Low Earth Orbit Satellite Internet
A constellation system in which satellites operate at altitudes of roughly 300 to 2,000 kilometers, providing low-latency broadband coverage through large-scale satellite networking and inter-satellite links.
Timeline (last 90 days)
The threshold for the low-Earth-orbit satellite internet model lies not in single-satellite technology but in the combined capabilities of launch economics, constellation operations and terminal mass production, which is the core obstacle latecomers such as Rassvet need to overcome.
Low-Earth-orbit satellite internet (LEO) refers to satellite constellation systems operating in orbits about 300 to 2,000 kilometers above the ground.
The ground segment is often the most fragile link in the overall architecture of low-Earth-orbit satellite internet, because physical sites are hard to conceal, are relatively fixed in location, and have long construction cycles.
The available bandwidth of a single low-orbit satellite is typically on the order of a few Gbps to tens of Gbps, and the total capacity of a ten-thousand-satellite constellation at theoretical peak is only equivalent to the transmission capacity of a few high-capacity submarine cables.
The cost per bit of satellite links is far higher than that of submarine cables, and they are constrained by spectrum resources, weather attenuation and orbital capacity, so satellites are better suited to burst backup, polar or remote-area access and other scenarios rather than backbone international traffic.
The commercial logic of low-Earth orbit satellite internet is highly dependent on the dual accumulation of in-orbit scale and spectrum resources, with more in-orbit satellites yielding higher frequency reuse efficiency.
