The private spaceflight company, SpaceX, has undertaken a partner project in addition to its existing space efforts ranging from sending satellites and people to space, to providing a brand of commercial internet connection to remote areas.
The new partner project, Starshield, will join Starlink in providing secure, broadband internet connection to customers. However, there is a stark difference between the partner projects.
Starlink technology has end-to-end user data encryption to secure its network as it was designed for commercial customers. However, the Starshield project is intended for government use in national security efforts. Therefore, it is equipped with an additional high-assurance cryptographic feature to host payloads and process data in a secure way aligning with government national security requirements.
As reported by SpaceX, Starshield has three focus areas including: Earth observation, global communications, and hosted payloads. Starshield’s satellites can integrate with a variety of different payloads and the constellation has a low-Earth orbit (LEO) design making it robust to on-orbit assets.
SpaceX continues to work closely with the United States Department of Defense by providing innovative space technology.

“If this is a problem, the government should act like it.”
Citing more than 10 years of government studies, warnings and promises, representatives from a wide variety of industries criticized the government recently for doing little to address an important national security problem.
At issue was the need for national backup capabilities for GPS and the essential positioning, navigation, and timing (PNT) signals it provides.
GPS signals are weak and easy to block or imitate. At the same time the signals are used by most technologies including networks, telecommunications, electrical grids, broadcast, mobile radios, transportation, and other critical infrastructures.
After Russia threatened to destroy all GPS satellites in 2021 in its run-up to invading Ukraine, a member of the White House National Security Council told a public meeting “GPS is still a single point of failure” for the nation.
The government was criticized for inaction at a “Complementary PNT Roundtable” hosted by the Department of Transportation (DOT) in early August. The department is the federal lead for civil GPS and PNT issues.
Eight attendees interviewed after the event reported a surprising unanimity of comments and concerns expressed by industry reps at the meeting.
Enough with the studies
A repeated theme was that the government has done enough studies to understand the problem and available technologies.
“They have been studying this for over twenty years,” one attendee observed. “The Volpe [Transportation Systems Center] report came out in 2001. And there have been lots of studies since then. All have just been refinements of those original findings.”
Another consistent theme was disdain for the idea that industry and the free market will solve the problem without government leadership and active support.
“GPS is free,” said one attendee from a company that provides PNT services. “We can and do sell to meet niche demands, but it is laughable to suggest we can ever sell enough subscriptions to be enough of a backup for GPS.”
A major telecommunications company rep echoed the sentiment. Wireless telecom is especially reliant on PNT. “We use GPS and would use Loran and low Earth orbit satellites if they were available, but we are not going to build it on our own. There is just no business case.”
“We have a big list of things we could do that would increase our resilience and/or cut costs,” said another telecom provider. “There is no big driver for most, though. No competitive pressure, no government mandates.”
Government must walk the walk
“The government has been telling us for over a decade that this is a problem,” said one attendee. “If that’s true, why aren’t they acting like it? Transportation is critical infrastructure and needs a GPS backup, for example. So why hasn’t DOT done something?” Of all the criticisms expressed, this was predominant, according to interviewees.
A 2021 Executive Order on responsible use of PNT services encouraged critical infrastructure providers to not rely on GPS.
The government needing to be a lead customer was mentioned a number of times at the event. This would help raise awareness, set an example, and signal to users the issue is important enough to act on.
Government action was also seen by users as key to creating confidence that a technology or service will be around for the long haul. This point seemed to resonate with many of the government representatives as well.
“I am not going to go to the time and expense of adopting something unless I know it is going to be around for 20 years or more. The only way I can be assured of that is if one of the biggest users is the government.”
Adversaries not idle
Of particular concern to some was that America’s adversaries have better, more resilient PNT, and are constantly working against us.
They are building PNT “…systems of systems. Space-based, ground-based, and everything in between-based. They are doing it. We need to get out in front and lead,” said one. China has been particularly active building multiple integrated PNT systems.
“Our adversaries are not stupid” and are going to try to stay in the lead. “They will try to interfere with any frequency, system, or combination of systems selected. We must test and build something that is survivable and resilient.”
“If China, Russia, and Iran had the ability to protect themselves from nuclear attack,” said one attendee, “we would be frantically trying to get the same capability. Yet those countries have backup and complementary systems for PNT, and the United States does not. And we’re not doing anything,” said a participant reflecting upon the event.
Hopeful signs
Several attendees said there were signs the event might not have been “just another government meeting.”
As part of his opening remarks, the event host, DOT Deputy Assistant Secretary Dr. Robert Hampshire, mentioned the bipartisan infrastructure law and affirmed that PNT is infrastructure. This led some to believe funding from the infrastructure legislation could be immediately available if the government decided to act.
Others were cheered by DOT Secretary Buttigieg’s cameo appearance and comments at the event. One remarked it was the first time they had heard a DOT Secretary say “PNT” in over 20 years.
Uncertain outcome
Despite the consistent messaging and potentially hopeful signs, some attendees questioned whether anything would change because of the two-and-a-half-hour event.
“There were about 120 people from industry and a wide variety of government agencies, but what was the point?” asked one. “We all told the government the same things we’ve told them before, often in writing.”
Another was concerned that the event didn’t discuss the most important questions.
“We were talking about individual systems and critical infrastructures,” this person said. “This is a strategic national security issue. We need to get the bullseye off GPS and ensure the United States can’t be blackmailed by having GPS held hostage.”
“And what if there is a major coronal mass ejection? China will come out much better than us because they have survivable PNT. The United States will become a second-rate power to China in an instant. We keep talking about the trees and ignoring the forest!”
One attendee whose company has a very active government relations program reported they hoped the event would help sway those in government still opposed to action.
“It is pretty clear to us that almost everyone in the departments who understand the issues is in favor of doing something as soon as possible. The same with Congress. But even though the National Security Council is worried about this, there are some folks in the Office of Management and Budget who have opposed action for over a decade.”
While some came away buoyed by what they saw as an action-oriented tone to the event, others doubted much would change. “It remains to be seen whether criticism from industry and threats from China and Russia are enough to get the government to finally do something.”

Three HawkEye 360 radio-frequency geolocation microsatellites were launched May 25. The satellites, launched aboard SpaceX Transporter-5 mission, were built by Space Flight Laboratory (SFL) of Toronto. Three SFL-built satellites for greenhouse gas monitoring were also launched.
The HawkEye 360 constellation detects and geolocates RF signals for maritime situational awareness, emergency response, national security and spectrum analysis applications.
Once Cluster 5’s on-orbit checkout is complete, the HawkEye 360 constellation will be expanded to 15 satellites, doubling capacity and revisit rates. This significantly boosts the constellation’s ability to serve global customer demand and to monitor activity across places such as Ukraine.
“Every enhanced satellite cluster we launch helps us deliver a higher density of valuable data to our government, commercial and humanitarian customers and partners – advancing our efforts to monitor global activities for a safer and more secure world,” said HawkEye 360 John Serafini. “Launch by launch, these space-based innovations are analyzing the knowns and uncovering the unknowns of the RF spectrum across the globe.”
Cluster 5 includes enhanced antenna functions introduced with Cluster 4, which allow greater flexibility in geolocating signals across a wide range of frequencies important to customers.
Cluster 4, launched April 1, has been completing checkout and moving into final formation to begin collecting data in late June. Cluster 5 is slated to achieve initial operating capability in August.

HawkEye 360 plans to continue to grow the constellation to achieve revisit rates of about 15 minutes to support timely defense, national security and commercial applications.
SFL has now developed 15 microsatellites for HawkEye 360 of Herndon, Virginia. SFL was selected for these missions due to the importance of formation flying by multiple satellites for successful RF geolocation.
Other missions developed by SFL in the past two years include 16 communications CubeSats and three microsatellites designed for Earth observation, maritime tracking and atmospheric monitoring.
In its 24-year history, SFL has developed cubesats, nanosatellites and microsatellites that have achieved more than 191 cumulative years of operation in orbit.
A new platform will detect and characterize GNSS spoofing operations using artificial intelligence and commercially available data
Geospatial intelligence company Orbital Insight has been awarded a contract from the U.S. Department of Defense (DoD) to deliver a technology platform for identifying intentional GNSS interference and manipulation operations across the world.
The platform will leverage commercially available data to detect GNSS spoofing, where falsified or manipulated GNSS signals are used to confuse adversaries or obscure illicit activities, presenting risk to both government and commercial operations. Orbital Insight was selected through DoD’s Defense Innovation Unit (DIU) solicitation process seeking commercial solutions to counter the growing threat of GNSS disruptions to national security.
Research suggests that Russia conducted nearly 10,000 spoofing operations from 2016 to 2018 alone.
The new technology will significantly improve situational awareness for warfighters, intelligence analysts and safety-of-life applications. Orbital Insight’s platform will leverage its multisensor data stack, artificial intelligence and machine-learning capabilities to alert analysts and operators to potential jamming and spoofing events, techniques commonly used by adversarial actors to cover up activities or sabotage operations.
The platform leverages a suite of geolocation data — satellites, AIS, ADS-B and internet-of-things devices — along with new advanced algorithms designed to automatically recognize anomalies linked to spoofing, complemented by research intelligence from the nonprofit partner Center for Advanced Defense Studies. Research suggests that Russia conducted nearly 10,000 spoofing operations from 2016 to 2018 alone.
“Helping organizations understand what’s happening on and to the Earth is at the heart of what Orbital Insight does, and spoofing is a national security problem that has proven challenging to solve,” said Kevin O’Brien, CEO, Orbital Insight. “GNSS spoofing is essentially a data problem, and Orbital Insight’s AI and deep data stack can help identify spoofing, along with other major humanitarian and environmental challenges. This is a perfect example of private and public sectors uniting through technology.”
Other areas that may be addressed: identifying drug trafficking, illegal fishing, sea-borne piracy and unintentional commercial aviation disruptions
The technology has broad implications that extend beyond situational awareness of intentional GNSS interference. Other national security, humanitarian and environmental challenges may be addressed, such as identifying drug trafficking, illegal fishing, sea-borne piracy and unintentional commercial aviation disruptions.
Federal agencies are increasingly complementing their systems with commercial technology and data sources that are unclassified, universally accessible, and shareable with allies. The National Air and Space Intelligence Center will be the first customer to utilize the technology. Upon successful integration, the goal will be to expand this platform widely across the defense, intelligence and civil communities.
Orbital Insight received the DoD contract on the heels of announcing a Phase II Small Business Innovation Research contract from the National Geospatial-Intelligence Agency to deliver a computer-vision model that uses synthetic data to detect novel classes of objects.
The company also recently launched a new class of multiclass object-detection algorithms within its flagship GO platform to help the intelligence community monitor and differentiate activity at thousands of areas of interest. Like all of Orbital Insight’s products, these algorithms are being developed within an ethics framework that shapes the company’s work and values privacy.
The HawkEye 360 constellation detects and geolocates RF signals for maritime situational awareness, emergency response, national security and spectrum analysis applications.

HawkEye 360 Inc. announced the successful launch of its Cluster 3 radio frequency geolocation microsatellites built by Space Flight Laboratory (SFL). Carried aboard the June 30 SpaceX Transporter 2 mission, the Cluster 3 formation-flying microsatellites quickly established communication with the company’s satellite operations center. They join in orbit the HawkEye 360 Cluster 2 and Cluster 1 Pathfinder satellites.
The HawkEye 360 Constellation detects and geolocates RF signals for maritime situational awareness, emergency response, national security and spectrum analysis applications. Cluster 3 significantly expands HawkEye 360’s capacity, and is part of its second generation of advanced RF-sensing satellites.
“With the addition of our second-gen satellites, we’ll offer more frequent, timely and actionable data and insights to our government, commercial and humanitarian partners,” said CEO John Serafini.
“The increased revisit frequency and capacity Cluster 3 brings to our constellation are essential to detecting, characterizing, and understanding the continuously changing RF activity important to our clients,” said Alex Fox, Executive Vice President for Sales and Marketing.
Seven more clusters are fully funded and scheduled for launch in 2021 and 2022 to achieve collection revisits as frequent as every 20 minutes, Fox said. “Each cluster will offer new innovations to address a rapidly growing set of requirements needed by our defense, security and commerce clients. We plan on expanding the constellation past the initial 10 clusters to achieve near-persistent monitoring of global RF activity, which will drive even more value and ensure our continued dominance in the industry.”
HawkEye 360 delivers a layer of intelligence to help understand human activity on Earth. The constellation detects, characterizes and precisely geolocates these RF signals from a broad range of emitters, including VHF marine radios, UHF push-to-talk radios, maritime and land-based radar systems, L-band satellite devices and emergency beacons.
By processing and analyzing these RF data, the company delivers actionable insights for national, tactical and homeland security operations, maritime domain awareness, environmental protection and new applications in the commercial sector, the company said.
The HawkEye 360 launch brings to 20 the total number of SFL satellites placed into orbit in less than a year. The Cluster 3 satellites were built on SFL’s 30-kg Defiant microsatellite bus.
HawkEye 360 selected SFL due to the importance of formation flying by multiple satellites for successful RF geolocation. SFL is the acknowledged leader in developing and implementing high-performance attitude control systems that make it possible for relatively low-cost nanosatellites and microsatellites to fly in stable formations while in orbit.
The previous HawkEye 360 satellite clusters built by SFL were the Pathfinder launched in 2018 and Cluster 2 in January. Each Cluster is comprised of three satellites.
Other launches of SFL-built satellites in the past year include missions developed for the Norwegian Space Agency (NOSA) in Norway, the Dubai-based Mohammed Bin Rashid Space Centre (MBRSC) in the United Arab Emirates, GHGSat Inc. of Canada, Space-SI of Slovenia, and a Canada-based telecommunications company.

“With the addition of L3Harris, the alliance welcomes a company recognized globally for developing and advancing innovative uses of GPS to protect our nation’s national security,” said GPSIA Executive Director J. David Grossman. “Having now tripled membership over the last 13 months, GPSIA is in a position of strength to continue leading advocacy for the promotion, protection and enhancement of GPS, both in the U.S. and around the globe. L3Harris Technologies is an integral part of the deployment of next-generation GPS III satellites and we look forward to working with them to ensure this technology remains the gold standard for delivering positioning, navigation and timing functions to our military as well as a wide range of other sectors, including transportation, agriculture, electricity and finance.”
L3Harris Technologies has played an integral part in the story of GPS, as it has provided navigation technology for every U.S. GPS satellite ever launched. L3Harris Technologies is developing 10 GPS III satellite navigation payloads for the U.S. Air Force’s GPS III satellite program, four of which are already operational.
The company will also provide navigation payloads with fully digital Mission Data Units (MDU) for the U.S. Air Force’s GPS III Follow-On, known as GPS IIIF, satellites. The MDU will provide even more powerful signals and ensure flawless atomic clock operations.
“GPS technology is an important part of the modern world and critical for the warfighter,” said Joseph Rolli, L3Harris Technologies Positioning, Navigation and Timing.
“With more than 40 years of experience developing GPS technologies, L3Harris aims to continue to improve the system with a more powerful, reliable, and flexible signal. We look forward to joining GPSIA and its other industry leading members as we advocate for continued support of this incredible system,” Rolli said.
Advances in geospatial technology have opened up many new possibilities in areas such as national security, urban planning and emergency preparedness. When I was embedded with the U.S. Army as a scientist in Afghanistan, I got to experience firsthand the exceptional value of 3D data. The military used nation-scale imagery and lidar to generate 3D maps that then informed their safety-critical operations. However, since lidar—like most three-dimensional unstructured data—contains incredible complexity and detail, it was painfully slow to analyze manually.
As a result, the impact of this technology was severely restricted by speed and cost due to the significant manual effort required to extract actionable insights. As we looked to the future, where lidar would become commonplace in consumer electronics and automobiles, it became clear that there was an opportunity to combine computer vision/AI with large-scale cloud computing to rapidly and automatically generate actionable insights from 3D data.

After returning from Afghanistan, I reconnected with Krassimir Piperkov, a former colleague from ICON Aircraft, and fellow Stanford alum, to launch Enview. Our objective was to automate 3D geospatial analytics and create a living 3D model of the world to help organizations to protect their critical infrastructure and communities.
Powering geospatial data with AI can take the limits off 3D data analytics, prevent threats from becoming incidents, and protect critical infrastructure. What used to take days or months to process can now be done in minutes, enabling analysts, operators, and decision-makers across the public sector to make timely and accurate decisions. By enhancing our understanding of the physical world, this technology empowers us to tackle pressing challenges like wildfire prevention, humanitarian assistance, disaster response, and more.
Let’s take a look at how AI-powered 3D modeling is being put to use.
Digital twins
A living 3D model of the world, or a digital twin, can be used for many purposes. Enview’s software fuses many different data sets together to create digital twins that are global in scale but have high-resolution to enable local decision-making. These digital twins include 3D terrain, vegetation, buildings, and infrastructure such as power lines, roads, and water works. Enview also fuses real-time and forecasted conditions, such as wind, temperature, humidity, traffic, and IoT (internet of things).
This sort of rich representation of the physical world is an incredibly complex big data challenge. Data comes from radically different sensor modalities, with different resolutions, formats, time-domains, and accuracy. AI plays a critical role in automating the fusion of these datasets, by helping to intelligently align and then fuse them into a cohesive entity. 3D geospatial data is particularly challenging, as it is unstructured data, which requires a new generation of deep learning frameworks whose convolutional kernels are specifically developed from the ground up to work on unstructured data. Further, the datasets are massive in scale. A square-mile of 3D lidar data can have hundreds of millions of points; the magnitude of the data easily passes the petabyte scale when one considers applications that span nation-scale areas. In order to process this volume of data, modern geospatial AI architectures must be containerized and dynamically deployable across cloud compute resources to generate timely insights.
AI is essential to help human experts to extract meaningful insight from this overabundance of data. The application of automated workflows allows experts to look at larger areas, with more speed and higher frequencies. This machine-assisted cognition draws upon the respective strengths of people and computers to do what neither could do on their own.
Humanitarian aid and disaster relief
3D models can be built to monitor hurricane hotspots, such as the Gulf Coast, before major storms strike. By layering in real-time weather information such as rainfall, winds, and flooding, these models can help with planning, emergency response, and relief efforts.
This data also provides life-saving insight that can assess damage to buildings, transportation, and downed power lines, in addition to determining where to send medical and relief supplies, and how to best get them there. 3D data can help to lessen the impact of future weather events by updating the baseline understanding of how storms impact coastal communities so they can plan for the future.

Infrastructure protection
Inadequate clearances between vegetation and power lines can result in wildfires and unplanned power outages. Many federal, state, and local regulations are in place to mandate clearances, and power line operators monitor their networks continuously to ensure that they abide by these regulations and prevent incidents and outages. However, doing so by walking or flying the lines and judging distances with the human eye is challenging and inaccurate.
The ability to identify the exact location and clearances of high-risk vegetation early, and at scale, lets operators identify, prioritize, and address problem areas proactively. Lidar-driven programs have helped with risk-reduction, but are constrained by the massive levels of manual data manipulation required to derive insights from this 3D data. The automation of 3D geospatial analytics through AI, machine vision, and parallel computing enables the accurate and rapid identification of at-risk areas, protecting critical infrastructure and communities.

Fighting wildfires
Devastating wildfires resulting in the loss of life and property have become commonplace in the western U.S. and other parts of the world. The tools and methods previously relied on to keep communities and infrastructure safe are now struggling to keep up with this increased threat.
Geospatial information, including 3D data, provides a digital view of the physical world and, when paired with AI, gives stakeholders the informational edge they need to minimize wildfire damage, injuries, and deaths. This technology can be used to automatically build and update real-time, high-resolution wildfire risk maps that give firefighters and communities more notice when threats are imminent, and provide firefighters with real-time situational awareness when they’re fighting the blazes.
Change detection
According to the Pipeline and Hazardous Materials Safety Administration (PHSMA), third-party excavations are one of the leading causes of pipeline incidents in the U.S. These incidents can lead to service disruptions, expensive repairs, and sometimes serious injuries or deaths.
Detecting signs of excavation or earth movement via aerial patrolling is challenging and costly, while resource limitations make it difficult for pipeline operators to continuously monitor remote areas such as farms. AI-powered 3D maps can be used to monitor topography and accurately detect changes that threaten pipelines in real time.
3D data provides remarkable value when it comes to decision-making as it relates to many different applications—from military defense to protecting neighborhoods from wildfires. However, its success hinges on one thing: speed. The ability to process 3D geospatial data rapidly, and at scale, is made possible through advances in AI and cloud computing. In the future, we can expect to see more exciting and innovative use cases for AI-powered geospatial technology.
