Perhaps the calculations aren't straightforward Newtonian mechanics?

- konschubert 7y agoYou’re misunderstanding my comment. I wasn’t suggesting to not use AI algorithm for computing the collision probabilities. For this, they will obv use whatever tools they already have. The whole discussion is around how to react automatically to a likely collision.
- orbital-decay 7y agoPredictions based on TLEs aren't precise enough for satellite collisions. TLE is a solution compiled from many measurements, and what one wants for very close passes are raw measurements. It's a bit like JPEG vs RAW in photography. Regarding that particular collision, IIRC human factor was involved a lot. Iridium has been warned well in advance, but hesitated to make the decision since their models gave lower probabilities.
