With Deepwave Digital, Northrop Grumman is pushing processing to the edge
WASHINGTON — Northrop Grumman says a new investment into small startup Deepwave Digital will allow it to push data processing much closer to the point of collection, decreasing the amount of data that needs to be transported and getting products to war fighters faster.
Northrop Grumman will install Deepwave Digital's artificial intelligence solution on airborne and on orbit payloads, said Chris Daughters, the company's vice president of research, technology and engineering for aeronautics systems. With the AI incorporated into the payload, the satellite or aircraft will no longer need to send data back to the ground to be processed. Instead, the payload will process the data itself.
The innovation, said Daughters, is in incorporating the AI software with the hardware used in various Northrop Grumman payloads.
“Deepwave Digital really has an innovative architecture that blends artificial intelligence with some advanced hardware in the RF [radio frequency] domain, whereas a lot of artificial intelligence in the past has always been focused on, I'll just say, mining and scrubbing really big data or maybe doing customized things with video or audio,” said Daughters.
In other words, the AI is able to process data at the edge, at the point of collection, instead of sending it down to Earth to be processed independently.
“We have a lot of RF payload systems that collect information or collect intelligence for the war fighters and the government as a whole, and by embedding this innovative hardware and AI software, we are able to essentially filter and optimize and scrub and prioritize the data much nearer to the point of collection for that information,” said Daughters.
AI has been key to the military's efforts to manage the torrent of data collected by government and commercial satellites, which is simply too much for human analysts to sort through on their own. While progress has been made in using AI to process satellite imagery, military officials are now tackling a related problem: the sheer amount of raw data being pushed out over the networks for processing at remote locations. To reduce the bandwidth needed for satellite imagery, U.S. Army officials say the military needs to shift to edge processing, meaning applying AI to the data and then sending the finished product out over the network instead of all of the raw data.
“Edge processing is something that we're very interested in for a number of reasons. And what I mean by that is having smart sensors that can not only detect the enemy, [but] identify, characterize and locate, and do all those tasks at the sensor processing,” said John Strycula, director of the Army's task force focused on intelligence, surveillance and reconnaissance, at an October AUSA event.
“If I only have to send back a simple message from the sensor that says the target is here ― here's the location and here's what I saw and here's my percent confidence ― versus sending back the whole image across the network, it reduces those bandwidth requirements,” he added.
Daughters said Northrop Grumman is working to incorporate Deepwave Digital's AI solution into products in development or in limited production in the “very near term.”
“The capability exists now. We just need to integrate it in with the systems,” said Daughters. “Our research and technology organization is already looking at how we could be injecting this hardware and AI capability in some of the systems that exist right now or very near term.”
While the company is applying the AI to both space and airborne systems, the technology can be more easily integrated with airborne systems, where payloads can be more easily accessed or swapped out.

Securing the final frontier: Digital twins, satellites and cybersecurity
Kevin Coggins The United States and our allies are increasingly dependent on unfettered access to space. However, it has become abundantly clear that our space systems have significant cybersecurity vulnerabilities that our adversaries are eager to exploit. Earlier this year, William Akoto wrote about the growing constellations of satellites operated by private industry, led by SpaceX, Blue Origin and others: “If hackers were to take control of these satellites, the consequences could be dire. On the mundane end of scale, hackers could simply shut satellites down, denying access to their services. Hackers could also jam or spoof the signals from satellites, creating havoc for critical infrastructure. This includes electric grids, water networks and transportation systems.” Space Policy Directive 5, recently issued by the White House, notes that “cybersecurity principles and practices that apply to terrestrial systems also apply to space systems” and that we must integrate these principles and practices into every phase of the space system life cycle. SPD-5 is charting the right course toward assuring our cybersecurity in the space domain. This article highlights the unique vulnerabilities of space systems and how innovative solutions like “digital twins” can help us protect systems in orbit today and design more secure ones for the future. Cyberattacks on space systems — comprised of satellites, ground control stations, and user terminals (e.g., GPS receivers) — are appealing to nation-states, criminal groups, hackers and other bad actors. It's a tremendous opportunity to breach data and disrupt operations in a low-risk way with a low cost of execution. The different components that make up space systems each come with their own set of cyber vulnerabilities, the ground segment in particular. Some space systems were built with speed to market rather than cybersecurity in mind. In contrast, for traditional defense-focused space systems, a slower design and development process has introduced vulnerabilities as well. Space systems operating today may have taken a full 20 years to go from paper to launch and lack the capabilities to recognize or respond to today's cyberthreats. Space systems are increasingly interconnected — a malicious attack can easily spread from a single point of vulnerability in a ground station to the satellites. Cybersecurity in space systems has struggled to keep pace with the rapid evolution of threat actors and exploits. Given these challenges, how can organizations with space systems stay ahead of cyberthreats and protect their missions and users? The older approach of paper-based assessments has significant limitations, like the inability to duplicate reactions to all possible scenarios. At the other end of the spectrum, full-scale replicas are expensive and time-consuming to build. In the middle is the “digital twin” concept — a virtual mirror model that synchronizes a physical object with a cyber representation. With this approach, organizations can test a satellite in different scenarios to identify vulnerabilities and develop protection strategies, even before the satellite is built. One specific project that demonstrated digital twins' strengths and capabilities: testing Air Force GPS space systems for vulnerabilities after the passage of Section 1647 of the 2016 National Defense Authorization Act. Starting with a model-based system engineering review of thousands of pages of design documents, we built a digital replica of critical GPS Block IIR satellite components launched between 1987 and 2004 that ran on a single laptop with lightweight applications. Our digital twin created the foundation for a flexible cyber test bed — a suite of scalable software applications to demonstrate and validate cyber vulnerabilities and protection strategies as the system is designed or modified. The test bed can connect with assets beyond the network to generate data, provide war-gaming support and explore attack scenarios. We need this flexibility and functionality for future space system protection. The next generation of satellites will encounter more extreme service conditions and increased, simultaneous cyberattack vectors over longer periods of time. To respond to these challenges, these space systems will need increasingly complex designs, and with such complexity comes potentially greater vulnerability to cyberattacks and threats. Digital twins and model-based system engineering approaches can strengthen security throughout the acquisition and sustainment phases. Use them to: Develop system requirements and analyze design trades. Create test scenarios for requirements clarification and reference systems. Simulate threats, anomalies and impacts without risk to critical infrastructure. Assess the impact of new threats or operational scenarios on an on-orbit system design. What can space system acquisition professionals, developers and operators learn here? Digital twins offer an innovative approach that can streamline and strengthen the testing and design process of our space assets. They can also provide insights on as-built systems and enable the buydown of risks across the space system life cycle, enabling affordability across the entire system life cycle. Now is the time to leverage their capabilities, to ensure that the space infrastructure so vital to our security and American way of life has the protection it requires. https://www.c4isrnet.com/opinion/2020/11/02/securing-the-final-frontier-digital-twins-satellites-and-cybersecurity/

Lockheed offers cash to supply chain, use of private jets for COVID-19 fight
By: Aaron Mehta WASHINGTON — Lockheed Martin, the world's largest defense contractor, announced a series of steps Friday to bolster the defense-industrial base to keep it humming along and to assist in the broader effort against the new coronavirus outbreak. In a statement posted on Lockheed's website, CEO Marillyn Hewson said the company recognizes “that the rapid spread of COVID-19 and its wide-ranging impacts have caused severe disruption across society and tragic loss of life around the world. We also recognize that the global pandemic has created a need for urgent action by government, business, communities and citizens.” “We will do our part to use our know-how, resources, and leadership as a company to assist our communities and our country during this period of national crisis,” Hewson wrote, before laying out a series of moves she called an “initial contribution” to the COVID-19 relief efforts. The company plans to advance “more than $50 million” to small and medium-sized companies in its supply chain to “ensure they have the financial means to continue to operate, sustain jobs and support the economy.” Pentagon officials and outside experts alike have raised concerns about risk to small companies in the supply chain. Lockheed is also dipping into a $6.5 million disaster relief fund to assist employees and retirees who are impacted by the disease, and will donate $10 million to nonprofit organizations involved in outbreak relief efforts, with an emphasis on veteran and military family issues. Additionally, Hewson pledged the use of the company's corporate aircraft and vehicle fleet for the delivery of medical supplies and for logistical support. She also offered the use of company facilities for “crisis-related activities including critical medical supply storage, distribution, and COVID-19 testing, where needed and practical,” as well as the company's technical and engineering skills if states or the federal government require assistance. The company plans to continue recruitment and hiring despite the current economic downturn, using virtual technology and other social distancing tools. Lockheed brought in more than $53.7 billion in revenue in fiscal 2018, 94 percent of which came from defense contracts, according to the annual Defense News Top 100 rankings. https://www.defensenews.com/news/coronavirus/2020/03/27/lockheed-offers-cash-to-supply-chain-use-of-private-jets-for-covid-19-fight
