Zusammenfassung: | Advanced Space-based Solar Observatory Satellite (ASO-S) is a space project sponsored by the Chinese Academy of Sciences; its goal is to monitor solar activities during the 25th solar cycle. Data from ASO-S is open to all scientists who are interested in it. It is expected to collect raw scientific observations of the Sun, which probably lead to more discoveries about the Sun. As the core members of the ASO-S mission, the authors of this paper have privileged rights to handle the first-hand data from ASO-S. Based on the raw data transmitted from ASO-S, the authors focus on the orbit variation with time, quick-look products of 3 main payloads. First, the authors collect the precision orbit elements provided by the onboard GNSS receivers; with the help of professional orbit analysis software, as of Dec. 14, 2023, orbit altitude and local time of descending node are derived. Second, three quick-look products from three different payloads are derived by means of preliminary image processing techniques. Based on the above-mentioned analyses, it has shown that the orbit for ASO-S is slightly changing and stable, which has little influence on ASO-S mission operation; quick-look product quality indicates that the status of payloads is healthy, which can support ASO-S mission to run smoothly and continuously during the rest of its lifespan. |
