LeoSat, absent investors, shuts down - SpaceNews.com Nov 2019
"LeoSat, a company that was seeking to operate a constellation of 78 to 108 satellites for high-speed internet, has suspended operations due to a lack of investment. "

"LeoSat was anticipating that Spanish satellite operator Hispasat and Sky Perfect Jsat of Japan would complete LeoSat’s $50 million Series A after each made initial investments — Jsat in 2017, Hispasat in 2018 — but neither did."

LEO Survival of the Fittest…or the Smartest? - NSR
"Financial “fitness” can be thought of as the funding – either self or outside – that is essential for breaking the barriers to entry and for survival in the short-term. “Smartness” can be considered as the right target market, pricing strategy, capability and repeatability to ensure long-term sustainability. So, when it comes to LEO HTS Constellation survival, what is the answer to the question: Fit or smart?"

"A grand total of almost $48 B [in capex] must be invested to deploy all constellations as they are currently planned."

"From this assessment, based on the funding status and CAPEX to funding ratio, OneWeb is the “fittest” player today. That said, even though Amazon does not have any announced funding at this stage, NSR believes their deep pockets ensure that this will not be a challenge in the launch of Project Kuiper."

"... revenue estimates are a different game altogether. NSR forecasts $43.6B in overall Non-GEO revenues over the 2018 – 2028 period. "

"To compensate for higher than anticipated expenses during the early stages, OneWeb has shifted their short -term priority towards higher revenue generating applications. "

"As one of the biggest constellations planned, SpaceX’s constellation is also associated with the highest expenses. With over $1B in funding raised so far, it makes up a mere 7% of the total estimated CAPEX. ... Starlink’s architecture does allow SpaceX to offer high speed Internet to markets with high price tolerance. But will the market size be big enough to support SpaceX’s long-term plans?"

"The latest news from Telesat indicates it will hedge its bets with a hybrid architecture."

"Short-term “fitness” remains the biggest question for LeoSat as they work towards lowering the overall system CAPEX."

LeoSat and partners put satellites on a diet - SpaceNews.com Oct 2018
"“If we can get the number of required launches down from 14 to seven or from 12 to six, we could make savings that take the $3.5 billion plus down to close to $3 billion,” Rigolle said. “If the per unit cost of building the satellites could be pushed down by a few million a piece, it chips at the cost and improves the total viability of the project.”"

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."

OneWeb says regulatory concerns main reason it’s forgoing inter-satellite links - SpaceNews.com Jul 2018
"Among the major new privately financed satellite broadband constellations, OneWeb stands alone in not planning to feature inter-satellite links on its spacecraft.

Greg Wyler, OneWeb’s founder, told SpaceNews the reason his constellation of 900 or more low Earth orbit satellites won’t include inter-satellite links is because national regulators have expressed concerns about where traffic from their country will travel and where it will come back down to Earth. "

"Not everyone agrees with Wyler’s view. Erwin Hudson, vice president of Telesat LEO, said Telesat is prepared to address sovereignty concerns nations have on a case-by-case basis."

"Wyler said regulators are concerned about eavesdropping and manipulation of their country’s data. The “fundamental problem” with inter-satellite links, he said, is that once traffic goes up, “you have no idea whether it is being copied and sent to a secondary location.”"

July 2018 - Evolutionary Antenna Tech Inspires the Future of Satellite Constellations | Via Satellite June 2018
"Following seven years of development, Phasor’s electronically steered antennas began testing in commercial use cases this year. These antennas are barely 2.5 centimeters thick, and are designed to be conformal in order to look at a wider angle 180 degrees, with dual-beam technology making them LEO and GEO interoperable."

"LeoSat, for example, sees itself as a disruptor in the defense market — which has traditionally relied upon GEO systems."

"By their own admission, Phasor will never be at the bottom of the food chain. And, while the super yachts of the world number in the thousands, fishing boats number in the millions"

"Isotropic Systems aims to be one of the leaders working to connect smaller maritime vessels and flight routes in India, Africa and Latin America. One way to achieve that, they believe, is by reducing the price point of terminal systems by 70 to 90 percent."

LeoSat's Rigolle: Fundraising Big Focus this Year - Via Satellite - Mar 2018
"NewSpace startup LeoSat, which is building the satellite equivalent of a Virtual Private Network (VPN) in space, plans to focus primarily on raising funds for its Series A round this year. With a glut of major customer agreements already signed, the company’s next hurdle is ensuring it has enough cash on hand to build out its full constellation by 2022, said LeoSat Chief Executive Officer (CEO) Mark Rigolle in an interview with Via Satellite."

"LeoSat also recently signed an agreement with Phasor to develop a Ka-band version of its low-profile Electronically Steered Antenna (ESA). While a traditional mechanized dish will be sufficient for the majority of the company’s services, ESAs could unlock new applications and customer bases, Rigolle said, pointing to embassy networks as an example."

Megaconstellations: Recipe for Disaster or Biggest Opportunity Yet? | Via Satellite, April 2018
"within this enthusiasm for large, powerful LEO constellations and the applications they’ll deliver, the voices of caution are growing louder, tempering much of the fervor around pushing fleets of fresh satellites into the skies. Some of the biggest concerns orbit around the topic of space debris"

"Since 2014, space industry consulting firm Northern Sky Research (NSR) has tracked $2.1 billion in investments for broadband megaconstellations (such as LeoSat and OneWeb), plus an additional $1.5 billion in SpaceX. Additionally, since 2016, NSR has tracked $23.7 million invested in satellite Internet of Things (IOT) startups. "

"Over the last several years, the company has spent more than $3 billion on a massive undertaking — refreshing the company’s existing fleet of satellites with a new constellation known as Iridium Next, an architecture consisting of 66 small, interconnected mobile satellites (plus nine on-orbit spares and six ground spares), which will reportedly cover 100 percent of the Earth’s surface, including oceans and polar regions. "

"One of the younger companies in this space, LeoSat Enterprises, is positioning itself as filling the space between traditional satellite and fiber-optic networks."

"But while LEO possesses latency advantages, Steve Collar [SES O3b mPower] says the cost of deployment is too prohibitive. SES plans to launch seven next-generation MEO satellites in 2021"

"The University of Southampton's debris simulation model, Debris Analysis and Monitoring Architecture to the GEO Environment (DAMAGE), offers scientists a glimpse of the worst-case scenario — whereupon a hypothetical large constellation operator disregards existing space debris mitigation guidelines, leading to series of collisions."

"While international guidelines currently recommend that operators remove spacecraft from LEO within 25 years of the end of the life of the spacecraft, Holger Krag [ESA's Space Debris Office] reportedly told attendees at 2017’s European Conference on Space Debris that only 60 percent of operators actually do that."

"a growing number of startups whose business case is based on their power to mitigate debris [e.g. Singapore-based Astroscale] raised $25 million [in 2017, for a] total raise to $53 million"

March 2018 - LEO/MEO Satellites Poised to Make a Mark in Military Sector | Via Satellite
"Satellites in LEO and MEO soon will be here to stay thanks to companies like LeoSat, OneWeb, and SES-owned O3b. The question is whether they also can go beyond meeting the needs of commercial and consumer users to also serving the needs of a dispersed, increasingly mobile military. Via Satellite talks to leading LEO and MEO industry figures to see how they envision their constellations supporting military missions globally in a fast-evolving threat environment."

"The United States Defense Information Systems Agency’s (DISA) recent Request for Information (RFI) calling for a low-latency satellite connectivity solution underscores the government’s openness for considering new non-Geosynchronous Earth Orbit (GEO) solutions. And that cooperative posture also has been illustrated during the Air Force’s wideband Analysis of Alternatives (AoA) exercise to define the future space architecture, where several LEO and MEO companies put forth their recommendations."

"LeoSat is on schedule to launch two demonstration satellites in the second half of 2019. Launch of the production satellites will begin in late 2020 and the constellation should be complete by 2022." LeoSat's Abad: “We are not looking to bring broadband down to every single person in the world. We want to provide carrier-grade telecommunications services via space.”

"Both LeoSat and OneWeb have received high-profile funding — SKY Perfect JSAT became an anchor investor in LeoSat in May, while OneWeb received $1 billion from Japan’s SoftBank last December, making it a 20 percent equity owner. OneWeb also has partnered with Airbus on its new high-volume production facility in Exploration Park, Florida."

“What needs to change is the ground infrastructure — you can’t build a LEO constellation realistically with two parabolic antennas and expect to reach the scale and volume that these providers talk about,” says Brad Grady, senior analyst in Northern Sky Research’s (NSR)

"NSR estimates that the defense sector will require about 14 gigabits per second of non-GEO HTS capacity demand by 2025, representing an 18 percent annual growth rate from 2015."

“Everyone has figured out that the critical point in launching these new constellations is the antenna system. You can’t have a successful non-GEO network without a very agile, very capable antenna technology,” says David Helfgott, CEO of Phasor, one of a handful of antenna technology providers who will plan to offer Commercial-Off-the-Shelf (COTS) antenna solutions for these up-and-coming constellations in the next 12 to 36 months.

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."
