Atheras Analytics Extends Capabilities of Its SaaS-Based Software Tools

Atheras Analytics has developed a suite of SaaS-based software tools that enables satellite operators to optimize the design and operation of their next-generation Ka-band and Q/V-band satellite networks by taking into account region-specific weather conditions – in particular rainfall.

The core of these tools is an AI-based Outage Prediction Algorithm (OPA) that was developed by STFC RAL Space inventor, Dr. Spiros Ventouras, based on ESA-funded research into atmospheric attenuation of Ka-band and Q/V-band satellite links, which were taken across Europe over several years. The OPA employs advanced machine learning techniques, including neural networks, to “train” it for multiple different operational scenarios.

John Yates, Atheras’ managing director, explained: “This funding will enable us to support the many new innovative satellite constellations coming on-line in the near future offering ubiquitous high-speed Internet service to business and consumers worldwide. It will help us to accelerate the development of our toolkit and extend the capabilities of the OPA into exciting new growth areas, such as the rapidly evolving Low Earth Orbit and Medium Earth Orbit satellite constellations and optical satellite links.”

The satellite telecommunications sector is about to enter a phase of major change in the delivery of ubiquitous consumer and enterprise broadband through the use of High Throughput Satellites (HTS) and Very High Throughput Satellites (VHTS), which can deliver more than 20 x the data capacity of traditional satellites at a fraction of the cost. Employing higher frequency Ka-bands and Q/V-bands is necessary to support these higher data rates. However, because these higher frequency bands are much more susceptible to atmospheric impairments than those previously used, the work of Atheras Analytics is essential to support this shift in broadband delivery.

Hughes Network Systems, OneWeb Ink Deal

Hughes Network Systems and OneWeb have inked a capacity deal for its customers in two agreements – one with the United States, the other with India, according to a statement from Hughes. The U.S. distribution agreement  focuses on enterprise services, and the companies have reached a memorandum of understanding to distribute services in India to large enterprises, government, telcos and internet service providers in the rural and remote parts of the country, Hughes said.

Services will be offered in the United States by Hughes Network Systems and in India by Hughes Communications India Private. Hughes President Pradman Kaul said at a press event that the company’s joint venture with Bharti Airtel in India is expected to close later this year, according to a report published by Satellite Show Daily.

This action will combine Hughes Geostationary Orbit (GEO) satellites and network technologies with OneWeb’s satellites in low-Earth orbit (LEO). Satellite Show Daily said that the companies shared a demonstration on Sept. 9 of this multi-orbit connectivity. It showed Hughes ActiveTechnologies software transmitting different types of traffic, such as streaming and gaming, over the most efficient path, whether it be OneWeb or Jupiter HTS.

“The future of connectivity depends on a worldwide network of multiple transports, including terrestrial, geostationary and low-Earth orbit satellite services,” Kaul said in a prepared statement. “OneWeb’s system enhances the Hughes portfolio of networking capabilities, introducing a low-latency option with global reach that complements GEO satellite capacity density and capability to meet our customers’ needs.”

 

U.S. Navy Awards L3Harris Contract For 16 COMSATCOM Terminals

By The Editors of AGL

The U.S. Navy has awarded L3Harris $18 million as part of the Commercial Broadband Satellite Program (CBSP), a continuing effort to bolster sailors’ access to commercial broadband communications while on active maritime duty.

The company’s long-standing commitment to the program and on-time delivery of the systems led to four additional units being added to this year’s contracted activities.

CBSP provides terminal-to-shore, space, and terrestrial connectivity, increasing throughput for commercial satellite communications to provide redundancy for military satellite communications. The program includes two U.S. Navy contracts for separate types of terminals, one for Force-Level Variants (FLV) and another for Unit-Level Variants (ULV).

The ULV contract is a 10 year, indefinite delivery, indefinite quantity award, through which the Navy has deployed more than 150 systems to date. This year’s award will provide the service with 16 new units; work is expected to be completed later this year.

CBSP is used as a secondary service for communications that do not leverage the Advanced Extremely High Frequency Naval Maritime Terminal (NMT). It is also the backup for the NMT if it is unavailable,

Lynk Files for FCC License to Employ ‘Cell Towers in Space’ Next Year

Lynk Global, said to be the world’s sole independently verified space-based mobile network connectivity provider, has announced that it has filed for a commercial operator’s license with the FCC. Commercial service is expected to begin around the world starting next year upon FCC approval.

The startup expects its patented technology to eventually allow anyone with an existing cellphone to stay connected, anywhere in the world, at all times. Furthermore, Lynk’s system requires no changes to the phone; any common cell phone will work.

“Lynk is introducing a brand-new, never-been-done-before service — satellite-direct-to-standard-phones,” said Charles Miller, CEO of Lynk. “As an American company, we are fortunate to have the FCC, whose process is trusted by officials around the world, to license our satellites. We believe that being good corporate citizens means at every point in the process you must be rigorous—whether it is eliminating harmful interference or minimizing orbital debris. Because using cellular frequencies from space has never been done before, we believe that being licensed by the FCC will help regulators worldwide embrace this groundbreaking technology.”

Lynk’s initial commercial license application intentionally uses the FCC’s new streamlined process for up to 10 small satellites to accelerate granting the license. Experience with previous applications suggests this streamlined process will take 10-12 months, allowing Lynk to begin global service next year. This is the first step in Lynk’s plans for a larger constellation that will grow to several thousand satellites to begin continuous global service in 2025.

Ultimately, Lynk plans its full constellation to reach 5,000 satellites to provide broadband speeds to your phone. Using a low-risk development approach, the company will integrate some of today’s most advanced space sustainability methods to prevent and mitigate orbital debris, and Lynk is actively advocating within industry and government to develop stronger orbital debris mitigation approaches.

In February 2020, with the help of NASA and mobile network operators (MNOs), Lynk sent the world’s first text message from a satellite in orbit to a standard mobile phone on the ground. Lynk has also signed contracts with the U.S. Air Force and the UK Space Agency to support development of its system.

To date, Lynk has signed dozens of testing agreements with MNOs. Miller noted, “There is a huge amount of interest in Lynk’s service … we actually have too many testing partners at this time. To manage this demand and ensure the highest quality testing protocols and commercial service, we are implementing a ‘Flagship Carrier’ program. Under this program, we will be limiting initial commercial services to, at most, a dozen mobile network operators globally.”

In partnership with mobile network operators, Lynk will provide a service for the 5.2 billion existing cell phone users globally. Further, many of the 2.5 billion people currently without phones will be connected to the global society and economy, materially improving their lives. Lynk will provide an instantaneous backup emergency communications layer everywhere on Earth. Lynk will enable people to receive emergency alerts and contact 911 for help even when the ground network is not operating due to hurricanes, earthquakes, wildfires and terrorism.

Facebook Getting into the MM Wave Fray

July 6, 2016 — Facebook, of all entities, has come in on the side of the players that are telling the satellite industry to share the wealth. In an ex parte presentation, Facebook said it supports sharing of both users and satellite operators within the new 28, 37 and 39 GHz upper microwave, flexible-use bands. They believe that the degree of sharing will allow for the coexistence of satellite earth stations without harm to mobile deployments in those bands.

Well, I have a hard time giving Facebook any credit for having any idea of the wireless business and the complexities that occur when multiple users and platforms vie for peaceful coexistence.

To wit, they are lobbying for more use of spectrum access systems and related technologies, which enable better frequency utilization, thusly improved sharing and management of spectrum. While this sounds great in theory, such practices haven’t even been proven in the 3.5 GHz band yet. And most operators aren’t going to warm to the idea until that happens.

Wonder what Facebook is thinking? Could it be that they are taking a page out of Google’s philosophy to become a player in such platforms as remotely piloted, high-altitude, solar-powered unmanned aircraft (HAPS) or innovative new terrestrial wireless systems that will be a part of the 5G ecosystem, especially for rural and remote areas?

Whatever the reasons, you can bet it won’t be for the betterment of connectivity without something being in it for them.
