SAT-LOA-20170301-00027 E S2992Launch and Operating AuthorityDate Filed: 03/01/2017 17:22:30:48300Space Exploration Holdings, LLCSpace Exploration Holdings, LLC requests authority to deploy and operate a non-geostationary orbit fixed satellite system to augment an NGSO system SpaceX previously proposed for operation in Ku-band and Ka-band frequencies (IBFS File No. SAT-LOA-20161115-00018). SpaceX seeks authority to add V-band spectrum to the 4,425 NGSO satellites previously proposed to allow the use of both Ku- and V-band spectrum for user links, and both Ka- and V-band spectrum for gateway links and tracking, telemetry, and command functions. Space X also proposes to add a very-low-Earth orbit NGSO constellation, consisting of 7,518 satellites operating at altitudes from 335 km to 346 km, using V-band spectrum for all links to and from associated earth stations. The V-band frequencies proposed are: 37.5-42.0 GHz (space-to-Earth), and 47.2-50.2 GHz and 50.4-52.4 GHz (Earth-to-space). We defer consideration of SpaceX's application for authority to operate in the 42.0-42.5 GHz band, which is not allocated for non-Federal fixed-satellite service in the United States and do not accept for filing this portion of SpaceX's application at this time. SpaceX requests waiver of sections 2.106, 25.202(a)(1), 25.143(b)(2)(ii), 25.156(d)(4), 25.156(d)(5), 25.157(e), 25.164(b), 25.208(r), and 25.114(c)(8) of the Commission's rules, and, to the extent necessary, various limitations in the Commission's Schedule S, in connection with this application.This application is part of the processing round established in Satellite Branch Information: Boeing Application Accepted for Filing; IBFS File No. SAT-LOA-20160622-00058; Cut-Off Established for Additional NGSO-Like Satellite Applications or Petitions for Operations in the37.5-40.0 GHz, 40.0-42.0 GHz, 47.2-50.2 GHz and 50.4-51.4 GHz Bands, Public Notice, DA 16-1244 (rel. Nov. 1, 2016).
SES asks ITU to replace ‘one and done’ rule for satellite constellations with new system
International regulators are weighing whether to tighten rules that permit owners of large satellite constellations to launch a single spacecraft to meet their in-service deadline, a policy seen as allowing an operator to block the use valuable radio spectrum for years without deploying its fleet.Satellite fleet operator SES, which is taking an active role in the regulatory debate, has proposed to regulators a compromise that recognizes the unique nature of large constellations while also enforcing much stricter requirements.
The FCC is asking constellations in non-geostationary orbit to field their entire fleets within six years of receiving their FCC licenses. SpaceX and Boeing have asked the FCC to adopt a more-flexible requirement, saying that the realities of the satellite production and launch industry make it all but impossible to launch huge numbers of satellites within six years.SpaceX has said it could launch 1,600 satellites, each expected to weigh 386 kilograms, in the six-year period — more than sufficient to prove its seriousness, the company told the FCC. Boeing has also asked for a waiver of the six-year deadline:http://bit.ly/2urUZrs
..realities of the satellite production and launch industry make it all but impossible to launch huge numbers of satellites within six years.
Greg Wyler, chairman of OneWeb, a constellation of at least 800 satellites in low Earth orbit, has said he would have no objection to a much stricter deadline regime at the ITU. OneWeb has scheduled the launch of 10 demonstration satellites in mid-2018, with the rest of the network to be in orbit by 2020, mainly through 21 launches of Russian Soyuz rockets, contracted through Arianespace.OneWeb has also contracted launched with Virgin Galactic’s LauncherOne and Blue Origin’s New Glenn vehicles.
None of SpaceX's constellation is going to sun-sync, so I find it odd that they would launch the test birds there. Possible, but very odd.
Haven't seen a post of the recent FCC response to comments and requests, posted and dated Sept 7.

I posted it earlier today but the thread title didn't have SpaceX in it so most people won't read it https://forum.nasaspaceflight.com/index.php?topic=41647.msg1720966#msg1720966
I've found this blogpost which claims that the first two SpaceX test satellites are going up in late 2017 on the PAZ mission from VAFB. This seems to be based on sharing a sun-synchronous orbit at 514 km altitude with an inclination of 97.44 degrees.I'm not entirely sure I believe this. I don't know all that much about orbital mechanics but wikipedia claims sun-synchronous orbits form families with shared parameters? So it's possible that the first sats will go on one of the later SSO launches.
Later this year, SpaceX will begin the process of testing the satellites themselves, launching one prototype before the end of the year and another during the early months of 2018. Following successful demonstration of the technology, SpaceX intends to begin the operational satellite launch campaign in 2019. The remaining satellites in the constellation will be launched in phases through 2024, when the system will reach full capacity with the Ka- and Ku-Band satellites. SpaceX intends to launch the system onboard our Falcon 9 rocket, leveraging significant launch cost savings afforded by the first stage reusability now demonstrated with the vehicle.
didn't even know we had an FCC thread
I really don't get the focus on the international sharing rules in that blog post. I don't see how the FCC would have any right to specify the sharing methods outside the U.S. for non-U.S. registered constellations, just because they had access to the U.S. market. (Someone on Reddit also noticed that the picture from a SpaceX presentation that is presented as possibly being the SpaceX sats in that blog post are actually NASA satellites.)Quote from: vaporcobra on 09/09/2017 04:47 amdidn't even know we had an FCC thread I've been sticking stuff in there that is applicable to the entire NGSO processing round and not really SpaceX specific. It also has handy links to all the other filings farther up in the thread. I was going to quote it here but forgot.
"Compliance with ITU coordination procedures is a requirement of the ITU Radio Regulations, which hold the force of treaty to which the United States is a party. Such compliance is a typical condition of both U.S. space station licenses and grants of U.S. market access."
What's the fuss about? Turning off the beam in a certain direction when SpaceX's satellite passes in front of another satellite's beam has always been at the core of SpaceX's plans. Misleading to call it "disabling," though.And take "consultant" with a grain of salt. (Strongbad voice) "Isn't that what people put on their resume while they're unemployed?"
Teslarati take on issues SpaceX has with the FCC decision.http://www.teslarati.com/spacexs-plan-launch-internet-satellites-face-possible-setback-recent-fcc-decision/
Seems SpaceX are planning to launch their test satellites this year. Would this not put them ahead of the competition?
