SpaceX reveals more Starlink info after launch of first 60 satellites – TechCrunch

Last night’s successful Starlink launch was a big one for SpaceX — its heaviest payload ever, weighed down by 60 communications satellites that will eventually be part of a single constellation providing internet to the globe. That’s the plan, anyway — and the company pulled the curtain back a bit more after launch, revealing a few more details about the birds it just put in the air.

SpaceX and CEO Elon Musk have been extremely tight-lipped about the Starlink satellites, only dropping a few hints here and there before the launch. We know, for instance, that each satellite weighs about 500 pounds, and are a flat-panel design that maximized the amount that can fit in each payload. The launch media kit also described a “Startracker” navigation system that would allow the satellites to locate themselves and orbital debris with precision.

At the fresh new Starlink website, however, a few new details have appeared, alongside some images that provide the clearest look yet (renders, not photographs, but still) of the satellites that will soon number thousands in our skies.

In the CG representation of how the satellites will work, you get a general sense of it:

Thousands of satellites will move along their orbits simultaneously, each beaming internet to and from the surface in a given area. It’s still not clear exactly how big an area each satellite will cover, or how much redundancy will be required. But the image gives you the general idea.

The signal comes from and goes to a set of four “phased array” radio antennas. This compact, flat type of antenna can transmit in multiple directions and frequencies without moving like you see big radar dishes…
