Iridium Pushes Ahead Satellite Project

oxide7 writes "Iridium (IRDM) continues its push into the market for satellite data and telemetry services, as it announced the company that would build its second generation of satellites. Iridium's old network of 66 satellites was designed for voice calls; the new satellites will also be able to handle data more efficiently, and include cameras as well. The company also plans to share the satellite platforms with some scientists for use in studying the Earth."

But since the DoD contracts are already pretty saturated (seriously, does the military need a contract for more than 20k users?), the customer growth would have to come from the commercial or consumer sector.

      The problem is that Iridium data is a joke. 2400bps raw symbol rate, and you get even less than that, plus the handoffs can be touchy as one satellite passes over the horizon and another eeks into view. Inmarsat3 does 56kbps, and BGAN can go up into the hundreds of kbps.

      Iridium does have a latency advantage though, especially in mobile-to-mobile applications. It is, as you noted, suitable for low power or small form factor solutions as well, since Inmarsat needs an antenna the size of a large dinner plate while Iridium can get by with a slightly oversized cell phone aerial. Additionally, unless you buy a bulky mobile antenna, Inmarsat requires you to carefully point the antenna before you can use it, Iridium is happy as long as it is pointed vaguely up.

      If you need to transmit very small amounts of data in a small form factor, then Iridium is for you, but that is a decidedly niche market, especially when you start to consider the per-bit costs.

      Also, Iridium has better coverage (as in, full globe). GlobalStar actually has deadspots in their coverage because of their design. Also, one of Iridium's biggest customers is the US military - because of this global coverage. Inmarsat's great for fixed operations, but if you want an emergency telephone, the Iridium ones tend to be easier with their "see sky, point antenna at sky, make call" operation (i.e., no aiming). Dead spots is an issue - even if it's only 1% of the world that's not covered, you'll be the one needing to make a emergency call in that 1%.

      (FYI - an Iridium satellite is an orbiting cell tower capable of switching calls between satellite to ground, ground to satellite, and satellite to satellite. GlobalStar's architecture is "antenna up high" - you uplink to GlobalStar satellite which relays it to a ground station where the actual switching occurs. It's cheaper, but there are dead spots because a satellite might not be able to see a ground station - Iridium passes the call to another satellite in this case that might be able to see the ground, or routes the call onward again).

      Also, those SPOT devices use GlobalStar to relay your GPS coordinates to the ground station - very popular amongst hikers, pilots and other people where they may have issues getting continuous cell coverage.

      The Iridium satellites do not cause a noticeable problem for astronomers. They are a tiny portion of all satellites (and not significantly worse than any others), all of which together do not pose a problem. Do satellites occasionally show up in images? Sure. We deal with it - pretty easily, too. The lights in your driveway are a bigger concern.
      And sure, more space observatories would be nice (and yes, lunar would be great), but (for now, at least) they are prohibitively expensive, and often unnecessary - if you can get your data from a ground based telescope, why tack on a billion dollars and a new set of limitations? AO does wonderful things.

    When they first rolled out their service their business plan depended on the fact it would eventualy be as pervasive as cellular phones and that sure worked out fine.

    You have to keep in mind that when planning started for these services (and Iridium wasn't the only one) in the mid 1990's, it wasn't at all clear that cell phone services would expand as fast and penetrate as deeply as they ended up doing. Back then, cell phones were high tech toys with coverage largely limited to major urban areas.
     
    As an aside, one thing few people realize is that the roots of the current commercial space 'boom' lie in that era. It was widely believed that there would be multiple satellite providers, and that with each satellite network requiring between fifty and a hundred birds, that there would be a large number of launches both for initial provisioning and ongoing replacement. In the eyes of the alt.space community that meant an opportunity for a large market and a big chance to undercut the 'big boys'. They believed that by purchasing launches the satellite providers would end up underwriting the development of the boosters, providing a shortcut to commercial manned space.

      Iridium was planned in the late 80s, when cell phones were exotic and rare. It expected to cover the 90% of the world that didn't have cell service, to act as a pay-telephone in remote villages, etc.

      It took 10 years to get the system up to a marketable state (it wasn't late; that was the schedule to design, build, test, and deploy the dozens of satellites, multiple ground stations, and multiple brands of handsets). By that time a vast majority of the anticipated market was served by cellphones and by higher-data rate satellite services, but Iridium's technical specs and market anticipation barely moved.

      Except for that 2.4kbps data rate, the system was technologically wondrous when it went live. But hardly anyone needed it any more, especially at the prices it had to charge to break even. It nearly killed Motorola, leading to the closure or sale of many of its businesses, including Iridium.

      So a $5 billion project was sold for $50 or $150 million, or whatever it was. A much easier break-even point to reach, for sure.

      And Motorola went on to launch the Razor, resurrect itself, and change cell phones anyway.

    That assumes there are no capacity restrictions. While I can't say for certain I suspect their pricing is due to technical limitations of the satellites.

If they are capacity limited (and I'm just hypothesizing that they are) almost the worst thing that could happen to them would be to get too many customers. Too much business too quickly can kill a company almost as effectively as not enough business.
