SpaceX Gets FCC License For 1 Million Satellite-Broadband User Terminals (arstechnica.com) 46

Posted by BeauHD from the UFOs-on-a-stick dept.
SpaceX has received government approval to deploy up to 1 million user terminals in the United States for its Starlink satellite-broadband constellation. Ars Technica reports: SpaceX asked the Federal Communications Commission for the license in February 2019, and the FCC announced its approval in a public notice last week. The FCC approval is for "a blanket license for the operation of up to 1,000,000 fixed earth stations that will communicate with [SpaceX's] non-geostationary orbit satellite system." The license is good for 15 years. As SpaceX's application said, the earth stations are "user terminals [that] employ advanced phased-array beam-forming and digital-processing technologies to make highly efficient use of Ku-band spectrum resources by supporting highly directive, steered antenna beams that track the system's low-Earth orbit satellites."

One million terminals would only cover a fraction of U.S. homes, but SpaceX isn't necessarily looking to sign up huge portions of the U.S. population. Musk said at the conference that Starlink will likely serve the "3 or 4 percent hardest-to-reach customers for telcos" and "people who simply have no connectivity right now, or the connectivity is really bad." Starlink won't have lots of customers in big cities like LA "because the bandwidth per cell is simply not high enough," he said.

        The coolest part of phased arrays is the "steerability" of the output. By shifting the phase of each element in the array slightly the effective power of the output is directed where you want it. Hence their land station's ability to transmit a signal to a moving satellite with a fixed element antenna. (link [wikipedia.org] from the same article.) Really cool stuff.

        I work with phased arrays for radio astronomy. Here's how I explain them to students.

        You've probably seen parabolic (dish-shaped) antennas like this [wikipedia.org] used for communicating with satellites. The parabolic shape focuses the incoming radio waves to a point in front of the dish, where there's a radio receiver that detects them.

        In a phased array, you have a flat surface with *lots* of radio receivers. Each of them detects the radio waves hitting its little patch of the surface. Then, you take the signals from

      • In addition to improving reception, a phased array antenna will allow the creation and aiming of a concentrated beam without moving parts.

        This would be immensely useful for communicating with fast moving satellites.

        A bit complicated, but it all boils down to Fourier.

        Only works for transmit though, i.e. from the ground towards the satellite. The receiver will need to either be extremely sensitive or have some way to concentrate the signal, i.e. a satellite dish.

        The main issue is going to be network congestion. Also remember to take anything that comes from a Musk company with a bucket of salt, e.g. "free supercharging for life" or "coast to coast demo in 2017".

        • Actually, due to a radio principle known as reciprocity, if you can send a focused beam with this antenna, you can also receive a focused beam with the antenna.

          As mentioned in one of the other comments, the phased array is made of lots of little antennas. Each antenna, in itself, is receiving a wide variety of signal and noise. Indeed, for any given antenna, the signal may be completely lost in the noise. But, if you add the signal from two antennas, and do a slight time offset between them, the signal
      • The antenna in the nose of the F-16 is similar. It's smaller, overall, and the individual elements are larger. But F-16 tech is decades older.

        The F-16 could track multiple airborne objects, usually having the antenna facing forward. The antenna itself didn't move much; the beam could sweep in 2 dimensions from a stationary antenna, sweeping much faster than a moving antenna could handle.

        When attacking ground targets, the antenna would angle slightly downward (yes, it moved, just not much). It could

  • Between the zillions of satellites destroying optical astronomy, and the zillions destroying radio astronomy, so sad too bad.

    • So, yeah... Zillions aren't a thing

      Terrestrial observatories face a lot of pressures from local light pollution, electrical discharges [theguardian.com], and activists trying to deny access to mountain tops.

      Of course they build bigger mirrors and smarter optics, fighting the inevitable dominance of space based astronomy. I appreciate that they have a lot of money in it, but SpaceX is far from a major source of light or EM pollution, and astronomy's real future is off planet. That is where money should be spent

      • I'm actually fond of "zillions" as a very big version of "lots". Few mistake it for a real number, but hearing it indicates something that feels like it's in the *illions.

        Space telescopes are certainly a promising idea, but the cost is still prohibitive. Musk could probably garner a lot of good will by offering free launches for them, but the remaining cost would probably mean there aren't a lot of takers.

        • When I see the advances in amateur astronomy (automated telescopes, etc...) I find it hard to believe it is 'dead'. Much more likely to see amateurs coordinating with published satellite tracks to choose where to look and when.

          It looks terrifying when they publish lines of satellites tracking against the sky, but those photos are immediately following launch and deployment and have little to do with actual impact of the satellites in their ultimate orbits.

          • Well, it's not dead yet, Starlink is barely getting off the ground.

            The problem is that once there's tens of thousands of these things in space, there will always be a satellite nearby - animations seem to show them about 10* to 20* apart in their orbits, and they'll be moving fast. Which renders any part of the sky near the "strands" their orbital net pretty much off-limits for any sort of sensitive astronomy. You can still look through the "holes" of course, provided you have a narrow enough field of vi

            • Some time ago, an amateur astronomer with a decent (but not exactly pro-grade) telescope and a digital imager noticed that parts of the sky were more blurry (due to atmospheric distortion) than others. He also noticed that he could image the same spot in the sky for a while, align the images (on sub-pixel boundaries), throw away the parts of the images which were blurry, keep the "sharp" parts and build a very sharp, composite image. Indeed, the composite image was accurate and considerably sharper than w

        Keep in mind that access to space has been extremely limited up to this point. Hubble for example is booked out months to years in advance, missions are extended for years or decades because there was no way to fund and launch a replacement, Only recently has tech gotten to the point where smallsats and cubesats are actually useful, and only recently have launch costs dropped below $5,000 per kilo.

            It'll be a while before we can replace all ground-based observations with satellites.

        Giant mirrors manufactured and polished to sub-micrometer precision are terribly hard to launch without breaking them. "An assload" isn't very useful if none of them actually has the resolution to see anything new. Then they're just stargazing like 99.9% of amateur astronomers do.

It would not surprise me if SpaceX is in talks with other nations' respective spectrum allocators for similar licenses. There's little point have thousands of satellites in orbit just to serve 3-4% of the most remote users of a single country.

Controllers in the CONUS were able to connect, live, to an AC-130 and direct fire on targets.

The use of space and space exploration in general is never going away. However, Tesla is showing how it can be managed correctly.
