SpaceX gets FCC approval to deploy thousands more internet satellites
"SpaceX's plan to build a global, high-speed wireless internet network using
satellites has taken another step forward. The FCC approved the company's request to deploy more than 7,000 very-low-Earth orbit satellites for its Starlink network. It follows the regulator giving SpaceX the green light in March to launch 4,425 satellites. When it's complete, Starlink will be comprised of almost 12,000 satellites that will blanket the planet with a persistent internet connection. That should mean people in rural areas or other locations where more traditional types of connections are impractical can access a network with promised speeds of up to 1 Gbps."

See: https://www.engadget.com/2018/11/15/...et-satellites/ That's a lot of satellites! That's why they need to incorporate as much reuse as possible into Falcon. Still working on fairing recovery. Update on Twitter from Elon today. SpaceX will not make the upper stage of Falcon reusable. Concentrating on BFR/BFS. Speaking of BFR/BFS, apparently they've iterated the design again. No details as of yet, of course. It will be interesting to see if the upper stage test next year incorporates these latest changes (whatever they are).

SpaceX gets FCC approval to deploy thousands more internet satellites
People in the artic and rural regions will be extremely pleased with this
development. Many of them can't get decent internet at the moment. wrote in message ...

I know the concept of BFR/BFS is meant to be fully reusable. But in a context of launcing satellites, doesn't BFR act as a Falcon 9 stage 1 and there is still some need for some stage 2 to move stallites into position and jettison each at the right time ? No. I'm pretty sure if you read the FCC documents related to Starlink, you'd fine information like this. As for Starlink ground stations, they won't be anything like traditional ground stations. If you read a few articles on Starlink, you'd know this. The concept of satellites talking to each other to reach one with a downlink is not new. In other words, you can't be bothered to even marginally educate yourself so that you can manage a semi-intelligent conversation on the subject. It expands on the spot beam principle by spreading beams over many satellites that then "find" the one satellite nearest to them that currently flying over a ground station. So the capacity from many satellites is funneleed onto the nearest one with uplink connection to a ground station, putting even more demand on capacity for that link which is still limited by the allocated spectrum to that satellite operator. Space side network is lasers, not RF. Only ground station communication uses radio. Where there is improvement is if someone in Resolute Bay sends data to someone in Iqaluit. Currently data goes to geo satellite then back down to Toronto ground station (Xplornet) then back up to same satellite and back down to Iqaluit's dish. With the new model, it become theoretically possible for the packet to go up to one satellite, transit to whateere satellite is over ioqaluit and back down, eliminating the big long hops or the use of a ground station. No, because individual users won't have the capability to receive and transmit on Starlink ground frequencies. But when you look at the structure of the Internet, most of the traffic goes to very centralised places (an city that has Netflix, Google, Amazon, Level3, Akamai etc servers). Home to home traffic is light and couwl dconsist of gaming and Skype stuff. You seem very confused about both the architecture of the internet and the intended architecture of Starlink. Early Starlink satellites will have a 3 year lifetime, so they can easily be replaced with upgraded satellites every 3 years. Satellites aren't the problem. Ground stations are. Why do you think that? Ground stations are just ordinary ISP server farms with some antennae. This dovetails nicely with BFR. Essentially SpaceX will be launching satellites every single year to keep the Starlink constellation up to date. Yet, people believe the claims that such services will be far more affordable than current services. Because BFR/BFS will be a fully reusable system it will be preposterously cheap compared to any system (including Falcon 9) in use today. Have fund with your 1gbps speed on satellite when you monthly usage is limited to 5 GB. I'm going to go out on a limb and guess that you just pulled that "information" out of your ass. https://www.xplornet.com/shop/our-internet-packages/ Postal ode X0A0R0 (Pangnirtung) (the "0" are all zeros in postal code) The satellite services in the USA are not as bad. But Xplornet has been promising amazing thinsg with its "4G" satellites when they launched and nothing much changed with their rates and monthly limits when the new satellites were put int production. So sorry to rain on your parade, but don't expect Starlink to be that different. Someone has to pay for lanching these thousands of satellites. Thank you for demonstrating that you did indeed pull that number out of your ass. Comparing Starlink to an existing service is rather like claiming that mere hours in transport between cities at prices much cheaper than buying a Conestoga wagon is impossible. -- "Some people get lost in thought because it's such unfamiliar territory." --G.

Cargo BFS. BFR is sometimes used to refer to the entire two stage vehicle. Given reusability and the cargo capacity, BFR should cost around $75/kg to LEO. This dovetails nicely with BFR.

Yet, people believe the claims that such services will be far more affordable than current services. Because the satellites will essentially be mass produced. The ground hardware will be mass produced (a phased array antenna with associated hardware that essentially acts like a high powered cable modem). Hughes (Explorenet leases satellite capacity from them) says it costs around $500 million to build and launch a satellite to orbit. They're launching on ULA Atlas V as a single payload, so just the launch costs are well north of $100 MILLION. Meanwhile, launch costs for a Starlink bird should be well south of $40 THOUSAND. Explorenet paid $200 million to lease their current block of bandwidth on one satellite. The second satellite presumably has similar costs.

Someone has to pay for lanching these thousands of satellites. Things that are different, just aren't the same. Yeah. Design and buildout of the Starlink constellation (7500 satellites) is expected to cost around $10 billion. That comes out to around $1.33 million per bird, or less than 1% of what an Explorenet satellite costs them (at $200 million). Bottom line is that Explorenet paid $0.4 billion to get (apparently expensive and limited) Canadian service in place. For around 25 times that cost, Starlink will have worldwide service with much higher bandwidth. -- "The reasonable man adapts himself to the world; the unreasonable man persists in trying to adapt the world to himself.
