First of 2 Australian NBN Satellites Launched Successfully
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.

Religous speak to God. Insane are spoken to by God. When all shut up, one can finally hear Shostakovich in peace
What are the data usage limits on the new service or the cost for that matter?
Quick check on google turned up this article on gizmodo australia; "Satellite NBN Customers Are Reportedly Getting Shafted On Their Data Caps" http://www.gizmodo.com.au/2015...
Minimum threshold fixed. Thanks!
You're right, this is a complete waste of time. I don't know why they bothered.

No sig today...
The article seems to have failed to mention the price point for the service. That's a big sticking point with satellite broadband.
I read the internet for the articles.
the second communications satellite built in Argentina!!!
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. Some popular online games can be played with high latency; I know of EVE players that play successfully over satellite. That game only updates clients about four times a second at best.... so another quarter second of lag isn't that big a deal.
If your alternative is living in the dark then tens of megabits of high-latency bandwidth is pretty damn appealing.
Maw! Fire up the karma burner!
Maybe they plan on using it for more important things than games?
So, a google search for "Australia remotest town" comes up with Telfer, 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.
Lost at C:>. Found at C.
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.
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 even be used to service parts of Africa and South America.

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.

I agree
note: i'm known as plugwash most places but i screwd up registering that here somehow in the past and now can't register
This is the beginning of the end.
You are welcome on my lawn.
I didn't see one Foster's logo anywhere on the launch vehicle. There not Aussie's then. Probably the launch was from Malaysia.
Sky Muster Satellite Launch
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.
