Payload Scheme Research Based on Flexible Access Strategy of Satellite Constellation

In recent years, SpaceX’s Starlink program is rapidly staking their claims in this market, and China is not shy to vigorously develop low-orbit Internet satellite constellations. Both low-orbit Internet constellations and other satellite constellations aim to achieve high global coverage with real-time data transmission and low latency, which are incomparable to terrestrial network systems in all dimensions. It not only has important strategic significance, but also meets rich commercial needs. The topology of the satellite constellation is time-varying and cannot form a stable transmission model like the terrestrial Internet of Things. Therefore, the flexible access technology of satellite payloads directly affects the operation of the constellation and user experience. This paper combines the current development status of satellite payload technology, according to different business needs and different application scenarios, studies the pay scheme, involves microwave, laser and multiple-access technologies, and proposes a rapid inter-satellite access idea. It is hoped that through research, ideas can be inspired to promote the research and development of satellite payload fast access strategy.
