You can look at the https://satellitemap.space/ to see that starlink isn't (yet) too feasible in the northern/arctic areas. Even in the Nordic countries the connections are not that great.
>> We're talking backup vs. primary. Of course the backup is not going to be as good.
Then it isn't really a backup. A lower-bandwidth failover capacity is properly described as an alternative or degraded pathway. To be a proper "backup" a thing has to actually do the primary job at least temporarily.
aye. Starlink could be, best case, an Out of Band (OOB) management interface.
good for getting into the other side of a connection or doing some management tasks like back-up telemetry -- but we're talking SNMP, SSH connections to routers, etc, not GigE levels of data.
It's a good idea for future satellites, but upgrading existing satellites is probably not feasible.
And these polar orbit satellite typically live a lot longer than the relatively short lived starlink satellites, potentially opening you to a (perhaps unlikely?) scenario where starlink moves to new and incompatible hardware for inter-satellite communications, and your satellite is then made obsolete.
Vertical integration is not cheap, but it does have it's upsides.
That would require replacing all the satellites with new ones capable of doing that, which doesn't seem feasible. Starlink also doesn't have great coverage of the polar regions.
“We're passing over terabits per second [of data] every day across 9,000 lasers,” SpaceX engineer Travis Brashears said today at SPIE Photonics West, an event in San Francisco focused on the latest advancements in optics and light. "We actually serve over lasers all of our users on Starlink at a given time in like a two-hour window.”
Again though, you can't do "Starlink from the satellites, so we don't rely on a specific ground station" unless all of the satellites support talking to Starlink, which they don't. That means they'd have to be replaced.
As I understand it, the Starlink network has a number of ground stations, and an active inter-satellite "mesh," thanks to laser links, which would allow it to route around the loss of one or more ground stations? (although obviously it requires at least one ground station to be live in order to access the non-Starlink-connected Internet)
The lasers began being integrated between 2020 and 2021, so it's likely SpaceX has made decent progress equipping their network with this capability, although I can't find the latest figures for the proportion of satellites that have lasers.
It sounds like there's something I'm missing if we can't do "Starlink from the satellites, so we don't rely on a specific ground station"
Do you understand what the problem trying to be solved is?
There are satellites in orbit today that have nothing to do with Starlink. Some of these have been up for a long time. We're talking weather satellites and research satellites. The ones in a polar orbit can only use one of two ground stations to communicate back with the earth, simply due to their location. One of those ground stations has lost it's fiber optic connection so it can't be used at full bandwidth right now.
None of that so far has anything to do with Starlink. We're talking about a system os satellites that already exists and predates Starlink sometimes by decades.
The person that started this thread proposed: "Maybe just use Starlink from the satellites, so we don't rely on a specific ground station." In other words, have these already existing satellites integrate with the (relatively new) Starlink system.
So they're saying that we somehow make those old satellites, which are already in orbit and have their own communication systems designed to interface with ground stations, somehow stop using the ground station and start using Starlink instead.
It is just one tap, right on the top, not that hard and that the algorithm starts showing you stuff by default before new people follow enough is not that evil is it ?
I didn't say it's evil, but the site is trying to bias you into "engagement". Yes, it's one tap, one tap every time I load the site, plus the four seconds it takes for the new view to load.
Similar to some tendencies today with Right Wing from German AfD or American MAGA to dismiss complete fields of science. Whether it is climate change or vaccinations. They do not have a discussion, they dismiss it outright.
