Abstract: Satellite Internet is a new type of global and all-time network information infrastructure that uses large-scale satellite networking and is supported by aerospace, communication, network, and data technologies. Compared with traditional satellite networks, it offers advantages such as wide coverage, low latency, high bandwidth, and low cost. The challenges faced by new power systems in the construction of information capabilities are analyzed, including wide-area coverage, resilience to damage, and vertical applications. The definition and capability characteristics of high, medium, and low Earth orbit coordination in satellite Internet are refined, and practical pathways of satellite Internet enabling new power systems in areas such as power planning, situational awareness, inspection and maintenance, and disaster prevention and emergency response are proposed. A zero-trust satellite-ground fusion based integrated network information security system is proposed to serve as a foundational reference for the establishment, operation, and advancement of a comprehensive integrated space-air-ground and coordinated communicationnavigation-remote-sensing new power system. The new-style productivity level is enhanced.
