Estimation of the laser guide star uplink tip-tilt using aperture size diversity
Pierre Jouve, Thierry Fusco, Carlos M. Correia +3
The paper proposes a method to estimate the uplink tip‑tilt of a laser guide star using only telemetry from the launch telescope, by exploiting aperture size diversity and an LMMSE…
