Satellite Spotters Make Government Uneasy

An anonymous reader found an interesting little story about satellite spotters and how, not surprisingly, their painstakingly methodical hobby doesn't exactly make gazillion dollar government agencies all that excited. Of course the article raises the very obvious point that if a guy with a pair of binoculars in his back yard can spot a satellite, so can the Chinese government.

      It's worse than that. Visible light isn't the problem, it's self emission of long wave infrared (LWIR) radiation. The background of space is very cold (a few K above absolute zero), so anything with any significant temperature contrasts very nicely. In theory it might be possible to cool the front side of the (notionally black) satellite to near zero deg K, but in practice that'd take prohibitive energy, since that nice black surface would absorb a whole lot of solar energy when exposed (~1/2 the time).

      So, civilian satellite spotters aren't the real problem, it's inimical militaries with LWIR telescopes...and there's pretty well nothing to be done about it.

      You get two satellites up there for the price of one, in essence, while disguising that one of 'em -is- a satellite, rather than just another discarded upper stage of a rocket.

      There are several advantages of this method of doing things:

      Number 1, you don't have to hide that it's up there at all. You can have everyone looking at it, but unless they spot the camera aperture, they're not likely to guess that it's being used for anything at all.

      Number 2, because you don't have to worry about hiding it, you've got a bit more elbowroom--you don't have to fit it into a tiny form factor, or worry too much about hardening the electronics against excessive heat buildup. Wrap the thing in gold foil if you like, as nobody's going to see it inside the booster's skin. If you're clever, you can run the antenna out one of the ends without anything being too obvious.

      Number 3, the cost of putting it up is lessened, because the company that's buying the shot will not necessarily even know that there's a hanger-on sitting below their TV satellite or whatnot.

      Number 3b, because of the reduced cost, you can put more of 'em up and get better coverage.

      Number 4, not only will the booster help hide the satellite from prying eyes visually, it will also hide it on infrared wavelengths--because of course the booster will be a bit warm; it's got a lot of mass and a fairly large size to pick up radiation with during the day.

      Sure, there are some drawbacks--it may require some work to fit the components in around existing fuel tanks and the like--but it's doable, it's doable with today's technology, it's doable for less money than many other solutions, and, frankly, given my track record for ingenious ideas, it's probably already being done by at least three governments.

They don't just hover over interesting parts of the world, they orbit the globe while the earth spins beneath them. And interesting parts of the world don't magically appear beneath their tracks. To aim them means to change their orbit so they fly over the parts that you currently find interesting.

      Rocket boosters are mostly uninteresting because they do not have to be aimed -- they are transferred once to a parking orbit, and there they stay until decay drops them back to earth.

      But if a rocket booster were to change orbits more than twice, it would suddenly become a very interesting rocket booster.

      Other than a handful of satellites with wide public visibility, payloads are not identified. Amateurs label them as they spot them, but civilians don't know for sure if satellite USA-193 is a spy satellite, military satellite, or whatever.

  25. Orbit follows function by mbone · · Score: 3, Insightful

    Satellites are classified by orbits, and orbital maneuvering, more than by anything else (assuming you don't have direct knowledge of their mission). Different satellites have different orbits for a reason, to support their mission, and their orbits thus provide information about their missions. GPS satellites are in high 12 hour orbits, comm sats are in even higher, 24 hour, orbits, weather satellites are in sun-synchronous polar orbits, etc.

    An example : if you have an orbit that passes over Baghdad, big deal, they all will do that sooner or later. If you have one that passes over Baghdad early to mid-morning, when the shadows are nice and long (generally regarded as the best time for surface photography), you may have something. If you have an object whose orbit is continually tweaked to keep passing over Baghdad during mid-morning every few days, and that also happens to be at the perigee of the orbit, then you almost certainly have something. If you look at where it passes over during later-afternoon on other orbits, you may start to gain insight into what other targets are of interest.

    You can bet that every serious intelligence service on the planet does this. Amateurs have been doing it since the 1950's, so this is old, old news.
