Effect of atmospheric turbulence anisoplanatism toward LEO satellite-to-ground laser communications link

During Low Earth Orbit (LEO) satellite-to-ground laser communication (SGLC), atmospheric transmission conditions exhibit dynamic variability along the satellite’s trajectory. This spatiotemporal variation gives rise to anisoplanatism in atmospheric turbulence across different optical paths. To investigate this phenomenon, this project provides datasets including star maps and atmospheric turbulence intensity estimations. These datasets were obtained using the Atmospheric Turbulence Measurement System (ATMS), which enables multi-path monitoring of key turbulence parameters.
