Lasers learn to accurately locate space debris

The video discusses the use of laser telescopes and neural-network analysis to locate space debris. A study conducted at the Beijing Fangshen laser-range telescope station demonstrated the method's effectiveness. The technology, led by Ma Tianming, enhances the detection of small space debris with improved accuracy. Neural networks, inspired by human brain functions, are used to fine-tune telescope readings, significantly augmenting laser-ranging accuracy. This advancement allows for better pinpointing of orbital debris, enabling spacecraft to navigate safely and avoid space junk.
