Sure. But this won't provide it.
"the final fleet should be able to manage 1Gb/sec". So let's say they upgrade it to that speed. Say the satellite is above you for 5 minutes. You get to upload a whole 37.5GB of data; and that's assuming nobody else is uploading to it at the same time.
A gigabit of Internet transit bought in London costs less than £2,000 per month; you can use it 24x7 to any destination in the world. Obviously you need a fat enough connection at the other end too.
So where the satellite might help is:
(a) downlinking to places without decent Internet connectivity
(b) downlinking the same data to multiple places concurrently (say, all your stores in one country). But of course, if any of them fails to receive the data correctly, you have to send it out again on the next pass.
