The tech is call "store and forward".
Prior to turbines, it was much more difficult to get dark from the rivers and lakes to the oceans. The Indians recognized this and tried to solve the problem.
When on a river canoeing, in the same direction as the flow of dark, they paddled slowly, so as not to stop the flow of dark, but when they traveled against the flow of dark, they paddled quickly to help push the dark along its way.

I just finished reading a book called Eccentric Orbits (great title! ) - The Iridium Story - by John Bloom
What a great book! Learned a lot about satcomms and how it works, Iridium's competitors and how restricted most of them are.
Iridium is still the only voice and data system with 100% guaranteed Earth coverage, minimal latency, and the only system with total orbital system hand-off...which means no ground station interaction and all the switching is done in orbit. So if you call another Iridium Satphone there is no problems if the ground stations are destroyed - they are there for diverting to landlines and mobile networks. I wondered why the military liked it so much.
So is this the best potential system for a group? Yes, Yes, people are going to go on about cost, EMP bla bla. What about for a spread out group (maybe a family) that decides to all come together if there is an emergency? Kept in the car or hand/man bag? Yes it might not be up for ever but initially you would have comms?
This would of been perfect for me in the Black Saturday fires when the mobile network was useless...
Someone in a ground-based office still has to tell the system you have paid your bill and your sat phone is authorized to use the network otherwise it won't work for long but in the initial first few days yeah they have a place in any kit. I have kept my Thuraya satellite phone as a tool for emergencies because of that reason if all the phone towers and network is down in my region due to a serious event I can still call people outside that area and get information from that area about what's happening in my area I do plan on in the very near future buying the starlink RV model due to the fact you can pause the payments and system as needed so having access to high-speed internet in certain situations can be a big advantage.

We have 5 starlink home services here, and have good internet, except for maybe 10 mins or so during a severe thunderstorm. Also, we apparently can wi fi the phone through the satellite and access e mails etc, and make limited calls.
The closer the collapse of an empire, the crazier its laws.

If you have wifi calling in your mobile you can use starlink to make calls that way. it’s good, no lag but does drop out every now and again. why 5 systems? surely you could link up wifi enabled modem to multiple routers and boost them if you need to.

I have kept my Thuraya satellite phone as a tool for emergencies because of that reason if all the phone towers and network is down in my region due to a serious event I can still call people outside that area and get information from that area about what's happening in my area Do you stll need to have a paid-up account, or can you somehow use he phone and exisiting non-thuraya sim card?

I'm in total agreement that in a total crash or global disaster, satellite comms is a downer for the long or even medium/shortish term. Even if you have say 24~48 hours of service, it would probably be enough to get your group/plan in order?
I guess I'm not interested in it much as I think its a very low probability of happening. I'm more interested in local disaster comms where people will still be manning the switchboard so to speak.

The reason for 5 systems is that everyone pays their own, and 5 systems with less total downloads was far cheaper than one bigger system with the issues of up to 9 users at once on it. Its good, but not that good !
Also, several stream TV over their internet, whilst two others use satellite TV (Fox-tel), another uses terrestrial though its pretty poor here, and I have an old vast box in the radio room, (gave up on terrestrial TV as the signal is just too far way and the dropouts were really annoying, even with twin stacked 40 element yagis and a 30 dbi gain amp).
We also have 2 landline phone services, which may keep working for a while afterwards. There is a wired intercom service between houses, but its switched off because of privacy concerns and its not needed yet.
Just did a check of the battery paks in the UHF gear and found one faulty. It was a very old Ni-cad pak, but zapping it brought it back to life. Maintenance is the key to having everything ready to roll.
I fix stuff, and I know things.

And here's where we can see that the big 'important' satellites aren't the only target for any entity interested in disrupting a country: Inmarsat I-4F1 satellite outage disables tractor GPS services for farming operations and some maritime safetyI find it very interesting that it's degraded the network over the Oceanic area rather than areas like, oh I don't know... The US? I haven't seen anything that says how or why the satellite was damaged either. It's a bit sus that Inmarsat haven't said what has caused the disruption yet. Only that 'recovery is underway'.

Modern large scale farming just can't be done without auto steering tractors\headers etc. There is so much to do and look after a operator just has not the time to steer as well. Standard GPS isn't accurate enough, and the high accuracy is via the satellites system that is down. Luckily, most winter planting is done here.
The most important rule in a gunfight is: Always win / cheat if necessary."

In the near future, satellites are going to be a big problem. There are just too many of them up there. It won't be long before a couple of them collide and make a massive debris field. It almost getting near to the point that there just won't be any safe windows left anymore to be able to launch rockets etc I support some international space laws about forcing countries to bring down obsolete or dead satellites to clear space up a bit, they even have satellite-capturing satellites now that "capture" a dead satellite in a net and drag it back down to earth. I see satellite warfare as another frontier in the future as well with governments using satellites to disable other governments' satellites to knock out comms/GPS/internet etc. Here is a visualisation just just how many satellites are floating around earth at the moment.

If/when WW3 breaks out, I suspect the satellite network will be a priority target. Unfortunately, once u destroy the enemy's satellite, yours is also now vulnerable to that same debris. Most satellites can be moved with thrusters, but when the fuel runs out, the old law of gravity takes over....what goes up must come down.
Those who rely on satellites for internet, comms TV news etc, will be in the dark. That's when your alternate arrangements of ham radio and a decent short wave receiver will be invaluable and put you back into the intel game.
Get it up and running now, before u need it. That's real prepping.
When in doubt, empty the magazine…. If the enemy is in range, so are you.

you have to have an active account thats paid up mine cost $16 a month and its free for others to call me and text me my account is through pivotel www.pivotel.com.au/plans-thuraya-satellite-phone-plans.html

I agree that there will be a short window of communications, probably less than 24 hours before the networks either shut down, or are destroyed. The satellite issue is one of exponential failure. First, one will get destroyed, then 2, then 10, then 100 and then thousands all at once, leaving a massive hole in the communications systems, and a mess above us. Should be some interesting nights watching all the debris re entering the atmosphere and burning up. And some of these satellites weight upwards of tons and wont necessarily burn up upon reentry, so there may be some deaths on the ground as well. There have been reports and pictures of satellite debris hitting roofs before, imagine that 1,000's times worse. en.wikipedia.org/wiki/List_of_space_debris_fall_incidentswww.space.com/topics/space-junkwww.bbc.com/future/article/20220912-what-happens-to-space-debris-when-it-returns-to-earthSo its a real issue. Always have a back-up plan, because the first one won't work.

Some SatCom services had a major outage recently,
Update: 12:25 17-Apr-2023 AEST (GMT +10) Inmarsat has advised that they have begun recovery procedures to restore services on the Inmarsat I-4F1 Satellite that provides service to the Asia Pacific Region including Australia and New Zealand. Due to the nature of the problem and the complexity of the recovery procedure, Inmarsat expects this to be an extended outage.
A further update will be provided at approximately 19:00 AEST.

The biggest problem would be the stuff that stays up there floating around crashing into more satellites, in a giant chain reaction until the near earth space is just too littered with debris that we can no longer launch any more rockets etc

There is a lot of space up there it is 3D environment. An EMP or emp nuke could potentially take them all down. That is the end of GPS and economy.... They are all heavily shielded for radiation, especially the ones that fly in and above the Van Allen belts...one EMP nuke isn't going to destroy them all, probably not even a few. Like you said; there's a lot space up there.

Like you said; there's a lot space up there. The satellites are venerable to solar EMP and man man made emp bombs.... www.washingtontimes.com/news/2022/feb/9/spacex-satellites-loss-solar-storm-highlights-emp-/Up to 40 satellites recently launched as part of a new Starlink internet communications system were damaged by a solar geomagnetic storm and are expected to fall to earth and burn up in the atmosphere, SpaceX, the systems’ manufacturer, announced Tuesday.
The loss of the satellites highlights the vulnerability of American civilian and military space systems to the damaging effects of a possible electromagnetic pulse (EMP) attack from an adversary, according to security analysts.
Starlink is a global network of low-Earth orbit satellites that provide high-speed broadband internet service, according to SpaceX, the commercial space company headed by Elon Musk.
“The loss of 40 Starlink satellites to a recent geomagnetic storm should be yet another wake-up call to Washington about the existential threat to our civilization from a solar superstorm,” said Peter Pry, a former CIA official and advocate for defenses against EMP and solar storms.

Step one, blind your enemy. Take out the satellites.
Step two, degrade, or even totally shut down the mobile networks, terrestrial internet and fixed telephones.
Step three, re introduce the woodpecker interference to the short wave bands to mask any comms. The military wont be left out as it will affect them as well.
Step four, confiscate the weapons from the populace. They know where they are as all are licensed.
Step five, push confusion over the mass media to muddle the real agenda.
Step six, set the people against each other, perhaps via food/water/electric/sanitation shortages.
Step seven, invade and subdue.
Are you ready for it ?
God will see to it, that his flock who has been so diligent to prepare, and aims to share, shall be well protected when that time finally does arrive.
