Iridium Files for Bankruptcy 102
MadShark writes "I found this article on Excite about Iridium LLC filing for bankruptcy after defaulting on 1.5 billion dollars in loans. But don't be too hasty about throwing out that handset. The article also says, "Motorola said it would continue full operational support for Iridium and all current and future
subscribers during the company's reorganization. It said it would continue to invest in the
technology and to develop the next generation of Iridium products."

Meaning the Telco's couldn't let someone call from USA to England over sat without making a long distance. And the switching capabilities are't very good.
Also, no Sat to Sat switching either.

End of life for this class of satellite is not when it re-enters, but when the expected reliability of the electronics, battery, and solar array fall below a certain desired level. Typically, some amount of propellant is reserved to do a deorbit burn to take the satellite out of its position, and cause it to fall back into the atmosphere and burn up over a long (25 years?) period.

GEO sats have drawbacks too. Most importantly, it takes a fsck-load of propellant to get out there.
So, you have hundreds of high speed satellites wizzing around requiring a load of fuel to keep on track. (And when the fuel runs out, the satellite is dead and needs replacing)
A GEO satellite requires an order of magnitude or two more propellant than a Low Earth Orbit Sat. Frequency of replacement of the satellite is driven less by running out of fuel than by the life of the electronics. Also, GEO satellites do _not_ just "stay put". The amount of fuel needed to keep a GEO sat from drifting across the sky is incredibly higher than that needed by a LEO sat to stay on track.
Another point - GEO satellites require the largest launch vehicles to get up there. LEO sats can be launched on just about anything, and in a constellation like this one, several sats can be launched by a single launch vehicle.
And if a single one goes wrong, the chances of it colliding with another are remarkably high, thus wiping out the whole lot in that orbit. (Well, risiking doing so...)
Hmm... FUD. While it is within the realm of possibility, and certainly taken into account during the design, these things are spaced so far apart that collision just isn't going to be that much of a danger.
Some issues you didn't mention that I find to be much bigger... Unlike GEO, these sats are up near the radiation belts (which is why electronics life is the limiting factor for the system.) And simply _producing_ the quantity of satellites these constellations need is a logistical trick that aerospace companies are not used to. And a constellation of hundreds of satellites are really, really expensive.
Like anything else in life, there's trades. GEO sats are good for some applications, LEO constellations good for others. Personally, I wonder if constellation systems can provide all that much more than ground based systems. That said, I do think things like Iridium are cool, and I hope some of the follow-on systems have a chance to get off the ground. I'm sure there's a niche to be found someplace, and the idea of being telecommute from anywhere in the world (i.e., travel the globe without ever taking a day off work) is just too cool. ;-)

Bloody stupid idea (Score:1)
When anyone in the inmarsat offices mentioned iridium everyone burst out giggling. Low Earth Orbit is a JOKE. Do you have any idea how FAST those things have to go to stay up at such a low altitude? And because the go so fast they are only overhead for a short length of time, so you need so damn many. So, you have hundreds of high speed satellites wizzing around requiring a load of fuel to keep on track. (And when the fuel runs out, the satellite is dead and needs replacing)
And if a single one goes wrong, the chances of it colliding with another are remarkably high, thus wiping out the whole lot in that orbit. (Well, risiking doing so...)
It's a joke. And of course since a given satellite is overhead for so little time, the swignalling is far more complex, requiring all the land stations to be more failure prone blah blah blah.
Sure, Inmarsat have bugger all bandwidth left, but at least you can get a signal from pretty much anywhere but the poles.

There are serious technical problems with using a analog modem over a satelite telephone link. The compression and noise supression algorithms assume a voice call (certain frequencies, relatively long pauses between words). Using a regular analog modem would never work well and might not work at all. They could, however, develop a digital modem to directly interface with the digital satellite link but the bit rates would never be that high.
It probably makes sense for data customers to wait for the Teledesic system which is optimized for data traffic.

If Iridium had launched five years ago, maybe the technology need would have been there, but the cost would have been even more prohibitive. Iridium is living proof that hype doesn't pay the bills.

The reason they're filing for bankruptcy is because they've gotten less than 10% of their planned number of subscribers. The reasons for this are varied, but they include greater competition from PCS and cellular phones, and the fact that the phones haven't been working well indoors.

US government Props Up Iridium [theregister.co.uk]

excerpt:
The US government continued its attempt to prop up troubled satellite-based cellphone company Iridium, yesterday. The Department of State signed a $1.4 million cheque for 1000 Motorola-made Iridium handsets.
The US government is rather keen on Iridium -- it bought another huge pile of phones back in June. It has its own gateway into the network, and according to the release issued about yesterday's purchase, "other US government agencies" plan to make use of it.

Phones not working well indoors is by design.
Sure MOT got most of the Iridium money, but much of it was money spent buying parts or doing development, so all they get is a bunch of legacy code. And the experience of negotiating a few launch contracts.
2 year lifetime is something that I don't really buy; they're probably saying that to make sure they don't get sued if their satellites went down too fast. Of course, there are lots of things that can fail on satellites, so you can never be sure.
Those of you who hope that Teledesic will be nice, fast, sanely priced, and well designed, remember who's the prime contractor =)

Hard to trace, perhaps, but VERY easy to tap. Just point an antenna at every satellite and you've got 'em all. What signal goes up must come down - at least while all the handsets are on the planet's surface. Tapping regular cellular, meanwhle, needs a receiver in each cell of interest unless you can tap the network feeding the base stations.
And you might be able to get some location info from the satellites, too.
