Yes, but you're already bandwidth constrained when getting grib files through a satphone which often means using coarser grids over a smaller area (constraining your options) less frequently. Not the largest limitation, but better bandwidth would be useful.

As you point out, it's largely a value judgement between worldwide fast internet and ground based optical astronomy and it's one I'm conflicted about. I comfort myself with the thought that because of the expense these constellations either will bring internet access to large numbers of people justifying continuing satellite replacement or they'll fail and the satellites will be gone sooner rather than later, but as I say, I'm conflicted.
