LOGAN, Utah -- Alta Devices is scaling up solar production to meet growing demand for small satellites (SmallSats). Tens of thousands of low-earth orbiting (LEO) SmallSats are expected to be launched over the next decade. They will all rely on the sun for power. Alta Devices solar material has the potential to meet the specific needs of this SmallSat boom.
Solar is the single most expensive hardware component in a small satellite. Alta Devices has developed proprietary equipment to mass produce its thin film gallium arsenide. This equipment is being scaled up to produce at much higher volumes and lower cost than other space solar manufacturers. Alta's ability to produce at this scale is unique and can substantially lower the cost of each SmallSat.
Furthermore, Alta Devices flexible solar cells provide a new level of mechanical and design flexibility for the satellite industry. Alta’s technology can be mounted to thin, flexible, low-mass deployable structures allowing creative design approaches to maximizing the solar array. These include coiled carbon fiber booms, flat-packed, polymer-based accordioned arrays, or even inflatable structures. This allows more compact design of the high-power solar arrays required to power high-speed LEO communication satellites.
Finally, traditional photovoltaic assemblies (PVAs) are composed of hundreds or thousands of small solar cells, each protected with a tile of glass, connected to each other through individual metallic welds, which are then carefully grouted to prevent electrical arcing and attack from the space environment. In contrast, Alta’s space product will consist of flexible, glass-free units that are 10 to 100 times larger, thus eliminating breakage, lowering cost and having no exposed electrical interconnects. Alta’s space product will enable bonding to customer substrates using a large-area, high-volume vacuum bonding process, as opposed to mounting individual cells or CICs (Coverglass Interconnected Cells).
Overall, Alta’s goal is to provide LEO satellite manufacturers with a better balance of solar conversion efficiency, reduced array weight, cell durability, speed of deployment, and cost compared with conventional space solar cells.
The small satellite market for LEO constellations
According to filings disclosed by the Federal Communications Commission, over 15,000 LEO SmallSats are planned for deployment soon. The applications of these satellites include communications, scientific research, military intelligence, remote sensing, and new technology development.
Over the coming years, Alta Devices plans to produce tens of megawatts of solar. Manufacturing will take place at Alta Devices corporate facility in Sunnyvale, California and at an international manufacturing facility. In April this year, Alta Devices solar was used on a successful mission to power over 60 ThinSats launched from the NASA Wallops Flight Facility in Virginia. Alta Devices is working with top satellite manufacturers for the deployment of its technology on several upcoming launches.
Said Alta Devices CEO Jian Ding: “Now we are established in the HALE UAV/HAPS market, we are committed to enabling LEO satellite projects with our unique technology. We believe our solution will meet the needs of this fast-growing market.”
On Jan. 23, Broadband World News hosts a Calix-sponsored webinar that explores several ways CSPs can enhance customer experience and find new business opportunities to avoid devolving into a speed race where nobody wins, not even the customer.
The lack of an accurate broadband map means states and counties are tackling this issue themselves – and sometimes finding big disparities in the data – before spending their residents' money on deploying infrastructure.
Next year many operators must decide whether to invest more in HFC or go all-in to fiber, pick their PON and choose their managed-WiFi path, writes analyst Dan Grossman, who also recommends providers bundle managed WiFi and analytics to best serve residential subscribers -- and operators' own businesses.
Public-private partnerships, investor interest, self-help in rural areas and incumbents' return set the scene for a busy year of broadband deployment in the US countryside in 2020, writes Analyst Dan Grossman.
It wasn't long ago that TV was ranked by subscribers as the most important service in the bundle provided by their communications service provider (CSP). Recent research indicates that for nearly three quarters of subscribers, broadband is now the most important service. Broadcast TV is the most important service to only 15% of North American consumers, replaced by OTT video streaming platforms like Netflix, Amazon Prime and Disney+. In addition, many different competitors are moving aggressively to stake a claim in consumers' homes.
In 2020, CSPs need to fight back by transforming their business models, which are becoming more reliant on a single source of revenue: fixed broadband services.
This webinar will focus on helping CSPs transform their business models by placing a firm focus on delivering a sensational subscriber experience and by offering compelling new services that generate value for subscribers. These actions will reinforce the CSP's strategic position in the home network and position themselves for growth in the next decade.
Key topics include:
Being the first to market with WiFi 6 technology, in response to consumer purchases of new devices over the holidays;
Having the insights needed to proactively resolve issues, often before your subscribers even know that there are issues;
Providing help desk agents with the visibility they need to resolve common subscriber issues more quickly;
Delivering a mobile app, in response to consumer demands for the ability to do some things themselves, rather than having to call technical support; and
Addressing consumer concerns around device security, privacy and control with enhanced security and parental controls.
In this insightful Light Reading radio show, Kurt Raaflaub, Head of Strategic Solutions Marketing, will outline the key service provider challenges, deployment considerations, next-gen Gigabit technologies, and service models to win market share in the rapidly growing MDU market.
