Given an altitude of 500-550KM, what is the approx. beam footprint for these satellites (individually)?
But that may provide some information you find interesting.
Edit: this previous HN discussion also touches on this: https://news.ycombinator.com/item?id=21325720
Arc length along Earth's surface = R * acos(R/(R+h))
Where R is the Earth's radius, and h is the height above the surface.
I'm curious because a review of starlink that I don't think was all that dated, did some testing from a rural middle American ranch where they were unable to get a connection, supposedly due to the satellite being unable to connect to reach a ground station. The surface level reach of the satellites should have not been an issue though based on my calculations unless some base stations cam online since the testing done as part of the review I watched.
