    When's the first visible passing of those 58 launched last Saturday morning?

    I don't think they are Visible here. #7 should be still visible (just about) but they'll be more spread out.

    The next Starlink is due to launch on Tuesday the 23rd June. Liftoff will be at 22:58 Irish time from Cape Canaveral, Florida and its trajectory will take it directly over Ireland about 20 minutes after launch. Hopefully we should get a great view of it as it passes over with a bit of luck.

    Saw the previous one #7 blazing across the sky, extremely bright! Definitely worth a look if it will be visible.

    Wonder how that will work if the EU give it approval. Is he giving it away for free at first to get people to sign up? Would imagine Sky/Virgin, etc will have something to say about that
    Guestimated costs are $100-$300 for kit and $80 per month.

    If SpaceX can demonstrate a working network with sub 100ms latency by the end of next month then they can apply for some of the $16Bn funding for rural BB in the US over the next 10 years.

    And lots of other countries are planning to spend billions on rural BB over the next few years.

    In theory trans Atlantic connections could be faster than fibre optic cables and in stock markets speed matters.

    Was that the pulsing light at about 2am a couple weeks back?

    This is going to be a right pain in the backside when it comes to astrophotography.

    Yea, tbh, something is probably gonna have to done to stop this.

    The novelty will wear off pretty quick. Their supposed to be sending up 40,000 of them and Bezos will probably do the same.

    Ok right, I had thought that he was doing this to bring cheap internet to the world but its not so cheap at those prices. Whats his angle here, is it purely based on broadband speeds or is he doing it because satellites would actually end up working out a lot cheaper than laying fibre everywhere?

    Doesn't pulse at all, it was a steady light across the sky. Most likely reflecting a ray from the Sun onto a cloud.

    I see Starlink have opened a mailing list for the public Beta, I have just signed up. Its open to higher latitudes first, so this includes Ireland, starts second half of 2020...

    Starlink is the cheapest, high bandwidth, solution for my location. At the moment I pay 60 per month and get 5mbs down and 0.5 mbs up, I also had to pay for the radio gear upfront, so not a dissimilar situation to Starlink.

    Saturday 13th June

    11:55pm see new STARLINKs(Jun.4 batch) in the South - about 50 of them, 10-15 seconds apart on average!!!

    12:11am(Sunday) see STARLINKs (Apr.22 batch) almost overhead (1 every 20 seconds until 12:25am)

    Im looking forward to this but the weather may not play ball. Fair bit of rain forecast for Saturday, hopefully it will pass through before midnight arrives

    It did "pulse" on the first pass, when the fairings were off the rockets and it was spinning up for release of the sats. If this launch profile is the same then you might well see the same light pulsing, which I believe comes from the rotating stack of satellites. Its a bright light, and the pulsing was just maybe 10 - 15 % reduction.

    couple of angles.

    It's not competing with Fibre to the home or cabinet or "fibre powered" broadband or anyone who can see a 5G mast.
    It's competing with DSL over long lines and ISDN and crappy mobile signals for anyone out in the Styx

    Iridium made $523 in 2018 from a network with just 66 satellites and dialup and voice on a per minute. Globalstar , Inmarsat , SES/Astra and others are also making money so there is a market even if they don't sell mass broadband.

    Light travels 30% slower through a fibre optic cable than through free space.
    IF they can get packets between London or Frankfurt to New York or Chicago faster then a LEO outfit bouncing signals between satellites could charge the stock market lots.

    It makes for an interesting JCB proof backup connection. And critters can't eat cables where there aren't any.

    SpaceX have an income of €2Bn a year on launching satellites.
    The national broadband plan in Ireland alone is €3Bn, on top of what the punters pay.

    What they are offering is decent speeds everywhere, soon, with an actual network that's in place now.
    Other constellations are rolling out too but Amazon are considered evil by some and Oneweb is bankrupt.

    5G is no use unless you can practically see the mast.

    Thanks Captain. So it can provide decent speeds but still not as fast as fibre to the home. Does that mean Musks main target market for this is the developing world or could it be of good use in rural areas of Europe/north America?

    On Iridum did you mean $523m?

    yes Iridium got half a billion

    Fibre is the good stuff because you can use more colours to increase bandwidth.
    we achieve ultra-high data transmission over 75 km of standard optical fibre using a single integrated chip source. We demonstrate a line rate of 44.2 Terabits/s
    Though on the real world field test the achievable bandwidth was only 39,000 GB/s. So it would take about one and a half seconds to fill a 12 TB drive.

    Then again by using a multicore fibre they are aiming for 0.66 Petabits/s.


    To get low latency you need low earth orbit. And that means doing an orbit in a little over an hour and a half. So you have to lots of satellites because each will only spend a short time above any location.

    http://www.circleid.com/posts/20191106_what_to_expect_from_spacex_starlink_broadband_service/
    Each orbital plane will have 66 satellites at an inclination of 53 degrees and an altitude of 550 km.
    ...
    With six orbital planes, there will be continuous connectivity in the northern US and Canada and much of western Europe and Russia, but only southern Patagonia and the South Island of New Zealand in the sparsely populated south

    ...
    With 12 orbital planes, all of the continental US and most of Europe, the Middle East, China, Japan, and Korea will be covered. Shotwell says that once they have 1,200 satellites in orbit, they will have global coverage (with the exception of the polar regions)

    A SpaceX Falcon 9 rocket is expected to launch the tenth batch of approximately 60 satellites for SpaceX’s Starlink broadband network, a mission designated Starlink 9. Two Earth observation microsatellites for BlackSky Global, a Seattle-based company, will launch as rideshare payloads on this mission. Moved forward from June 24.

    Launch scheduled for 21:18 this evening Irish time. It'll be directly over Ireland about 20 mins after launch. Shame about the weather and the thick cloud over most of the country.
