First of 2 Australian NBN Satellites Launched Successfully 58
New submitter aduxorth writes: Sky Muster, the first of the two satellites that will comprise Australia's NBN's Long-Term Satellite Service, has been successfully launched from Guiana Space Centre in South America. The two geostationary satellites will offer a total capacity of 135 gigabits per second, with 25/5Mbps wholesale speeds available to end users. The second satellite is expected to launch next year. Testing of this satellite will start soon and will continue until services are launched early next year.

The latency is bad, but not that bad. Earth to geostationary and back round trip is about 250ms. Switching hardware and ground relay adds a few tens of milliseconds more, so typically you're well above 250ms but not usually more than 300ms. 700ms is some other problem; congestion or something.
But yes, the long round trip makes these systems unsuitable for low latency applications; certainly real time gaming is impossible, but also even just voice communication becomes awkward with that much delay. Som

The 700ms is probably talking about the network RTT seen when you ping a host as the data is travelling up to the geostationary satellite and back twice, once as it goes from you to the end host and then once again on the return trip.
However most network traffic doesn't behave like that, TCP doesn't acknowledge every packet in a connection, so not everything would suffer that kind of delay.

Network latencies are usually quoted as "round trip time" (that is the time from sending a packet to the server to getting a reply back). The round trip between you and the server passes through the sattelite twice so that brings you up to 500ms.
And that is for a link where you have a timeslot availible already. If you have to request a timeslot from the sattelite before transmitting then you just added another 250ms.
If your alternative is living in the dark then tens of megabits of high-latency bandwidth is pretty damn appealing.
I agree

Maybe they plan on using it for more important things than games?
So, a google search for "Australia remotest town" comes up with Telfer [wikipedia.org], which sounds like it's so far past the arse end of nowhere as to be unimaginable to most of us.
When everything is hours away (if not days), 700ms latency is probably quite a step up.

The other alternative is lots of satellites in a low earth orbit, with one coming into a range as another one leaves and some kind of data relay mechanism for sending data to a base station. A more complex solution but latencies would be much lower and it would probably scale better. The same satellites could eve

That's ideal, but the problem (as seen with Iridium doing that) is getting enough people around the planet to agree to pay for it. It's a management/diplomacy problem that gets in the way of an ideal technical solution.

So the solution to that is to launch at the cost of hundreds of millions of dollars a couple of satellites, which might last 15 years tops. I would have serious doubts that this is cheaper than running some fibre even in the short term let alone the long term.

Me, I'm thinking by the time you build and launch the satellites you've give it some thought, and that random comments on the internet aside, have probably concluded it is worth it ... by whatever metrics you use to make that decision.

What business model would that be? It is Australia's NBN which is a government funded scheme to provide a new national broadband network. Most of the 400,000 premises that the NBN satellite connect will be in remote small towns. Places like Coober Pedy not stations in the middle of nowhere.
The NBN satellite program is around 1.5 billion USD, that is an awful lot of fibre optic cable, and in 15-20 years time when the satellite packs in will need to be spent again, while the steel armoured fibre will be doin

Well there are plenty of big cities on both sides of Australia, and just outback in the middle. I don't know either way but I'd be *really* surprised if there is really no cables running through the outback connecting them (phone, data etc).

People who are not from Australia seem to find it difficult to understand how empty the middle of Australia is. Running thru the Outback(in this case places like the Great Sandy Dessert) is like running cable thru Mars.

Really they seemed to manage running a telegraph cable through the middle of Australia in two years ending in August 1872 at at time where there was not even a map of the interior of Australia. I conclude that running some fibre 150 years later is not unreasonable.

You do understand quite how the population of Australia is dispersed right?
Well let me help you with it. Australia is only a bit smaller than the USA and has less than 1/10th of the population. The population we have is heavily centered around a handfull of major cities on the east, west, and south coast with two minor cities up north. Inland there is nothing. We don't have a Dallas, we don't have a St Louis, no Oklahoma city, or a Denver. What little population we have in the bush is highly decentralised t

There is already expensive satellite coverage - the plan with these two satellites is cheap and much higher capacity than linking to a satellite over Dubai that charges a lot more per kb and could never handle the volume of customers that is planned.

The other reality of course creating and maintaining road roads is hugely more expensive than laying cable, many orders of magnitude greater. So if they are serviced by a public road at a huge loss to the state (considering traffic volumes) than why is a cable strung between poles such a nation bankrupting exercise or is the assessment being based purely upon greed and the desire for unlimited profits. Keep in mind the fibre optic cable is cheaper than laying the equivalent existing copper service over tha

It is nice to see that they offer some personal hosting space. And that they're still running it off of the 1998 machine they originally set up for it with the 1GB HDD so they can only give people 25MB of space. You don't see those much anymore.
No IPv6 support is a bummer too. If you are launching a bird in 2015, the service should support IPv6.
