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."
A slashvertisement for *who*? Raise you hand if you can afford a satellite!
I really hope they solved the 3 issues with their previous attempt: 1. Cost per minute of usage 2. Need for huge antennas (adds to bulk/weight) 3. Massive battery required (makes the phone bulky/heavier).
I hope they will be less reflective. Their flares cause troubles to astronomers.
Iridium are the best duplex LEO network (better for low power applications than GEO) and the only serious competition to Inmarsat. Inmarsat would not have made nearly as much progress if they had no decent competition - GlobalStar are simplex and Orbcomm are as abysmally useless are always.
Ever heard of GeoEye?

Actually You may be surprised. Yes it will not be you average point and shoot but these are in a pretty low orbit. You get a professional medium format body with a good 40 MP CCD for around$10,000 combine sensor that with good optics and space rate it and the entire package would probably run under $100,000. Of course you may want IR as well as visual range but the overall cost will still be manageable.
How good can you get? I am not sure. Probably not as good as the best Google earth pictures but maybe two zoom levels higher. To be honest yes they are all guesses because I am not an expert on photography.
Is to the business case. Yes military already use commercial imaging all the time. With this system the delay between and event and getting imagery would be extremely short.
Think about Haiti or the other natural disasters. Pretty good high resolution imagery could be available in under an hour in almost any case.
Weather monitoring is another option. We could bet much better coverage of the polar regions with these.
So yea I can see some real use
See my blog http://ilovecookes.blogspot.com/ for light hearted technical information.
You probably do not realize that the images Google Earth uses are largely collected by private satellites?
GeoEye is one of them, for instance. DigitalGlobe operates several as well.
As for hefty infrastructure on the ground; there are companies selling ground station services. I work for one of them and it doesn't cost you much to buy a time slot to communicate with your satellite. Heck, we offer the complete process, you only need TCP/IP (or ISDN if you are conservative). The launch does not have to be too expensive if you piggyback on the Indian launchers. But of course, you have to build it first :)
And Iridium has a decent ground network for something like this (we actually happen to host some of it too).
