Soyuz launch completes first-generation O3b constellation - SpaceNews.com Apr 2019
"European launch provider Arianespace completed SES’s first-generation O3b constellation April 4 [2019] with the Soyuz launch of four satellites."

"SES now has 20 O3b satellites in medium Earth orbit. Franco-Italian manufacturer Thales Alenia Space built the Ka-band satellites, each of which carries 20 gigabits per second of throughput. "

"John-Paul Hemingway, SES Networks CEO, stood by SES’s decision to focus on medium Earth orbit, arguing that low Earth orbit systems will face latency challenges similar to GEO satellites because their closer proximity to the Earth means smaller coverage areas, necessitating routing traffic through multiple stops for long-distance communications. "

Satellite antenna companies divided on near-term feasibility of cheap flat panels - SpaceNews.com Oct 2018
"Builders of satellite antennas disagree on whether flat panel antennas — widely considered a necessity for planned broadband megaconstellations — can be produced cheaply enough to address the mass consumer market in the near term. Antenna makers say so much enthusiasm exists for such antennas that sorting fact from wishful thinking among buyer expectations and seller claims has become a difficulty all its own. "

"“We’ve all heard the crazy requests from some operators asking for millions of antennas for multiple hundreds of dollars,” said Drew Klein, director of international business development at C-Com Satellite Systems, a company that builds dish antennas and is working on a flat panel antenna with the University of Waterloo. Such prices are achievable “within the next decade” — and have to be, he said, in order to address new markets. "

"Some antenna companies, like Israel-based Gilat Satellite Networks, are focused first on building flat panel antennas for customers who are willing to pay higher prices than consumers. "

“I think we are a long ways away from seeing a consumer flat panel antenna in the couple-of-hundred-dollars price point, which is where it needs to be to compete with consumer terminals that we have today for [high-throughput] satellites,” said Andre Jones

"In the absence of commercial flat panel antennas, SES has been forced to rely on two dish antenna systems with mechanical steering to keep constant links with O3b satellites in 8,000-kilometer medium Earth orbits, but this approach is very expensive. "

"John Finney, Isotropic CEO, said his company is making progress on an antenna designed to fit within a $300 to $700 price range stipulated by OneWeb"

"Kymeta antennas are priced up to $39,000 today, though the company plans to drive those prices down to below $1,000 through volume."

Antenna builder ThinKom makes push for constellation market - SpaceNews.com Oct 2018
"ThinKom tested a phased array antenna with SES in August, practicing links with O3b satellites in medium Earth orbit as they rose over the horizon and then tracking them for 30 minutes each.

"Last month, ThinKom and Telesat announced plans to test an antenna with a Telesat prototype satellite in low Earth orbit (LEO) and to collaborate on business-grade terminals for Telesat’s planned 120-satellite LEO constellation. "

"The absence of such flat-panel antennas, as constellations start launching and high-throughput geostationary satellites grow in number, has satellite operators “all pretty much desperate to see somebody bring a solution to market,” according to Chris Quilty, president of Quilty Analytics. "

"ThinKom is best known for its ThinAir Ku3030 antennas that inflight connectivity provider Gogo builds into its 2Ku airplane Wi-Fi terminals. ... Bill Milroy, ThinKom’s chairman and chief technical officer, said his company intends to use the same phased array technology it has used for antennas on aircraft "

"SES is attempting to cultivate commercially viable flat-panel antennas for O3b mPower, its next-generation constellation, having contracted with Viasat, Alcan Systems and Isotropic Systems last year to build electronically steered antennas. "

"ThinKom’s approach differs from SES’s other three partners in that its antennas don’t use electronic steering, despite being relatively flat. The aeronautical antenna it is testing with SES is 20 centimeters thick and uses mechanical systems to track satellites. "

"Whereas a ThinKom antenna requires around half a second to switch satellites, an electronically steered antenna has the potential to switch in microseconds"

"ThinKom is targeting $10,000 for enterprise, or business-grade, terminals. ... For consumer terminals, ThinKom is targeting “sub-$1,000” prices."

Insight-as-a-Service for Satellite Networks - NSR Sep 2018
"The terrestrial telecom industry is fast shifting towards 5G networks, with Software Defined Networks (SDN) and Network Functions Virtualization (NFV) forming key parts of major strategic efforts. This is seen in multiple market movements where organizations such as Verizon, AT&T and Ericsson have begun to shift towards adopting SDN/NFV approaches to manage increasingly complex networks. But what does this mean for satellite players, and how can they remain competitive?

With satellite operators beginning to unlock value behind pixels and bits, the industry is moving downstream towards a data-driven application business. Earth Observation (EO) and Machine-to-Machine (M2M) / Internet-of-Things (IoT) satcom stand at an inflection point. While most of the opportunity will remain in the application layer, a parallel story is emerging in the network layer as well."

"NSR’s Big Data Analytics via Satellite, 2nd Edition report establishes the revenue potential for satellite big data lies largely in the Transportation, Gov/Mil and Energy markets."

"A major driving force of this growth is the increasing complexity of networks."

"... in late 2017, SES used dynamic bandwidth allocation based on SDN principles on its O3b fleet."

MEO startup Methera plans “high density” HTS constellation - SpaceNews.com aug 2018
"In medium Earth orbit, the only system providing satellite broadband today is SES Networks’ constellation of 16 O3b satellites. A British startup with its own 16-satellite constellation idea wants to change that. Methera Global Communications estimates it needs $500 million to build and launch a constellation of satellites each equipped with 40 gigabits of capacity to beam down Ka-band connectivity to highly concentrated areas. If successful, Methera will launch its first spacecraft in 2022, with service starting that same year."

" “Instead of trying to put a thin veneer of coverage around the globe, what we’re doing is looking at a small number of targets where we will put lots of capacity,” [CEO Chris McIntosh] said. Methera’s 700-kilogram satellites — the same mass as the first-generation O3b satellites — will hone capacity on extremely specific locations, targeting a small number of high-value customers "

"But positioning the satellites in medium Earth orbit means customers of Methera’s system will need advanced antennas that can track the satellites as they move relative to the Earth’s surface. ... O3b faced the same challenge and, finding flat panel, electronically steerable antennas commercially unavailable, started service in 2014 with terminals using two dishes ensuring a constant link for uninterrupted service. ... Methera is focusing initially on parabolic antennas as well"

"Methera has a pending application with the U.K.’s telecom regulator Ofcom to license its low-latency satellite system, McIntosh said. The company has not applied for market access in the U.S. with the Federal Communications Commission because the U.S. is not an area of initial focus, he said. "

Enabling a GEO-NGEO Hybrid System - Northern Sky Research, Jul 2018
"The Military segment has, historically, primarily been served by GEO satellites for execution of critical applications, including intelligence gathering, navigation and communication. GEO systems, by nature, offer the advantage of significant coverage via a single satellite, especially with the advent of GEO-HTS satellites. On the other hand, latency and significant CAPEX have always been limitations of the GEO architecture. These drawbacks have given rise to the emerging trend of LEO and MEO constellations (NGEO) that can offer low latency and lower cost per satellite. However, constellations have their own set of constraints, with system complexity, ground infrastructure costs and frequency spectrum coordination, to name a few. Considering both, the shortcomings as well as the strengths of each system, could this perhaps be the start of an integration between GEO and LEO/MEO operators with a hybrid GEO-NGEO system on the rise? "

"Keeping the overall system costs low, however, is where it gets complex for NGEO framework. Although the manufacturing and launch costs per satellite are relatively lower, the need for a considerable number of satellites, the associated replenishment costs and the ground infrastructure expenses – all intensify the overall system cost."

"NSR estimates just over 1% of total revenues for gov/military will come from Non-GEO constellations by 2027."

"[TCO] is a key driver for NGEO constellations, military and otherwise, and is as well one of the biggest challenges for the operators presently. Simply put, either the expenses, mostly CAPEX, need to drop or the revenues need to grow for the business case to sustain. This is where a GEO-NGEO Hybrid architecture could prove pragmatic."

"Intelsat’s and OneWeb’s unsuccessful attempt towards a strategic alliance was one example of this hybrid system. GEO operators JSAT and Hispasat have similarly announced strategic investment in LEO constellations including LeoSat."

"Another level of integration, perhaps more technically innovative, and therefore challenging, is a system where GEO satellites can handle the TT&C operations for LEO constellations and act as the base station control system of the network."

FCC Issues Inter-Satellite Data Relay Network License to Audacy; Non-GEO Market Access to O3b - Via Satellite - June 2018
The U.S. Federal Communications Commission (FCC) has granted a license to Audacy that authorizes the space communications company operate the world’s first commercial inter-satellite data relay network.

The data relay network will utilize two ground stations, in San Francisco and Singapore, as well as three Medium Earth Orbit (MEO) satellites scheduled to launch in 2019. With this network, Audacy hopes the spectrum will be able to provide real-time downlink, continuous monitoring, and always-on command services to Low Earth Orbit (LEO) spacecraft.

Along with the Audacy license, the FCC has also granted O3b’s request to modify its existing U.S. market access grant by adding new non-geostationary satellites and new frequency bands to provide broadband communication services in the U.S.

Sabbagh: SES is a “Lonely Voice” in the Industry | Via Satellite, Jan 2018
SES was the talk of World Satellite Business Week (WSBW) late last year when it announced a major new strategic initiative, mPower, through O3b. SES has contracted with Boeing Satellite Systems, to build seven super-powered Medium Earth Orbit (MEO) satellites. The constellation will have 30,000 fully-shapeable and steerable beams that can be shifted and switched in real time to align with customers’ quickly changing growth opportunities.

... You have to remember that O3b was initially designed to provide very high throughput to a small number of clients each with very high bandwidth requirements. The evolution we were looking for was one where we could further advance the throughput performance while achieving greater flexibility and scalability on the bandwidth in order to serve and empower a much larger market.

... The first seven satellites of the new system will bring multi-terabits of productivity. We can scale this up as we add new assets into the constellation.

VIA SATELLITE: Has the industry been slow to change?

Sabbagh: The answer is yes, and it is the predicament of every industry where there is a well-established playbook that yields rich economic returns.

FCC gets five new applications for non-geostationary satellite constellations - SpaceNews.com March 2017
Boeing: “1,396 to 2,956 low-Earth orbit (LEO) satellites for providing connectivity”

SpaceX: VLEO, “V-band low-Earth orbit (LEO) constellation of 7,518 satellites to follow the operator’s initially proposed 4,425 satellites that would function in Ka- and Ku-band”

Telesat: “V-band LEO constellation as one that “will follow closely the design of the Ka-band LEO Constellation,” also using 117 satellites (not counting spares) as a second-generation overlay.”

Theia: “use V-band frequencies for gateways on the ground that would have originally only used Ka-band. The company wants to operate a constellation of satellites for both communications and remote sensing, and claims that because its spacecraft will have “regenerative” payloads, that “there is no specific relationship between V-band uplink frequency bands and downlink frequency bands.””

OneWeb: “operate a “sub-constellation” of 720 LEO V-band satellites at 1,200 kilometers, and another constellation in Medium Earth Orbit (MEO) of 1,280 satellites. Added together, that expands the OneWeb constellation by 2,000 satellites”

O3b: “up to 24 additional satellites that would operate in a circular equatorial orbit as a constellation called O3bN”

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."
