On their website, SpaceX claims that Starlink satellites are able to conduct autonomous collision avoidance manoeuvres using alerts from the US Department of Defence. This seems very reasonable, given how many Starlink satellites are planned/already up there and given how labour intensive the standard, manual system is (NASA, ESA).
I am struggling to find any information on how their system works and was hoping someone here could point me to some technical papers. (My google scholar search brought up nothing, but I might be using the wrong keywords.) I am also wondering if anyone is aware of any other satellites that are able to (or planning to be able to) do autonomous collision avoidance manoeuvres.
Q1: Are there any technical papers on what techniques SpaceX is using for their collision avoidance systems on Starlink satellites? Or is their research mostly happening behind closed doors?
Q2: Are there any other satellites capable of autonomous collision avoidance?
