Iridium Saved?
The Mutant writes "Some good information here - the proposed purchaser will pay 900,000 US a month while the business plan is being reviewed - is that what ist costs MoTo to run Iridium? Also, they apparently will get Iridium for about two cents on the dollar.
How could not you make money with a deal like that? Even if you were NOT planning on replacing satellites as they deorbit due to age.

I was hoping for the fireworks show... when they blowed up real good and re-entered the atmosphere...

unless they make they phones smaller and easier to use i dont think it will be a success
First post?
What we need is a public infrastructure effort to support Iridium and similar systems on a global scale. Some sort of a public consortium for effectively enabling communication for the masses...or am I dreaming?
I'd buy that for a dollar.
'Course...that'd only get me about 50 bucks worth of Iridium, but that should be enough for one of them orbity thingys, right?

What commercial potential does Iridium have? Their phones are bulky, the service is unreliable, the data transmission speed would be rediculously low. When the service was cancelled, Iridium had under 100,000 subscribers--not even enough to cover operating costs let alone the cost of the network itself. Even if the cost-per-minute is reduced so as to virtually eliminate sat-phones from the marketplace, how many subscribers could the get? It seems like more good money being thrown after bad.

It seems to me that the biggest value in Iridium isn't the network, it's the technical expertice of their engineers, who could be called upon to design the next generation of global orbital communications networking... by a company with sufficient resources.
Still, I'm not convinced that's the way to go. Ground based communication is getting some pretty high penetration, and until the tech gets good enough to compete with ground based, affordably, there's no market. On the other hand, if they managed to make Iridium work as well as it did in the first place, those techs are probably the kind of wiz needed to get broadband wireless up and running for a ground based system. I mean, wireless is close to replacing land line phones in places like college campuses and the like... can you imagine Iridium tech converted to wireless WAN?
-- Still waiting for the Nike endorsement
I suspect that Motorola may have missed some of the target markets for Iridium. They seemed to go after the worold wide roaming cell phone market; given the bicks the phones are hurts this effort. Perhaps they should have looked at markets such as small ships, outback overland truck traffic, and trains. These users could accept equipment that resembled current two-way radios to get mounted onto the vehicle. The cost is in the same range as alternative for those markets. From what I've heard, Iridium doesn't handle data traffic too well. Does anyone know if this is true ?
Despite technical problems some astronomers have with these sats, the very thought of burning over sixty working satellites without really using them just feels wrong. Kudos Castle Harlan!
BTW, does anyone have a web site for Castle Harlan?
Democracy is two wolves and a lamb voting on what to have for lunch. Liberty is a well-armed lamb contesting the vote.
Irideum has already put in place a procedure for crashing and burning the entire fleat of Satalites shuld they not recive funding to keap them up.
Imagine a Mining company that as it's last gesture before going bancrupt initiates an environmental restoration.
This is responsible behavior and despite all the other things wrong with Iridium, this makes me simpathetic. All the best to them.

I was watching some brainrot or other on the tele, probably CNN, and the discussion topic was portable phones, and why Motorola wasn't doing as well as they thought they would. The answer was, primarily, cash. How can you not make money on Iridium? Lack of market. I might buy a satphone if I eventually buy that sailboat and want to be able to telecommute from the sea. Those who find themselves out and about and in unreliable phone country might want one. The market is relatively small, compared to the cellular/pcs/digital market, whereby most people in a reasonably sized urban area have reliable service. Consider the cost of the system, as well. Sure, those who need it can afford it, but as a measure of how much revenue that will generate, the outlook isn't great. So, factors: What is the total cost to OPERATE (not purchase) the system, compared to the amount of revenue which can be generated? What is the total start-up cost for the average customer, and is that low enough to allow broad entry? How does Iridium rate when put next to any other phone carrier, in terms of cost and benefit? I said all that to say this: Most mobile customers aren't willing to pay a premuim rate for more mobility. Of course, I'm probably wrong. =) All remains to be seen.
-- build a man a fire and he'll be warm all day. set a man on fire and he'll be warm for the rest of his life.
Sure, if they buy Iridium they'll get a functioning satellite network for pennies on the dollar. And it can be run pretty cheaply, I'm sure - Motorola is still spending money to run it until they all get augered in, so it can't be too bad. But even if they can rescue it on the cheap and start suddenly selling the sat phones again for low prices, there's still one big problem.
Iridium has, essentially, an expiration date.
These satellites are all in LEO, and only have a lifespan of about 5-7 years or so before they flame out. The earliest launched satellites are already approaching their end of life, and even buying the network on the cheap doesn't do anything to relieve the replacement cost. Just because the current space assets are cheap doesn't get you out of the cost of building the network all over again over the next decade. It'll still cost billions to put 66 more of these in orbit.
Can they get the critical mass of users needed to make replacement viable before the capital drain gets too bad? Somebody must believe that's the case, but I really doubt it.

As impossible as it sounds to people who write .com business plans, it actually is possible to not make money if you're running a business wherein you're spending more money than people are giving you for your product or service.
Since they're spending close to $1m a month to keep it in the air, advanced quantum calculations reveal that it is possible for them to not make money if they don't generate at least that much revenue. For example, because most people spend most of their time in relatively urban areas, where the cellular infrastructure has been built up to ubiquitous proportions, and satellite phones don't work so well due to line-of-sight problems, multipath interference, etc.
Ok, so we know these phones ar big. But, everyone and their dog has a laptop these days, and iridium is looking for a way to keep itself "afloat" so to speak. What if they make satelite phone modems that attach to your laptop? I mean, cellular phones don't always work overseas and in planes, where internet access is wanted for not only entertainment on flights, but for people doing work on their spare time that require connectivity at home. As i see it, they went into the wrong market. Strike a deal with some laptop companies, have them ship with your modems and internet plans, and you've got it made.
Any transmission with a roundtrip distance of over 140,000 km is gonna suck - you guarantee yourself almost 500ms of lag before you even deal with the Internet infrastructure.
Maybe Iridium is ok for phones (since we do so much of that already), but I doubt it will ever be practical to repurpose it for anything other than basic communications, unless everyone can have megabytes of bandwidth per second, or are willing to accept really crappy Internet performance.

fat lenny's gonna lick your brain today.
Okay. Here's a hint. Don't do your reseach from 1961 Popular Electronics magazine predictions of what things would be like by now.
. In any event, the satellite is actually pretty cheap - about $10-20k to put it into orbit with a nice transmitter and a few solar cells plus the mandatory stuff you'd find in a comm sat.Sure. And in 1961, they thought we'd have flying cars by now. And there'd be martian colonies, let alone lunar colonies.
I hate to break it to you, but most of the time, the $15-20k figure is *per pound* of launch weight. That's not to build the satellite - that's just to put it into orbit. Russian Soyuz rockets run along the cheap end, primarily because they're statistically more likely to blow up (and destroy your multi-million dollar satellite).
For a comms satellite, you need a receiver and a transmitter, all powered by a solar cell. Such an arrangement is actually called a "transponder", since it just basically mirrors back a given signal on a different frequency and orientation.
Even for the low-band microwave C and Ku band satellite TV systems (mass produced and therefore quite cheap in comparison), receivers are not inexpensive. (And I mean the LNA/downconverter in the feedhorn, not the the set-top box.)
Simply to run any device at frequencies as high as are required for use like this, requires tremendously tight mechanical and eletronic tolerances be enforced. This costs a lot, both in machine tools, skilled employees, and also in a reduced product yield rate.
For sake of example, I often buy magnetrons for work. These aren't microwave oven magnetrons (which aren't for communications and therefore don't have to be too precise). These are radar magnetrons, running in the 12GHz band. RMS power through them is 7 watts. And they operate at normal temperatures (-40c to +70c). And they're damned expensive. Some of the EEV and JRC models I use run in the range of $4,000 - $6,000 each.
Now, consider that most modern satellite transponders run 12W transmit power. That means a bigger magnetron than my $5,000 tubes. And there's another problem: a magnetron is a tube with a magnet around it. Tubes aren't reliable or compact enough to launch, and magnets don't like temperature extremes. We don't use high-powered solid-state magnetron-equivalents in our radar systems because they're just *way* too expensive. Even a small solid-state Gunn diode for a radar speed gun can set you back $5,000 - and that's not even 1/1000th of the power you'd need.
In short, what I'm getting at, I think, is that there's no way in hell you're ever going to find a transmitting device for one transponder, let alone the rest of the transponder, let alone every other part of the satellite, let alone... for anything in the price range you're quoting.
If you really want a Satellite, I have one. It's a chrome emblem off a 1960s Plymouth. It says "Satellite", in letters about 1" tall. And ya know what, just for irony's sake, I'll *give* it to you if you promise to pay to put the thing into geosynchronous orbit.
But you couldn't even get that Satellite into orbit for the money you're talking about.
Fire and Meat. Yummy.
I applaud all those creative technical minds trying to come up with interesting and useful applications for this networks, but without hard info, we're just pissing in the wind and blowing hot air.
There's a fairly recent and detailed IEEE report on the Iridium network
Here's a chart of competing systems that are up, or will be up soon
Here's a fairly complete description of several current satellite telephone systems with info on frequency allocations, ground stations, and other important network details [has a chapter on iridium]
Here's a article in Test System News testing Iridium handsets and network for real world performance
More to come....
If you can go to bed, knowing you did a valuable thing today, you're very lucky. If you can't... it's not bedtime
Did anybody actually read the linked artical @ CNET? Did anybody besides me notice that the writer placed links on certain promiscuious words? (Climax, Withdrew, etc...). Sorry this is a little off-topic, but it is somewhat funny to think about what was going through the writers mind...
Skiers and Riders -- http://www.snowjournal.com
Soon, on a DVB receiver card near you... Watch this spot...
Well presumably they could shut down such a transmission by using the laws of the country where the ground station is, but we could always claim it was just a test pattern...
Say no to software patents.
In April 1999, the Defense Department signed a $219M contract with Iridium for service, equipment, etc. I don't know thye exact terms (duration, etc.) but it had to be at least a year, and couldn't take effect much before June 1999. [Here's a link]
The DoD was involved from the beginning, sitting in on the design and planning for the network, and reportedly constructing a $100M DoD-only ground station.
If they stay on board, than the numbers for this new iridium venture could change. In the short term, the DoD money alone (assuming it was sensibly structures as monthly payments) could cover maintanance, taking much of the strain off the business plan, and allowing otherwise impractical applications to be profitable.
If you can go to bed, knowing you did a valuable thing today, you're very lucky. If you can't... it's not bedtime
Even if someone got rid of all of Iridium's debt and gave the constellation to you, you'd still lose money on the O&M (operations and maintenence) agreement with Motorola. MOT's been running the constellation free of charge so that IRID could attempt to make debt payments, but that didn't quite work, but even without debt payments, income < O&M costs, so.... you'd have to get a better O&M deal with MOT to even break even.
Basically what running the constellation means is making sure that the satellites don't fall out of their orbits due to perturbations caused by the sun and moon, and the fact that the Earth is not a perfect sphere. Also there's network maintence costs, and billing costs.
When Iridium finally hit the market, enabling the purchase of a clunky handset for $3'500 enabling phone calls for 7 bucks a pop, err! a minute they left out the most important entity: The business traveller.
A lot of business travellers don't reside in the US and Korea. The US still has the problem of an 80% ananlog network, which is notoriously complicated, calls are paid by the receiver (partially) and if you really depend on your phone, Iridium might be an, allas expensive option. Why Korea didn't go for GSM escapes me.
The rest of the business world relies on GSM. Now with GSM I can exit the plane in Paris switch on my phone and place & receive calls for 40 cents a minute after thirty seconds. The same applies for Australian cities, the Indonisian djungle or a Bangkok surburb. Oh, yeah: The sicilian mountain village also provides excellent reception. Oh and all this on my neat new Nokia 8210, curtesy of Swisscom.
Those few polar scientists, astronauts and Y2K business that pay the price just don't build up critical mass.
Ergo an expensive, and outdated businessplan, ignoring not only technical development, but also half of the civilized world and no fashionable handsets. Iridium was doomed and who cares Thank you for your attention...ich bin der musikant

Deep breath
But all (I think) Iridium phones take SIM-Cards and roam on GSM networks... the point is to have a system that works when you're out of range of GSM networks. Of course, you have to be outdoors and all that, but...
So GSM doesn't cover oceans and such, and Iridium could have made a great market out of that, but I haven't seen that side of it's marketing. (In fact, given the alternatives in that space, Iridium is small and more convienient).
140.000km round-trip would be for geosynchronous satelittes (4 * 36000). But these are low orbitting satelites, who are at an altitude more like 780km. That would make your round-trip 3000km, which is quite manageable (10ms).
Say no to software patents.
I remember when I read about Iridium, a couple of years ago in a WIRED. The funny thing was, it seemed like a good concept, but it didn't seem as if it was going to work. It seemed like one of those farfetched things that wasn't going to happen.
What they did, is they set a huge goal for themselves, and took all the right steps to form this company. I remember reading how they had a whole democratic heirarchy throughout the world, for their business. Yet, the only problem is, you need a working product to make money.
You have to let huge technological acheivements evolve on their own. That isn't to say, just everyone sit back and expect things to invent themselves, I'm just saying, things come about when your not looking for them.
"Success comes to those who are too busy to look for it."
Someone asked about bandwidth: it's about 4.3k/s per phone, but the technology allows you gang several connections for greater bandwidth.
Someone else was griping about the size of the handheld units: the most recent phone is about the size of a sony cordless phone that you might find in any household. Remember that for satphone communications you are limited to a certain length for the antenna, and require to certain gain to be able to communicate with the satellite.
Others have mentioned that the satellites will deorbit in the next year/5 years: this is just a misnomer, some of the satellites would need to be replaced, but many of them can be maintained beyond their specified lifespan.
As far as making a profit, the Castle Harlan is just the finance company, and they acting as a broker for another company that was set up specifically to take over the Iridium project. The largest projected source of revenue is government contracts (duh, who else needs to call anywhere, any time?), this alone should allow them the $1 million/month operating costs, and profit enough for future maintenance. Keep in mind that the deal is far more complex than the watered down version you see on CNET.
Last but not least, remember the story of chicken little...
I for one would love to see Iridium stick around for a while, and I wish them the best of luck.

There have been a lot of questions about the On-Board Processing available on Iridium. This article offers some information about Iridium's on-board Motorola hardware, compared to other systems, and discusses the networking structure (ground and orbital)
There's more info and actual data in an article called Supporting ATM on a Low-Earth Orbit Sattelite System covering the ATM switching network in iridium, including goodies like signal strengths in various ground settings and conditions, traffic capacities, and RF restrictions internationally.

1) Equip all the satellites with death lasers.
2) Extort billions from every civilized country at death laser point.
3) When the secret agents show up to foil your plan and you capture them, shoot them in the head immediately and personally. Do not gloat about your plans. Do not leave them suspended over a pool of ravenous pirhanas. Do not trust some henchman to do the job for you. Do not show them the large and prominent satellite self-destruct button.
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
Having a bunch of satelites whizzing round, broadcasting near to scientifically very interesting regions of the microwave region never made any sense. We pollute the sky with enough radiation that astronomy is difficult enough as it is. If an alien were looking at our planet they would most likely think our atmosphere predominantly contained sodium, since so much of the planet is lit with it.
From a Motorola white paper:
Designing Space Systems for Manufacturability
It looks like the cost is ~$19.8k/kg for the iridium satellites. I believe this includes both manufacturing and launch costs, though the paper is not so specific. However, remember that because they were manufacturing 66 identical satellites, they were able to greatly reduce the per satellite cost. The same paper lists a cost of ~$66k/kg for a single conventional satellite. Also, note that in building iridium Motorola set a number of industry records for Manufacturing and Deployment of Satellites (see motorola press release). Somehow, I don't think any inexperienced yahoo is going to rival this accomplishment!

This is very sad news indeed. I am very sorry that Iridium satelites may not be destroyed after all. These satelites are astronomers' worst nightmare, polluting in forbidden radio ranges, interfering with cold hydrogen frequencies (21.1cm). The world astronomer community was cheering to find out that Iridium satelites were supposed to be brought down and now this....

Buy? Why? Let Iridium Die
(sequel to "Bye, Bye, Miss Iridium Pie")
Long, long time ago I can still remember how their tech plan made me wince
And I knew if I had their cash
That I could buy the monster stash
It'd take to grasp all that's happened since.
But Motorola made me shiver
With every mission they delivered
Satellites in orbit,
I couldn't take one more bit.
I couldn't look, afraid I'd find
Wall Street had lost its bloody mind.
Something so awkwardly designed... I knew Iridium'd die.
But now it's:

With just millions we'll get billions, though it's pie in the sky
The good ideas must've all gone dry
So the VC's and the bankers all buy
So the VC's and the bankers all buy
Do they know the specs we love?
Or do they have faith in stuff above
'Cuz the tech just say it's true?
Oh what a splendid fit they'd throw,
if they understood L.E.O.
And how the orbit's bound to crash real soon.
Do they know the facts and take a stand?
Or is it just an Accounting scam?
Another tax write-off?
A business 'loss' (*cough cough*)
I'm just an aging hardware hack,
with a calculator, and not smoking crack
So they had me rolling on my back
The day they shouted "Buy!"
And they were singing:

Why spend millions to get billions of just pie in the sky?
The good ideas must've all gone dry
So the VC's and the bankers all buy
So the VC's and the bankers all buy
Well for ten years they've been slick
And the business plan that made me sick
Is not what it's supposed to be.
When investors sang in the court of law
In a place where truth brings on awe
In a voice that sounds like Craig McCaw.
Debating "Should we just bring them down?"
(Scam websites sprouting all around)
The verdict was returned:
The system soon would burn!
And when Slashdot had a thread on use,
the clueless all were running loose
(Even trolls aren't that obtuse!)
"Don't let Iridium die!"
And I'm still singing:
"Buy? Why? Let Iridium die!"
Why spend millions to get billions that's just pie in the sky?
The good ideas must've all gone dry
So the VC's and the bankers all buy
So the VC's and the bankers all buy
Helter Skelter in the summer swelter.
The VC's offer last second shelter,
Fifty Mill and running costs
Until the plan is finally passed,
by a judge who must be smoking grass
What the heck, it's not like it's *his* cash
For months, we had sweet surcease
From addled threads and press release
Now I just want to cry.
This network just won't die!
Then Katz posts "can't you all see..."
(the tempers fly, as usually)
He compared it all to MP3... the way Iridium died.
We kept on screaming:
"Buy! Buy! The Iridium pie!"
Spend just millions to get billions though it's pie in the sky!
The good ideas must've all gone dry
So the VC's and the bankers all buy
So the VC's and the bankers all buy
Now don't get me wrong, I love space
It's a sanctified holy place
But here's our chance to start again
So let's get real, let's get smart.
Iridium soon will fall apart
And funding is this devil's only friend
So let's just watch the rockets flare,
the satellites plunge through the air.
While there still is time
(and rebuild it, right this time!)
As the flames all fall from the sky,
let's clap until we think we'll cry
Let's let Iridium die!
We should be singing:
"Buy? Why? Let Iridium die!"
Why spend millions to get billions that's just pie in the sky?
The good ideas must've all gone dry
So the VC's and the bankers all buy
So the VC's and the bankers all buy
I met a man who had a clue, and asked him what else we could do
But he just smiled and turned away.
I want to go up five hundred, miles, where I'd kept my tech dreams as a child,
But the man there said manned payloads wouldn't pay.
In the halls the techies sighed, the coders laughed, and the testers cried,
Not a word was spoken, the promises all were broken.
Like the other dreams they shot to hell, like anti-grav and FTL
and condos stationed at 5-L,
But they fund Iridium... why?
'Cuz they're still singing
"Buy! Buy! The Iridium pie!"
Spent just millions to get billions but it's pie in the sky
The good ideas must've all gone dry
So the VC's and the bankers all buy
So the VC's and the bankers all buy
If you can go to bed, knowing you did a valuable thing today, you're very lucky. If you can't... it's not bedtime
I'm sure there are plenty of radio astronomers who would love to see the Iridium constellation shut down for good.
RMS, in statistics, refers to root mean square: square the signal, take the mean, and take the square root.
Will I retire or break 10K?
If you run a mine/factory/mad scientist HQ, and you pollute the environment, and a disproportionate number of people in the area start dying of cancer, it's next to impossible to prove conclusively in a court of law that the pollution caused the cancer.
If, on the other hand, something that you put in orbit falls out of orbit, crashes into a building, and kills a number of people, the legal chain of causality is much shorter.
Granted, a company that's going bankrupt doesn't exactly have a lot to lose (assuming nobody buys it). But I believe that, if death and injury is involved, it's also possible to hold the company execs personally liable. So they have to have a "crash and burn" plan to cover their asses.

Our apologies. Obviously, we should have realized that you were planning to launch the satellites with your own hot air. Using parts that you had pulled from your ass.
I guess I'm just not a shrewd enough business man to see the potential

Why was my gay post moderated down?
-o I'm not monotheist; It's obvious I'm a queer. o-
Don't forget that motorola only has 25% of Iridium. The other 75% is held by a consortium of nationally-owned telcos that all have ground-to- satellite stations. At the price the buyers are getting the network for they may be able to make money from handling international calls that would ordinarily travel on land lines. The greatest part of the system's cost was for r+d. Building and launching replacement satellites is relatively cheap now that the design has been finalised. I worked on the electric wiring of the facility where the satellites were assembled and saw the process up close - they were pumping out completed satellites at a rate of one a week with a small crew.
If your'e not the Lead Dog, the view never changes . . .
Nothing. But while it'd be really cool to have a satellite orbiting the earth just for your amusement and ego-trip, it's not gonna happen unless you're Bill Gates. (I doubt Trump could afford to pull it off, for sake of cost analogy.)
I'm sure The Donald would love to have a big orbiting "T".
The great thing about this launch cost is that it makes organizations think more before they put something into orbit. And this cuts down on space debris, which is a growing hazard.
To maintain something in orbit, it has to be travelling at several thousand miles per hour. I forget what the exact bottom-end figure was, but it's very amazingly high. Since this is in (effectively) a vacuum, there's no friction to slow the orbiting object down, and therefore they can remain aloft for years before slowing to the point of impact. Consider the moon: it's a satellite, it orbits earth. If it weren't moving so damned fast (we see it as lunar cycles from earth), it wouldn't have the centrifugal force required to balance the pull of earth's gravity, and it would crash into us.
As a satellite encounters trace gases in space, the friction from contact with those trace gases will eventually slow it down to the point of getting pulled into the atmosphere and burning up. (Although SkyLab didn't completely burn up...)
Now, why is debris such a risk? Even worse than the small chances of the thing coming back and big chunks of hot metal raining down on a city, you have to consider what happens when one object impacts another one.
When you hit a telephone pole with a car, the force of impact is a function of the mass of the vehicle and its speed. A 4,000lb car at 100MPH will do a lot of damage to the telephone pole. (*What* telephone pole? All I see is a pile of toothpicks!)
Now, when a 40lb chunk of metal that fell off your homebrew satellite is orbiting at 10,000MPH and happens to hit the side of the newly-comleted International Space Station sometime in the future, you tell me what happens.
Putting protective shielding into everything up there would be nice, but it's really very expensive to do because of the costs in fuel and rocket size per pound of launch weight. And the bigger the rocket, the bigger the booster tanks, which means the bigger the explosion and the more scattered the orbiting debris will be when an O-ring pops a la Challenger.
So, to conclude this thesis, ain't no way you're gonna do it, and for the safety of space exploration and research, it's a damned good thing that every yahoo out there can't launch one off the back of his pickup truck.
Or for that matter, using commercial parts?Well, you could start collecting your fertilizer and ammonia now, but I think the FBI will get concerned about another Oklahoma City incident and will stop you before you could accumulate enough to get the Zippo that you're planning on using to ignite your engine into orbit.
