Abstract

Compared with Radio Frequency (RF) communication

satellite-to-ground laser communication offers significant advantages including ultra-large bandwidth

high data rates

enhanced security

and low power consumption. It is a key enabling technology for constructing integrated space-air-ground information networks and supporting 6th Generation Mobile Communication Technology (6G) and future satellite internet development. This paper systematically reviewed the research process and current development status of satellite-to-ground laser communication both domestically and internationally

and summarized recent Chinese standards and technical advancements in this field. The paper focuses on three critical technologies in satellite-to-ground optical links: Adaptive Optics (AO) systems

atmospheric turbulence prediction techniques

and Acquisition

Tracking and Pointing (ATP) technologies. The paper elaborated on their underlying principles

presented recent research progress

and highlighted representative achievements. Furthermore

it discussed future development trends to provide a reference for ongoing and prospective research in this domain.
