Hadn’t appreciated a home dish or whatever would transmit back to a moving satellite. Quite cool tech The dish tracks the satellites as they move. An academic did some modelling of the capability here, and how the handoffs work, based on FCC data https://www.youtube.com/watch?v=m05abdGSOxY He has a couple of other videos, SpaceX want the satellites to be doing satellite to satellite communication in the future. He works out whether it could be faster than the fibre across the Atlantic. 1 Quote Link to comment Share on other sites More sharing options...

For most people down is much more relevant to performance but every time you fill in a form, send a search, reply to a pointless post it’s an upload 1 Quote Link to comment Share on other sites More sharing options...

It was cheaper and easier than getting users to transmit back up that high. That's what The Old Git was on about. Edit: "One-way receive, with terrestrial transmit" was the technical name for it.

A previous satellite system relied on a wired uplink. Quote Link to comment Share on other sites More sharing options...

It’s cone a long way since my first 24 whatsit dial up modem. Or was it 12?

Overdose Posted August 1, 2021 Share Posted August 1, 2021 (edited) As the guys said, it's all done through a dish to the satellites for down/up traffic at the users end. The ground stations are what links the satellites to the internet data centers. ETA: Here's a link that shows all the Starlink satellites https://satellitemap.space/# Edited August 1, 2021 by Overdose Quote Link to comment Share on other sites More sharing options...

Now invite them to use us as a test ground for autonomous vehicles and get the PR machine rolling. Watched the latest Grand Tour special filmed in lockdown yesterday and it just struck me as another missed opportunity. Great shots of Scotland and huge worldwide audience and we were open most of last summer and they could have come here. Our government should be all over stuff like this, there are enough of them.

Derek Flint Posted August 1, 2021 Share Posted August 1, 2021 Getting Elon Musk to put in a bid for the whole lock stock and barrel of the Island, installing him as a benevolent dictator would potentially be the saviour of the place. He’s the greatest visionary of our time, and anyone that can get a rocket to land on its tail gets my vote. 2 1 1 Quote Link to comment Share on other sites More sharing options...

Absolute bollocks. What do you want, communism?. We actively need some true industrialists to jump start the economy. If not then we're truly fucked.
