one of the other satellite architectures that could address the South Pole high bandwidth access problem, basically the same thing as o3b, but in 90-degree inclined polar orbits. The o3b meo satellites are generally visible anywhere within plus or minus 45 degrees latitude from the equator, because they are in Equatorial orbits. But if there was sufficient market demand there is nothing to say that a highly inclined orbit, similar system could not be deployed.

the existing starlink test satellites are in highly inclined orbits, so if there were a great deal more of them, this would also be a possible solution.
