Public Notice from the FCC on the Ku/Ka band processing round. It lists all of the constellation filings accepted so far with their number of satellites, orbits, frequencies, and where they will be licensed. A round of public comments and replies starts on June 26.They also established a cutoff for additional Ku/Ka band NGSO applications to be filed by July 26.The V-band filings are being handled separately from the Ku/Ka band filings, so there should be another of these documents eventually for the rest of the constellation filings.
Nice find. Makes sense, both the Telesat and Space Norway constellations are minuscule relative to all other applicants.
Quote from: vaporcobra on 10/09/2017 08:06 pmNice find. Makes sense, both the Telesat and Space Norway constellations are minuscule relative to all other applicants.The only really big applications are SpaceX, Boeing, OneWeb. Of the rest, isn't Telesat is the biggest? (roughly twice as big as Iridium)
[SpaceNews Nov. 6, 2017] FCC grants Telesat LEO market access despite ViaSat protestsFollowing market approval given to OneWeb in June, the U.S. Federal Communications Commission on Nov. 3 granted global fleet operator Telesat permission to reach the U.S. with a constellation of 117 low-Earth orbit satellites....Canada-based Telesat is the second LEO constellation after OneWeb to receive market access from the United States.The FCC also granted Space Norway market access Nov. 3 to reach the U.S. with two satellites in non-geostationary elliptical orbits. Both Telesat and ViaSat sought to block Space Norway.
Any news regarding FCC ruling for SpaceX constellation ?
If my proposal to grant @SpaceX's application is adopted, it would be the 1st approval given to an American-based company to provide broadband services using a new generation of low-Earth orbit satellites.
Paper from AIAA Space 2017Large Satellite Constellation Orbital Debris Impacts: Case Studies of OneWeb and SpaceX Proposalshttps://arc.aiaa.org/doi/pdfplus/10.2514/6.2017-5200Quote from: AbstractRecent proposals for large constellations of communications satellites have added to the debate surrounding the long-term impact of large satellite constellations on spectrum regulation and orbital debris propagation. The many spectrum license applications currently before the Federal Communications Commission for large, non-geostationary satellite constellation systems provide the satellite risk community with a unique opportunity to weigh the promise of these missions against their long-term impact on the orbital debris environment prior to their launch. The last decade has seen approximately a 60% increase in the total orbital debris object count, and the additional impact of these pending proposals could significantly alter the LEO environment. Furthermore, regulators should examine these proposals within the existing space policy framework to identify potential regulatory inefficiencies. Much of the existing literature focuses on the risk that the orbital environment poses to satellite constellations and distributed spacecraft missions, but the pending constellation requests can serve as case studies for examining the risk that large satellite constellations pose to the orbital environment. Better understanding the proposed systems will offer insight into the risks that mission managers and regulators may be accepting now on behalf the future space community. By examining the licensed OneWeb broadband services satellite constellation and the proposed initial deployment of a similar SpaceX system using the NASA Johnson Space Center Orbital Debris Engineering Model software (Version 3) and a small Monte Carlo analysis, we are able to examine potential implications of the proposed missions, as well as the policy decision space that may emerge as these proposals are reviewed over the coming months and years.

we assume that each spacecraft is capable of withstanding an impact by any orbital debris less than 1 centimeter in diameter and that such a collision results in no change in performance of the spacecraft.

A 1-centimeter piece of debris is enormous and would be catastrophic for all but very heavily-shielded vehicles.

A 1-centimeter piece of debris is enormous and would be catastrophic for all but very heavily-shielded vehicles.Yes, and no.If you consider the whole cross-sectional area of the spacecraft, in most of that cross-sectional area, it's going to hit a solar panel and punch clean through.If the solar panel is appropriately constructed with redundancy, his may cause no meaningful change in performance, most of the time.
I mean this news may be interesting - 10 minutes ago I received mail://Dear valued LeoSat Partner, We very much appreciate your interest and commitment to LeoSat and with this letter I would like to update you on the latest developments.LeoSat as a NewSpace company is confronted with the same challenges of any start-up that is moving along the evolution from vision to reality. Whilst the company maintains its strong vision as a unique solution for B2B data connectivity in LEO, validated by the market and our early investors, we are now facing critical funding issues. Late last week we had to make the very difficult decision to cancel our early obtained FCC license that required a long term financial commitment equal to that of multiple FTEs. As a startup we could no longer justify carrying the cost this early in the project and we will reapply for this license closer to launch, in parallel to obtaining our licenses in other countries. //Starlink will have minus one competitor and more interest from investors
25. IT IS FURTHER ORDERED that this authorization is also subject to the followingrequirements:a. LeoSat must post a surety bond in satisfaction of 47 CFR §§ 25.165(a)(1) & (b) no laterthan December 19, 2018 and thereafter maintain on file a surety bond requiring payment in the event of adefault in an amount, at minimum, determined according to the formula set forth in 47 CFR §25.165(a)(1); andb. LeoSat must launch 50 percent of the maximum number of proposed space stations, placethem in the assigned orbits, and operate them in accordance with the station authorization no later thanNovember 19, 2024 and LeoSat must launch the remaining space stations necessary to complete itsauthorized service constellation, place them in their assigned orbits, and operate each of them inaccordance with the authorization no later than November 19, 2027. 47 CFR § 25.164(b).Failure to post and maintain a surety bond will render this grant null and void automatically,without further Commission action. Failure to meet the milestone requirements of 47 CFR § 25.164(b)may result in LeoSat’s authorization being reduced to the number of satellites in use on the milestonedate. Failure to comply with the milestone requirement of 47 CFR § 25.164(b) will also result inforfeiture of LeoSat’s surety bond. By December 4, 2024, LeoSat must either demonstrate compliancewith its milestone requirement or notify the Commission in writing that the requirement was not met. 47CFR § 25.164(f).
In accordance with Section 25.165 of the Commission’s rules, 47 C.F.R. § 25.165, and paragraph25.a of the Order and Declaratory Ruling1 granting access to the U.S. market to LeoSat MA, Inc.(“LeoSat”) for the operation of a non-geostationary satellite system operating in Ka-bandspectrum, LeoSat hereby submits the attached surety bond rider.The surety bond rider increases the overall bond amount by $20,000 to $1,570,000 which is theamount required to cover the period through and including September 27, 2019 pursuant to theformula set forth in Section 25.165(a)(1) of the Commission’s rules.LeoSat and the surety will execute a further rider to the bond on or before September 27, 2019 to increase the amount of thebond in accordance with the Commission’s requirements.
PARIS — Startup satellite broadband B2B provider LeoSat has suspended operations — which in recent months has mainly consisted of looking for investors — and laid off all its staff in the wake of...
