Location of a proposed Starlink Ground Station at CCAFS next to the SpaceX Fairing Processing Facility [BLDG 70507 at CCAFS, the old Titan era Payload Fairing Cleaning Facility].


Edit to add St Johns River WMD link (thanks for reminder gongora!)

https://permitting.sjrwmd.com/epermitting/jsp/Search.do?theAction=searchDetail&permitNumber=161809

It looks like they removed the document links from the site, a reminder to always save the files (which I didn't).

There is an FCC filing for a Ka-band Starlink ground station at a different spot on CCAFS now.

So did Elon say they can start offering initial services with around 400 sats in orbit? If so that milestone will be reached tomorrow by my count.

I would presume Elon meant that the satellites need to be not in some arbitrary orbit, but in very specific ones. According to this data by Hummy, only 114 Starlink satellites have reached their target orbits so far. And it seems to be taking at least 4 months for each batch to populate the 3 corresponding orbital planes. So the milestone should be reached by the end of summer, I believe.

You can forgot about first 62 Sats   TinTin+Starlink V0.9  . This sats need uplink on Gateway  in Ku band .

According to  FCC approval Standart for  Gateways is Ka band ..
And I mean that StarLink V1.0  work  in Ku (downlink) and Ka (uplink)  ...

The six launches of V1.0 sats should allow service in northern U.S., and as mentioned above probably not until at least September (assuming they get everything else, including user terminals, ready by then).

Thanks. Do we have an estimate of how many customers they can realistically service with these 360 sats? In other words, how many customer subscriptions they can potentially generate from September?

Thanks! We are taking some key steps to reduce satellite brightness btw. Should be much less noticeable during orbit raise by changing solar panel angle & all sats get sunshades starting with launch 9.

Now if only I was sure what he meant by "launch 9"  :-\  :)

Is there a reason they’ve been brighter and more noticeable lately? I feel like tons of people are spotting them all of a sudden and they went fairly unnoticed before.

Solar panel angle during orbit raise / park. We’re fixing it now.

In what world were they "fairly unnoticed before"?  Seems like there was a LOT of visibility (har) from the very first launch.

I guess the geometry changed with the more recent trajectories... perhaps that made it worse?

There are not 420 operational Starlink satellites.

"Operational" being the important term here that might be debatable. ;) The last batch is in orbit but not at an operational altitude and phase.

As far as the count itself, a few have been deorbited, but the two first prototypes (Tintin A & B) are still up there, but appear to be in the process of being brought down. But he could be counting them too.

What is the accurate number of Starlink satellites in orbit, Gongora?

If you count the Tintins then 419, at least a few of which are being deorbited.

How many Starlink launches needed until minor/moderate coverage? Are you still targeting service in the US & Canada by end of this year?

Did one of the V1.0-L4 sats get deorbited? Celestrak is only showing 59 for that batch.

Yes.  One each from v0.9, v1.0 L2, v1.0 L4 have deorbited so far.

I estimate there are now 412 operational Starlink sats with 3 reentered, 2 Tintin prototypes retired, and 5 apparently dead in orbit

edit: Hummy's list in the tracking thread also had 5 broken sats.  I'm still not sure how "operational" the v0.9 sats are meant to be long-term, I'm assuming they wouldn't actually be used for normal customer traffic.

I agree with you that these are not all operational satellites.
Can't you feel for Musk's enthusiasm, their closest competitor recently declared bankruptcy they again accomplished something no one else has done.

lighten up.

Is there a specific latitude and north that will have service first or is that not known yet?

Based on this video linked below latitudes between ~40 and ~56 will have continuous coverage in this initial version.
