Abstract: Starlink, asatellite broadband constellation operated by SpaceX, is currently the most influential and promisingLEO (Low Earth Orbit) broadband satellite constellation. With the expansion of the constellation deployment, its high-frequency launch and batch deployment of satellites, provision of diversified satellite broadband services, rapid growth of global user terminals, as well as potential support and capabilityenhancing for military are manifesting gradually. In this paper, we first analyze the current status of Starlink's on-orbit operations, and compare its Internet services with other satellite broadband service providers. Then, weinvestigate the application characteristics and technical challenges of Starlink's inter-satellite laser links, and discuss Starlink's military application progress and the evolution trend.Finally we summarize the comprehensive application advantages Starlink offers, and technical challenges faced by Starlink, which can serve as a stepping stone for the design of our country's satellite network. Overall, the construction and application of a mega LEO constellation like Starlink involves thechain integration of a series of component, ranging from satellite design and industrialized production, satellite launch facilities, constellation operation and maintenance, satellite networking, toglobal ground station supporting, rather than just the satellite platforms.
