Viasat shrinks MEO constellation plans - SpaceNews.com Nov 2018
"... another satellite operator is reducing the size of its proposed constellation. Viasat of Carlsbad, California, modified its design for a medium-Earth-orbit constellation that would consist of 20 telecom satellites instead of 24 as originally envisioned, the FCC said Nov. 2."

The smaller constellation would orbit in four orbital pathways in 8,200-kilometer orbits, with five satellites per pathway"

"Viasat is one of several operators to have modified its constellation plans since 2016. The new approvals SpaceX is seeking cover an additional 7,518 satellites in V-band, a rarely used spectrum.

Telesat wants to double its approval, adding another 117 satellites that, like SpaceX, would use V-band spectrum.

OneWeb also asked the FCC to OK 1,200 more satellites in March, although its new request has not yet been scheduled for a vote. "

Viasat’s Dankberg explains medium Earth orbit thinking, global expansion strategy - SpaceNews.com Aug 2018
"Viasat is still working on a medium-Earth-orbit satellite constellation idea revealed almost two years ago, but has not finalized what that system would look like, Mark Dankberg, CEO of Viasat, said Aug. 9. Viasat is “putting a bunch of work” into optimizing a 24-satellite system disclosed in a 2016 application to the U.S. Federal Communications Commission that would provide connectivity using Ka-band and the lesser used V-band spectrum. "

“The direction we’ve been looking at is really looking at the non-GEO and the GEO as an integrated system, and that relieves that constraint. We don’t have to use the non-GEO to provide coverage everywhere.”

Viasat’s approach to globalization is to “really understand each market and be able to deliver services to end users in those markets, not just sell to intermediaries,” [Mark Dankberg] said.

FCC grants Telesat LEO market access despite ViaSat protests - SpaceNews.com
"Following 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.
Competitor and partner ViaSat of Carlsbad, California, which operates geostationary satellites and is awaiting FCC approval for a medium-Earth orbit system, had urged the FCC to deny Telesat’s filing, but was largely rebuffed."

"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."

"Telesat plans to select a manufacturer for its constellation next year, and start launching in 2020, leading up to activation in 2021. The full constellation will support broadband communications with several terabits of total capacity."

"The FCC did include conditions on Telesat, such as a need to clarify space debris mitigation as the constellation progresses. . . . OneWeb and Spire both took up space situational awareness issues about Telesat LEO with the FCC. "

ViaSat, Intelsat, OneWeb cite access to spectrum as big concern | FierceWireless Oct 2017
"Asked about the major factors affecting investment in next-generation satellite technology, several leading satellite players said access to spectrum is the No. 1 issue. Executives from ViaSat, Intelsat and OneWeb testified Wednesday during a U.S. Senate Committee on Commerce, Science and Transportation hearing"

"Another related area: unlicensed spectrum. The business model changes dramatically when unlicensed spectrum is made available. In Africa, ViaSat needs to go through cellular operators to provide service, but the cell equipment costs thousands of dollars. In Mexico, it’s able to go directly with its own satellites and put in a Wi-Fi hotspot for $1,000, so seeing regulations to support those kinds of models would be very helpful, Dankberg said."

"As more satellites are launched, the potential for collisions rises, and OneWeb’s Wyler stressed that a more formal process needs to be created to prevent catastrophe in space."

MSS: Inmarsat failed to meet required milestones, says ViaSat | PolicyTracker: Nov 2017
"Inmarsat was one of two companies granted spectrum for mobile satellite services by a European Commission decision in 2009. The original expectation was that this would be used for mobile TV, other multimedia services or rural broadband services but it is now being used in an emerging new market: onboard WiFi for aircraft. The Commission decision was controversial because it allowed operators to use complementary ground components (CGCs) – terrestrial base stations – as part of their satellite network."

Inmarsat On Track With EAN Roll-Out, Despite Challenges | Aviation Week Oct 2017
"Inmarsat still expects the European Aviation Network (EAN) to be operational by the end of the year, despite an attempt by rival satellite operators to block it. "

"Inmarsat and telecommunications company Deutsche Telekom are developing the broadband offering, which uses both satellite and Long-Term Evolution (LTE)-based ground networks to provide high-speed inflight internet over Europe. International Airlines Group (IAG) became the launch customer for the service in March, and has indicated plans to equip more than 300 of its airlines’ aircraft to use it."

"But two other satellite companies are asking regulators to stop the EAN roll-out, claiming Inmarsat is misusing its grant of 2GHz spectrum by primarily deploying an air-to-ground network.
California-based ViaSat filed a complaint against the European Commission (EC) in April, which Eutelsat joined in July. The two companies have a partnership to offer broadband services in the European market."

From Boeing to SpaceX: 11 companies looking to shake up the satellite space | FierceWireless
"Companies filed with the FCC last year to launch 8,731 non-geostationary orbit (NGSO) communications satellites, according to Parabolic Arc. Not all of them are proposing to connect the unconnected to the internet; some are geared toward IoT and others are looking at serving the space industry. Performance is expected to be far better than previous satellite generations, with fiberlike speeds and lower latency."

ViaSat expects ViaSat-2 to make it more competitive with cellular’s ‘unlimited’ offerings | FierceWireless, June 2017
ViaSat, a recent member of the Dynamic Spectrum Alliance, has been at odds with CTIA for some time in the FCC’s Spectrum Frontiers proceeding. For example, ViaSat explained in an April 28 FCC filing that it expressly opposed CTIA’s call for “moving forward” with making the 40-42 GHz, 47.2-50.2 GHz and 50.4-52.4 GHz band segments available for licensed, terrestrial service. Similarly, it opposed creating a contiguous 5.5 gigahertz block of spectrum for terrestrial applications by “eliminating the longstanding primary designations of the majority of this spectrum for satellite operations.”

Low Earth Orbit Constellations Could Pose Interference Risk to GEO Satellites, Oct 2015
"A proposed wave of low Earth orbit communications satellite constellations could become an interference hazard for satellites in geostationary orbit even if those new systems comply with existing rules, some satellite operators fear."

"[Daryl Hunter, senior director of regulatory affairs for ViaSat]said that problem could be exacerbated if a number of the proposed NGSO satellite systems are launched over the next several years. If some of them violate the ITU rules, he said, it could be difficult to determine which ones are causing the excess interference."

Meet The World’s Most Advanced Telecom Satellite | Aviation Week Apr 2017
"ViaSat-1 was a technical marvel when it entered service over North America five years ago, with 10 times the capacity of any Ka-band satellite previously launched. But its beams filled up quickly. Boeing-built ViaSat-2, which was supposed to launch from Kourou on April 25, will have a throughput of 300 Gbps, offering more than double the capacity and seven times the coverage area of ViaSat-1."

"And as it prepares for the $600 million ViaSat-2 to come online later this year, the company already has embarked on an ambitious development of ViaSat-3, a family of three 1,000-Gbps satellites aimed at taking its network global by the early 2020s."

"EchoStar’s HughesNet, a competing satellite-based broadband service, serves more than one million households. Its network capacity more than doubled with the December 2016 launch of EchoStar XIX—now the world’s highest-capacity satellite—on a United Launch Alliance Atlas V. While Viasat-2 will have even more capacity, its rival has a head start of six months. "

"the OneWeb startup is aiming to provide internet access to rural areas and the developing world via a constellation of 648 small satellites. "
