Nome, AK filing: https://licensing.fcc.gov/cgi-bin/ws.exe/prod/ib/forms/reports/swr031b.hts?q_set=V_SITE_ANTENNA_FREQ.file_numberC/File+Number/%3D/SESSTAINTR202300012&prepare=&column=V_SITE_ANTENNA_FREQ.file_numberC/File+Number

SpaceX Services, Inc. (“SpaceX Services”), pursuant to Section 25.120 of the Commission’s rules, hereby requests Special Temporary Authority (“STA”) to add additional Ka- band frequencies to and lower the minimum elevation angle of its polar gateway earth station in Nome, Alaska (the “Nome gateway”) to support the critical early-mission period, including orbit raising, of upcoming high-inclination launches of non-geostationary orbit (“NGSO”) satellites operated by its sister company, Space Exploration Holdings, LLC (“SpaceX”).


Lowering the min. elevation to 5 degrees (from 25), and adding 27.5-28.35ghz.

SpaceX is asking FCC to apply the same conditions in Gen2 authorization to other constellations, so far they have filed request against Kuiper V band and AST SpaceMobile constellation.

The 5 conditions they asked FCC to require other constellations to meet are:
• file semi-annual reports on collision avoidance maneuvers and satellite disposal, including
any difficulties or failures related thereto;
• apply a new performance-based method for assessing disposal failures that accounts for
both the number of failed satellites and their entire passive decay time;
• communicate and collaborate with NASA to promote space safety and sustainability;
• take all possible steps to assess and mitigate collision risk after receiving a conjunction
warning from the 19th Space Defense Squadron or other source; and
• coordinate with NSF to reach a mutually acceptable agreement to mitigate the impact of
its satellites on optical ground-based astronomy, with associated annual reporting
requirements.

From the STA for using the VHF beacons on Gen 2 sats, SpaceX was granted permission to use them on some of the requested frequencies for up to 15 satellites for 30 days.  I assume they'll be able to file extensions when the 30 days is up.

so far they have filed request against Kuiper V band and AST SpaceMobile constellation.

Also against OneWeb, Telesat, Viasat, Hughes, O3b, Boeing, Planet LabsIntelsat, and 17 other satellite operators.

Would some kind soul attach the relevant docs to this thread - the links above take me to a login/public notices page on which these can not be found.

Thanks in advance.

The trick with the FCC website is to click a bunch of times and eventually it will download  :o

They are basically form letters with INSERT_CONSTELLATION as far as I can see.

Since SpaceX already launched to Gen 2 orbits several times but with Gen 1 sats, will it count as 7500 FCC-approved slots or not?
My parents was just being born when the Apollo program is over. Why we are still stuck in this stagnation, let's go forward again

Yes

Note that at a later date SpaceX can (and likely will) replace these early satellites in the Gen 2 orbits with the Starlink Gen 2 Starship version, but that will likely come at a later date.

7500 is just the number approved for now.  It does not prevent the FCC from approving the full constellation later. Even with an operational Starship, it will take them a couple of years to launch the initial 7500.

Though it might take some extra paperwork, at some point the v1 and v1.5 phase 1 satellites will need to be replaced.  At that point the replacements will most likely be what ever the latest version of the Starship Gen. 2 satellite have evolved into.

SpaceX has requested additional Special Temporary Authority to operate additional VHF beacons on Gen2 Satellites.

Asking FCC again for 60 days, 300 beacons STA.

New information: Maximum of 56 beacons per launch, operates for about 4 weeks during orbit-raising.

SpaceX withdrew their FCC filings for the T-Mobile cell service and for using the GlobalStar frequencies.  I'm not sure exactly what that means.  They can always be refiled.

SpaceX have seemingly already re-applied for Direct-to-Cell



"At full deployment, this hosted payload will enable SpaceX to provide full and continuous
coverage of the Earth within ±58° latitude by mid-2024."



Now will be deployed on up to 7500 sats.

Quote from: Seth Miller
Comparing the applications, there are some key differences. The 2023 version is showing as an amendment to an existing application (SATLOA2020052600055); the 2022 version was a new request.



Yeah, the new application is to modify the now partially approved Gen2, adding an antenna, frequency, and emission designator/service.



The original app also specified that the PCS frequencies would be served by a "German-licensed" payload. The revised version no longer has it as a foreign payload.



Only other difference I can see in the PCS applications is that the now withdrawn one is from Space Exploration Technologies Corp and the others are from Space Exploration Holdings, LLC.

https://fcc.report/IBFS/SAT-AMD-20230207-00021: SpaceX requests authorization to operate its direct-to-cellular payload to communicate on an unprotected, non-interference basis in the 1910-1915 MHz uplink E-s and 1990-1995 MHz downlink s-E bands PCS G Block with off-the-shelf cellular mobile devices ot

https://fcc.report/IBFS/SAT-AMD-20230207-00022: SpaceX application to provide mobile satellite services in the 1610-1617.775 MHz uplink E-s, 2000-2020 MHz uplink E-s, 2020-2025 MHz uplink E-s, 2180-2200 MHz downlink s-E, and 2483.5-2500 MHz downlink s-E band on SpaceX Gen2 satellites.

Haven't read them in full yet, but seems like for the 1.6GHZ-2.4GHz and 2GHz application, they just switched from Gen1 to Gen2, and for the T-Mobile application they increased # of satellite with payload from 2,016 to 7,500.

As I said, FCC is not applying the requirement they put on Gen2 to other constellations:

https://spacenews.com/amazon-gets-key-fcc-approval-for-more-than-3000-leo-broadband-satellites/

Quote
The FCC also shot down an attempt to add the “object years” limit to Kuiper that came with Starlink’s Gen2 approval in December.

<snip>

The FCC said SpaceX had already launched thousands of Starlink satellites when it imposed this condition on the company, which also had actual satellite failure data that the regulator could use to inform this monitoring approach.

“As Kuiper has not started deploying or operating its constellation, we find it is not … necessary to impose such a condition at this time,” the order stated.

“Once Kuiper begins launching and subsequently operating its constellation, we will reassess the need to add a similar condition at a later date.”

Isn’t this like letting a new airplane manufacturer do whatever until it’s planes start crashing? If they set a minimum for Starlink, it has to be a minimum for all.

I can’t see this surviving a lawsuit.

Well yeah, but SpaceX needs FCC to fight off space NIMBYists, the latter is a bigger enemy, so I don't think they'll antagonize FCC at this point.

Interesting, @SpaceX filed w/ FCC a request to modify its Gen 1 system to upgrade its satellites deployed under its Gen 1 authorization. Application available here https://bit.ly/3Yx2S9z. Will need a closer review to determine full delta b/t current auth and this mod app.

File Number is SAT-MOD-20230215-00036

As expected, this is SpaceX asking to launch v2 satellites into Gen1 orbits, the description didn't make it clear, but in footnote 17 of Technical Attachment A.11, they said this:

Quote from: Technical Attachment A.11, footnote 17
Table A.11-1 presents information for the proposed form factors of SpaceX Gen1 satellites, one of which will be launched initially on Falcon 9 rockets and one that will be launched on Starship. For convenience, these satellites are labeled as F9 and SSP, respectively.

I think it's safe to assume these are the F9-2 and Starship satellites in the Gen2 application.

Yesterday's SpaceX filing was extremely vague, even for SpaceX, and didn't even have the Schedule S attached.
