Abstract
A dual-comb absolute-ranging payload delivered to China’s Tiangong space station aboard Tianzhou-9 has demonstrated sustained on-orbit interferogram acquisition in an extravehicular environment. The system reports 13 µm precision at a 1 kHz update rate and stable operation over months, advancing traceable space metrology for formation flying and deployable observatories.Keywords
