| Jan 1, 2022 at 12:29 | comment | added | Ludo | @uhoh Your quote is from the 2305 encounter; for 1095 there is no mention of tracking difficulties. As I understand it, 1095 just moved from one orbit to another without notification, coming close to the CSS. In any case, in both situations the separation was considered (by China) to be dangerously small, and I am curious to know how small, even if the error bars were big. | |

| Dec 31, 2021 at 17:50 | comment | added | uhoh | Your summary of the complaint "getting so close to their Tiangong Space Station" misses an important point in the complaint that both satellites were said to be continuously maneuvering and so collision prediction was difficult. "As the satellite was continuously manoeuvring, the manoeuvre strategy was unknown and orbital errors were hard to be assessed..." Certainly "how close did they get" is a valid question that can be answered (within several km errors) from TLEs, but the complaint was in large part about the unpredictable maneuvering which led them to give the Starlinks a wide berth. | |
