You're under impression a one-way Starlink transmitter would be a major system. It wouldn't. It would be perfectly sufficient to have it integrated into the same circuit board that runs the IMU. Such an antenna probably wouldn't be big enough to rate a separate circuit board, nevermind a breaker. Yes, the pilot will theoretically have control, but only by pulling the IMU breaker, just like with the GPS. There's no need to place for any dedicated controls outside those for maintenance.

For the record, I was not under the impression that Starlink would be a major system with its own breaker. But it would be on one of the breakers, and thus could be shut off.

Yeah. That article I linked is a pretty good summary. Also, the pilot had flown a similar path on his home flight sim. Quote Link to comment Share on other sites More sharing options...
Silavite Posted February 7, 2020 Share Posted February 7, 2020 According to Shotwell SpaceX is likely to spin-off Starlink. (In a similar manner to how they spin-off Starlink satellites from the F9's upper stage ) Quote "Right now, we are a private company, but Starlink is the right kind of business that we can go ahead and take public," Shotwell said at the [investor] event, according to a Bloomberg article. "That particular piece is an element of the business that we are likely to spin out and go public." https://arstechnica.com/information-technology/2020/02/spacex-plans-likely-spinoff-and-ipo-for-starlink-broadband-division/ Quote Link to comment Share on other sites More sharing options...

You need to be able to handle lots of customers for one and has customer support for them. Quote Link to comment Share on other sites More sharing options...

kerbiloid Posted February 18, 2020 Share Posted February 18, 2020 (edited) At last there will be no difference between the real sky and the virtual one, so the couples can watch the stars sitting in a warm and comfortable room, rather than getting cold outdoors, while astronomers can use freeware Celestia instead of expensive optics.

Treveli Posted February 23, 2020 Share Posted February 23, 2020 https://www.investors.com/news/spacex-starlink-satellites-virgin-orbit-massive-live-fire-air-force-exercise/ Didn't think of it till now, but Starlink would be useful for the military. Lots of small sats being harder to take out than a handful of big ones. Quote Link to comment Share on other sites More sharing options...

Lots of small sats being harder to take out than a handful of big ones. That and the DoD pretty much financed the rebirth of Iridium. By that point it was the main communication network of the special forces. Somehow I suspect they'd love having the same thing, but with far more bandwidth (even if the antenna needed to be mounted to something the size of a humvee roof). But the real money is connecting Wall Street with The City (and presumably the Hong Kong/East Asia financial markets) with a few less milliseconds of latency.

High bandwidth, low latency is very nice the flying UAV, very hard to even jam as you has to jam multiple satellites. High speed trading has serious money, probably more than the military, however the military has more push with the FCC and other agencys, starlink would also not be very busy over conflict zones or the ocean anyway. The real money is the high number of standard users, the real money is tend to be in the mass marked. Quote Link to comment Share on other sites More sharing options...

The real money is the high number of standard users, the real money is tend to be in the mass marked. NASDAQ traded $172,530,291,288 today (google only wanted to tell me number of shares for NYSE, but it appears to be similar) And the whole point assumes you want to link it to at least one other exchange on a different continent (more trillions). A large percentage of that is going to be high speed trading (if only because the whole point is to trade a lot). Just how you segment the market so these customers will pay what the market will bear is out of my field, but there is much more money here than in standard users, no matter how many. Whether that is a good thing or not is out of the scope of this forum. Quote Link to comment Share on other sites More sharing options...
Brotoro Posted February 28, 2020 Share Posted February 28, 2020 Looks like a nice pass of the latest batch of Starlink sats will happen at around 6:00AM tomorrow morning, and the weather is clear. I guess I get up and have a look-see. Quote Link to comment Share on other sites More sharing options...

tater Posted March 20, 2020 Share Posted March 20, 2020 https://www.teslarati.com/spacex-starlink-darksat-coating-reduce-brightnesss/?cc=2 Quote Astronomers in Chile measured the DarkSat’s brightness and compared it to the rest of the Starlink satellites. The findings show that the DarkSat was about 55% dimmer, which is good news for certain telescopes. Other telescopes, like the upcoming Vera Rubin Observatory will need the brightness reduced even further as the sensitive optics would be greatly affected by the satellites zooming across the sky. So they got some value out of the paint job, now they need to test the sun shade. Quote Link to comment Share on other sites More sharing options...

mikegarrison Posted March 20, 2020 Share Posted March 20, 2020 That's basically the business model for most of these satcom services. One company gets all the investment to build and launch the satellites, then gets buried in debt and goes bankrupt. The assets (the sats) are sold to new companies (or the original company reorganized with no debts) and operated. The losers are the people who invested in the original company, because they pay for the sats but all they end up with is the right to collect debts from a company that no longer exists.
