high-quality services, we will also promote the development of the economy, society, and industrial chain and make new contributions to national economic and social development. Thank you.
