[Dr Mordrid]

FCC Starlink approvals just keep coming. It's almost as if govt. agencies need it for something...

SpaceX gets OK to re-space Starlink orbits

WASHINGTON The U.S. Federal Communications Commission approved SpaceX's request to increase the number of lanes its Starlink satellites can orbit, a modification the company said would accelerate service rollout across the United States.

The FCC said SpaceX can field satellites in 72 rings around the Earth at 550 kilometers - three times as many as the commission approved in April.
>
In August, SpaceX told the FCC that by tripling the number of lanes for those first Starlink satellites, it could build out enough coverage to offer internet access in southern states by the 2020 hurricane season.
>
SpaceX is building out Starlink from the poles, with coverage expanding towards the equator as more satellites get launched.
>
SpaceX said the Starlink orbit modifications could cut the number of Starlink launches necessary by up to 50%. Under the revised plans, each of the 72 orbital rings will have 22 satellites instead of 66, meaning a single Falcon 9 launch can now populate approximately three rings. The company has been launching 60 satellites at a time on its Falcon 9 rockets. The next Starlink mission, and SpaceXs last launch of the year, is planned for late December.

60 more Starlink LEO commsats

Launch date: December 30, 2019
Launch time: 2340 pm EST (0440 UTC, Dec. 31)

Booster: ?? (B1048.5?)
Pad: LC-40
Recovery: ASDS Of Course I Still Love You

Satellite version: v1.0
Deployment orbit: 280km
Operational orbit: 550km
Frequencies: Ku & Ka bands

Note: testing at least one with an experimental coating to mitigate their brightness. Tests will measure net albedo and the thermal effects on the satellite.

[Dr Mordrid]

StarLink v1.0 is heavier than Starlink v0.9

v0.9: 230kg
v1.0: 260kg

+ Krypton for the thrusters

Date: November 11
Time: 0956 EST (1456 GMT)

Backup date: November 12
Time: 0934 EST (1434 GMT)

Stage recovery: ASDS (OCISLY)
Fairing recovery: T+45 min (Ms Tree, Ms Chief)

Deployment altitude: 280km

From the press kit

Since the most recent launch of Starlink satellites in May, SpaceX has increased spectrum capacity for the end-user through upgrades in design that maximize the use of both Ka and Ku bands. Additionally, components of each satellite are 100% demisable and will quickly burn up in Earths atmosphere at the end of their life cyclea measure that exceeds all current safety standards.

Rub: that's Veterans Day, a US federal holiday

[Dr Mordrid]

First hard number for StarLinks/Starship.

Shotwell at the Baron Fund investor conference in NYC.

CNBC...

>
Once SpaceX is flying Starship regularly, she said the rocket will be able to launch nearly seven times as many Starlink satellites at once.

"Starship can take 400 satellites at a time," Shotwell said.

This would use the Starship satellite deployer, AKA "Chomper."

Yes, it looks like Bird One from 'You Only Live Twice.'

The thing I can't grasp is how with so many (1500-10s of thousands) does this NOT impede launch windows for anything else into orbit? Launch windows are 1-2 hours at best lately and I see them dropping much smaller as StarLink ramps up satellites in orbit.

Most wide launch windows are to allow a fudge factor for handling mechanical or weather problems.

For rendezvous launches, such as Dragon launching to ISS, the window is instantaneous; they go at xx:xx;xx.xxx hours or not at all.

It is a much lower orbit than most satellites but for the mesh to work there needs to be close proximity and that equates in my head as "junk" to try to steer around when launching....

Let's go with a worst case; SpaceX has 42,000 StarLink birds in orbit.

Try to visualize 42,000 people distributed evenly across the Earth's 510,000,000 km² surface area. Each of those people will have 12,142.8 km² to themselves - almost 2x the size of Delaware. Now expand that sphere to Earth + 2x(350 or 550) km. They're even further apart.

You could send all the USAF bomber wings out, randomly dropping their loads, and not hit one soul. The same goes for an unplanned rocket launch, but very few will be unplanned.

Every StarLink bird will be tracked by NORAD, and their positions given to launch operators so they can shoot the gaps. In return, an approaching satellite's position and track will be sent to each StarLink birds AI so it can move out of the way using their Krypton Hall-effect thrusters. Besides the autonomy there will be manual supervision and control.

StarLink's satellite-to-satellite laser interlinks go live next year, closing the mesh constellation.

Gwynne Shotwell,

CNN...

The 60 satellites that we already flew are capable of operations, but the next version will have upgraded technology. By late next year, we'll be flying satellite with lasers that allow them to talk to each other in space and share data, which ensures customers will never lose service.
>
In countries where we can, we are likely to go directly to consumers. We'll have the full team of salespeople and tech support. Though, the better engineering that we do on the user terminal, the less service people we will need.

[Dr Mordrid]

SpaceX President Gwynne Shotwell told a Barron's investor conference in NYC they need 1,200 satellites to provide worldwide StarLink coverage.

SpaceX has 1,500 StarLink satellites ready to launch, Flight Provenâ„¢ Falcon 9 boosters stashed all around Cape Canaveral, and they've already started test production of the home user terminals - using SpaceX employees as "guinea pig customers."

Hiring for the full production of terminals in Seattle has already commenced.

[Dr Mordrid]

SpaceX needs 6-8 launches for Starlink to go live in the US, and is expecting to launch 4 batches this year and up to 24 next year.

The USAF test is with just one flight of satellites up and will get faster with more.

SpaceX plans to start offering Starlink broadband services in 2020

WASHINGTON - SpaceX is confident it can start offering broadband service in the United States via its Starlink constellation in mid-2020, the company's president and chief operating officer Gwynne Shotwell said Oct. 22.

Getting there will require the company to launch six to eight batches of satellites, Shotwell told reporters during a media roundtable. SpaceX also has to finish the design and engineering of the user terminals, which is not a minor challenge, Shotwell acknowledged.
>
>
Shotwell said many of the Starlink features are being tested by the U.S. Air Force Research Laboratory under a program called Global Lightning. SpaceX in December 2018 received a $28 million contract to test over the next three years different ways in which the military might use Starlink broadband services. So far, SpaceX has demonstrated data throughout of 610 megabits per second in flight to the cockpit of a U.S. military C-12 twin-engine turboprop aircraft.

[Dr Mordrid]

Space News has a write-up about the expansion to 30,000 StarLink satellites.

The first launch of operational satellites (the first was a test group) comes later this month or early November. More this year, then about 24 StarLink launches in 2020.

SpaceX submits paperwork for 30,000 more Starlink satellites

WASHINGTON SpaceX has asked the International Telecommunication Union to arrange spectrum for 30,000 additional Starlink satellites.*

SpaceX, which is already planning the worlds largest low-Earth-orbit broadband constellation by far, filed paperwork in recent weeks for up to 30,000 additional Starlink satellites on top of the 12,000 already approved by the U.S. Federal Communications Commission.
>
Here is SpaceXs full statement:

"As demand escalates for fast, reliable internet around the world, especially for those where connectivity is non-existent, too expensive or unreliable, SpaceX is taking steps to responsibly scale Starlinks total network capacity and data density to meet the growth in users anticipated needs."

Starlink is targeted to offer service in the Northern U.S. and Canadian latitudes after six launches, rapidly expanding to global coverage of the populated world after an expected 24 launches. SpaceX is targeting two to six Starlink launches by the end of this year.
