Optical metrology terminal for satellite-to-satellite laser ranging [PDF]

open access: yesInternational Conference on Space Optics — ICSO 2018, 2019
Interferometric laser ranging is an enabling technology for high-precision satellite-to-satellite tracking within the context of earth observation, gravitational wave detection, or formation flying. In orbit, the measurement system is affected by environmental influences, particularly satellite attitude jitter and temperature fluctuations, demanding an
