Adding the text below because you can't select it in the PDF:

Quote
This letter corrects the record in response to misleading and incorrect filings
recently submitted by Viasat, Inc. and Hughes Network Systems, LLC (collectively,
"GSO operators" or "GSOs"). In both filings, the GSO operators, neither of whom has
ever operated any satellites in Low Earth Orbit ("LEO"), repeat false assumptions and
misrepresent record filings in a strained effort to reach false conclusions about how
SpaceX's non-geostationary orbit ("NGSO") satellite system works. In contrast, SpaceX
is operating more than 700 LEO satellites that are already providing high-quality
broadband service to users, and has conducted millions of performance tests on its network.

In short, while the GSOs postulate theoretical claims about how they might operate
an NGSO network and their inability to provide low-latency service, SpaceX has conducted
millions of tests on its actual operating equipment that demonstrate definitively it can
deliver to consumers a true low-latency broadband.

SpaceX Has Run Extensive Real-World Tests That Show Conclusively That Its
System Delivers Low-Latency Service.


The GSOs' arguments about SpaceX's latency hinge entirely on the assertion that
because SpaceX used a few images of screen tests for illustrative purposes in a previous
presentation to the Commission, SpaceX lacks other data to support the parameters of its
network performance. But the GSOs are reading too much into a single image used in an
overview presentation. Indeed, if true, Viasat's contortions about latency would seem to
call into question the credibility of its own stated reason for asking to modify its
authorization for its NGSO system—to operate, for the first time, its own low-latency
service from an altitude twice as high as SpaceX.

In fact, SpaceX has now conducted millions of tests on actual consumer-grade
equipment in congested cells, showing consistent observed median latency of
approximately 30 ms. These end-to-end latency measurements—based on actual data, not
theory—include all sources of network latency. Contrary to the GSOs' claims, these beta-
test results of latency and throughput are not "best-case" performance measurements.
Rather, they reflect testing performed using peak busy-hour conditions, heavily loaded
cells, and representative locations. If anything, SpaceX's beta testing uses conditions
designed to support on-going optimization and testing of the network that make network
performance measurements worse, not better. For example, all the user terminals were
configured to transmit debug data continuously, even if the beta customer didn't have any
regular internet traffic, forcing every terminal to continuously utilize the beam.

Moreover, these results are based on beta-test software frame grouping settings that
do not yet reflect performance using the software designed to optimize performance for
commercial use. Until recently, the network had been grouping user terminals in groups
of 8 per radio-frame, instead of the 20 terminals per radio-frame the system supports. This
operating choice is to support on-going optimization and testing of the network but has the
consequence of introducing 2.5 times longer delay between radio-frames for a given user
in a fully loaded cell, corresponding to the smaller group sizes. Importantly, this software
feature has just been enabled and is specifically designed to optimize speeds in highly
populated cells, increasing throughput by approximately 2.5 times.

In addition to the datapoints representing SpaceX's aggregate performance, SpaceX
analyzed the last week of measurements for a community of 30 high-usage customers. As
shown in Figure 1, these measurements, totaling 1,048,576 datapoints, indicated a
95th percentile latency of 42 ms and percentile latency of 30 ms between end users and
the point of presence connecting to the Internet. These measurements confirm the SpaceX
network is capable of allocating resources efficiently such that latency remains consistent
whether the measurement point is the overall network or individual groups of customers.

*Figure 1. One Week of Latency Measurements (15 second data, 30 users)*

The Commission should not be distracted by self-interested, ill-informed
speculation from GSOs that have never operated an actual low-latency system. Instead, it
should rely on actual data that SpaceX has provided the Commission.

Viasat's Conclusions About SpaceX Operations Are Based on Documented
Misrepresentations and Skewed Analysis.


Viasat steadfastly refuses to allow facts to get in the way of the story it wishes were
true. To support its claims about SpaceX's operations, Viasat relies extensively on research
by Professor Jonathan McDowell. SpaceX urges the Commission to review the letter
Professor McDowell himself filed in the record in which he called Viasat's filing a
"misreading of my results" and stated that Viasat's analysis is an "inexplicable
interpretation."

SpaceX is fully transparent about reporting when satellites lose maneuvering
capability. All satellite failures are marked on space-track.org, to which every operator
and the public at large have access. SpaceX has been continuously and diligently working
to upgrade its satellites as technology improves. As a result of these upgrades—and as
SpaceX has previously reported, but Viasat continues to ignore—the last 233 satellites
SpaceX has launched have had no failures at the time of this filing. Nonetheless, SpaceX
continues to work to improve the performance and reliability of its vehicles.

Despite the heated rhetoric from competitors, SpaceX's modification will in fact
significantly improve its safety profile and ensure consumers have access to a truly low-
latency service. The Commission would be particularly justified in discounting claims
from Viasat, given its ongoing misrepresentations and its apparent flaunting of
Commission rules by its seeming unauthorized use of certain spectrum bands.

The Commission should quickly approve SpaceX's modification.

From https://fcc.report/IBFS/Public-Notices/2728358

Quote
SES-LIC-20190816-01063

This application has been amended by IBFS File Number SES-AMD-20200220-00178 to operate this Ka-band gateway with eight technically identical 1.5-meter antennas in Loring, Maine.  SpaceX originally applied for authority to transmit in the 28.35-29.1 GHz and 29.5-30.0 GHz bands and receive in the 17.8-18.6 GHz and 18.8-19.3 GHz bands. However, it deferred in requesting authority to operate this earth station in the 27.5-28.35 GHz band designated for use by the Upper Microwave Flexible Use Service (UMFUS) on a primary basis, with a secondary designation for FSS.

SpaceX has completed its analysis of the Loring Gateway site so that it can demonstrate compliance with the requirements of Section25.136(a)(4) of the Commission's rules such that this earth station may operate without providing additional interference protection to terrestrial UMFUS systems operating in the band.  Technical Appendix A demonstrates that the Loring Gateway will satisfy the criteria set forth in Section25.136(a)(4).

SpaceX also submits with this amendment updated antenna performance information for its gateway operations. SpaceX will comply with a mask similar to the one in Section 25.209(a)(3) applicable to earth station antennas operating in the 24.75-25.25 GHz and 28.35-30.0 GHz bands with geostationary satellites but will improve that pattern to -3 dBi (rather than 0 dBi) beyond 25 degrees off-axis.

 Viasat is at the end of a long line of different names who have all pulled the same scam of prioritizing demonstrations to clients before cramming them into ludicrously over subscribed services. They think if they change their name every few years, nobody will know it's the same operation. You'd think it would be surprising that they'd spout such easily disprovable nonsense, but nobody who had dealt with them under any label is that shocked. It tells you all you need to know about the mindset of the company execs.
 And that was my civil response. Long story.

I completely overlooked those filings on Friday.  When you link to the FCC site please put the link to this page instead of just the attachments.  Some of the FCC pages have a serious lack of navigation options.

Nice, the US looks pretty well covered already head of the public beta.

Do you thing you could start adding international gateways as well? I think we might see international service sooner rather than later.

Canada became the first country to host Starlink usage after the USA. https://teslanorth.com/2020/10/18/spacex-starlink-internet-approved-canada/

ps, if the mods want to move this, fine, I just couldn't find a better place.

SpaceX filed for a Ku-band gateway at McGregor, which is a little odd at this point.  I guess they'll use the Ku gateways for testing the payloads after launch?

https://fcc.report/IBFS/SES-LIC-INTR2020-03198
It could be a high throughput test configuration for using Starlink as a Internet Backbone for a "remote" ISP. The ISP would be a local ISP in McGregor that then does normal distribution to customers using it's own currently existing system.

The information to determine likelihood of this explanation would be is how close is the local ISP tech center to the Gateway.

SpaceX filed for an experimental permit to mount user terminals on up to five Gulfstream jets for a two year trial.  I guess the SpaceX corporate jet is going to get an internet upgrade.

0955-EX-CN-2020
Quote
The Commission has previously granted experimental authority to test these same user terminals at various locations within the United States.3 In order to expand its assessment of the end-to-end capabilities of its satellite system, SpaceX seeks authority to test up to five user terminals electrically identical to those covered by its blanket license when mounted on a Gulfstream jet for a period of up to two years. Specifically, SpaceX seeks experimental authority for operation of one user terminal aboard each of up to five private jets while they are (1) on the ground at an airport, and (2) in flight over the United States (including its territories and territorial waters). Such authority would enable SpaceX to obtain critical data regarding the operational performance of its user terminals and the SpaceX NGSO system more broadly.
