Satellites Providing Internet To the 'Under-Connected' 50
Taco Cowboy writes "Today, a Russian Soyuz rocket shot the first 4 of 12 satellites in a new constellation that are designed to provide affordable, high-speed Internet to people in nearly 180 'under-connected' countries. The orbiters, part of a project dubbed O3b for the 'other 3 billion' people with restricted Internet access, were built by the Franco-Italian company Thales Alenia Space. They will orbit at 8,062 km and will weigh only 650 kilogrammes (1,400 pounds) each. 'There are already geostationary satellites providing this type of services, but at a prohibitive cost for many end-users. Existing satellites generally obit at an altitude of some 36,000 kilometres (22,000 miles) above Earth, weigh in at a hefty four to six tonnes each, and take much longer to bounce a signal back to Earth—about 500 milliseconds to be exact, according to an O3b document.
"It is such a long delay that people speaking over a satellite link will shorten conversations, interactive web has an extremely poor experience and many web-based software programmes just won't function." Crucially, they will communicate with Earth four times faster, said the company, and six would be enough to assure permanent coverage. "O3b's prices will be 30 — 50 percent less than traditional satellite services," said the document. ... Launch company Arianespace, which will put the satellites in orbit, said the O3b constellation will combine "the global reach of satellite coverage with the speed of a fiber-optic network." ... The next four satellites will be launched within weeks, according to Arianespace, and a final four "backup" orbiters early next year.'"

Such objects have no "weight", because weight is defined as, F=mg, a force F exerted by an object with mass m in a gravity field g, resting on a surface preventing the object from falling freely.
The mass of an object is thus independent of gravity, but it's "weight" is just an artifact impose

The COMMStellation network would relieve the strain by providing much-needed “backhaul” capacity to mobile networks around the world.
Someone familiar with this needs to clarify - exactly - how a high-latency and unreliable (compared to fiber) network could be considered backhaul. They claim data rates of 12 Gbps per satellite, but what type of data do they intend to carry? Do they expect smartphones to be manufactured with satellite modems? Or is it common in other parts of the world to build an HSPA+/LTE tower fed by T1's?
Call me skeptical, but both of these projects just seem to be round peg/square hole. A much more rel

Backhaul is probably exagerated, but the idea behind sats is that, if you manage to deploy them all, then their worldwide coverage allows you to reach way more customers than just 'your rural area'.
Indeed in O3B the B is for "billions", and these billions are not only "our other, poorer brothers" -they are actual billions of customers. Billions like in $Bn...
So, yes, having a space constellation is more efficient than just deploying lots of fibers locally, at least financially.

Given that you only need to get about 50km outside of the cities and main highways in Australia before you're completely screwed for Cable or DSL internet access, I'm rather glad they are providing satellite coverage to Australia. Anything to shove it up Telstra's arse and stop them charging over-the-top prices for shitty satellite connections with measly 5GB/month caps. Fuck you, Telstra!

The private investors are just the public face of this venture.
Their accounts receivables are insured against loss by the French government. This is a way for the French government to partially subsidize its own aerospace industry (in this case, the satellites are made by a French and an Italian joint effort), and at the same it's a way to control which war lords/governments in Congo, Ivory Coast, Mali, or Syria get free satellite internet access, and which war lords/governments in those parts of the world do not.
In other words, this infrastructure is a way to buy yourself some influence in those parts of the world (where French influence has been slowly shrinking otherwise).

Let's not exagerate.
French government indeed probably helped its industry through an export insurance scheme that somehow, in certain conditions, will allow Thales (the sat builder) not to die if the exchange rate become very wrong -but that's all they did, and the US are doing exactly the same now (they just started this kind of change insurance trick after France)
So, "yes and no": yes French gov.t (like now the US) found a way to insure export change rates, which helped Thales winning the O3B contract her

In generally accepted technical use (at least around where I live), a number in the form of 500 with no further info usually means "any x for 499.5<x<500.5". They probably should have said "half a second". The absolute lower limit is about a quarter of a second (due to the speed of light in vacuum and the altitude of geostationary satellites), but there are obviously some delays dictated by the design of the onboard systems (packet switching costs).

I don't know where you are getting your numbers from but europasat in the UK lists offers for sattelite internet on a pay as you go basis for £7 per gigabyte and you can get a lower cost per gigabyte by committing to a certain number of gigabytes per month. That seems to be in the same ballpark as cellular services.
Maratime and mobile sattelite internet services are far more expensive but afaict they are still not anywhere near the prices you give.
