Satellite imagery is entering a new phase. The next breakthrough is not simply higher resolution. It is reliable access: through clouds, at night, and at a scale large enough to support everyday decisions.
That is the goal of Extellis, a Durham-based startup founded from research at Duke University. The company is developing satellite technology that could capture up to 10,000 images per day, compared with the few hundred produced by many existing systems.
For homeowners, contractors, cities, farmers, energy companies, and disaster-response teams, that difference could change how the physical world is measured and monitored.
Extellis’ Satellite Technology Edge
Extellis grew out of more than a decade of research in Duke engineering professor David Smith’s lab. CEO and co-founder Michael Boyarsky began working on the technology as a Duke graduate student before helping turn the research into a commercial company.
The company’s core innovation is a patented metasurface antenna designed for synthetic aperture radar, or SAR.
Unlike traditional optical satellite cameras, SAR does not depend on sunlight or clear skies. It uses radio waves to create images that can work:
- Through cloud cover
- At night
- In smoke and some atmospheric obscurants
- Across large geographic areas
- On a repeated, high-frequency schedule
Extellis describes its antenna as a lightweight, planar system capable of rapid horizon-to-horizon beam steering. In practical terms, the satellite can redirect its imaging capability without relying on large mechanical structures or conventional reflector dishes.
That design is intended to address several long-standing SAR limitations:
- High power consumption
- Thermal management challenges
- Expensive hardware
- Limited collection capacity
- Slow repositioning between targets
The result is a satellite built for volume, not just occasional observation.
From Defense Technology to Everyday Infrastructure
Boyarsky has compared the satellite’s radar process to the technology used in airport body scanners.
The comparison is useful because both systems send signals toward an object and interpret the returned data to identify what is present. The satellite does not need a visible-light photograph to understand the surface below.
Boyarsky’s broader goal is to make satellite imaging useful beyond defense. The technology is intended to support:
- Farming: Monitoring fields, crops, soil conditions, and irrigation
- Energy: Tracking pipelines, facilities, and infrastructure corridors
- Disaster response: Assessing damage when clouds, smoke, or darkness block optical imagery
- Transportation: Monitoring roads, ports, railways, and logistics networks
- Environmental management: Detecting subsidence, vegetation changes, and land movement
That commercial focus helps explain the interest from investors. Extellis raised a $6.8 million seed round, supported in part by Duke Capital Partners, along with earlier non-dilutive funding for antenna development. In July 2026, Shell Ventures joined the company’s funding round.
Shell’s participation is especially relevant. Energy and infrastructure operators need consistent data across large areas, but traditional inspections can require helicopters, ground crews, or long gaps between visits.
Extellis’ pathfinder mission is expected to move the technology toward orbit, with a launch possible as early as the end of 2027.
“While today’s satellites only cover a tiny fraction of Earth, ours will reliably monitor Earth at an industrial scale,” Boyarsky said in a Duke report on the company.
Why 10,000 Images Per Day Matters
Many satellite systems produce valuable imagery but operate under strict limits. A satellite may have to prioritize certain customers, wait for daylight, avoid cloud cover, or spend time repositioning before it can collect the next image.
Extellis is targeting a different operating model.
Its stated objective is up to 10,000 images per day. That capacity could support more frequent monitoring and make satellite information more affordable for commercial users.
The potential benefits include:
- Faster updates after hurricanes, tornadoes, floods, and wildfires
- More frequent monitoring of long energy corridors
- Better visibility into agricultural conditions
- Reduced dependence on manual inspections
- More useful data for insurance and infrastructure planning
- Improved ability to compare changes over time
The important point is not just the number of images. It is the combination of high capacity, all-weather access, and day-night operation.
Raleigh Is Already Building a Data-Driven City
Extellis is part of a larger technology story developing across the Research Triangle.
Raleigh is using artificial intelligence, cloud computing, and geospatial mapping to improve traffic management. The city’s pilot combines:
- NVIDIA Metropolis and DeepStream for real-time video analytics
- Esri ArcGIS for geospatial visualization
- Microsoft Azure for cloud infrastructure
- A digital twin that represents traffic activity across the city
The system analyzes camera feeds to detect vehicles, track trajectories, and evaluate turning movements at intersections. According to NVIDIA’s Raleigh case study, the pilot achieved approximately 95% vehicle detection and trajectory accuracy.
Microsoft reports that Raleigh moved video feeds from 12 traffic cameras into Azure and created the first pilot digital twin in roughly six weeks.
The financial impact could be significant. Raleigh estimates that improving traffic flow by reducing delays by 4.5 seconds at 10 signals along a major corridor could save commuters approximately $9.7 million annually in time and fuel costs.
The digital twin also gives city planners a way to test possible changes before making them in the real world. They can analyze traffic flow, identify bottlenecks, evaluate safety concerns, and plan for special events using a living model of the city.
That is the same basic principle behind the next generation of satellite applications: measure the physical world remotely, process the data quickly, and turn it into a practical decision.
What This Means for Roof Measurement
Roofing is one of the clearest examples of how satellite and aerial imagery can simplify a traditionally slow process.
A conventional roof estimate may begin with several contractor visits. Each contractor must schedule time, travel to the home, inspect the roof, measure the structure, and prepare a price. Homeowners can wait days just to learn whether their project may cost $10,000, $15,000, or more.
Satellite-powered measurement changes that first step.
At Get My Roof Estimate Now, homeowners enter an address and receive a free estimate in about 60 seconds. The platform analyzes roof size, pitch, and complexity to provide low, middle, and high replacement price ranges.
A typical 2026 roof replacement is often within the following broad ranges:
- Architectural shingles (Popular): Approximately $9,000–$13,000 for a 2,000-square-foot roof
- Metal roofing (Premium): Approximately $20,000–$28,000
- Synthetic roofing (Premium): Approximately $16,000–$32,000
- Roof coatings (Budget): Approximately $6,000–$7,500 where appropriate
These are planning figures. Actual costs vary based on roof geometry, labor, materials, tear-off requirements, permits, and regional pricing. Homeowners can also use the roof cost calculator to compare materials and regional conditions.
Current satellite and aerial roof measurement systems typically work best when they can access a clear, unobstructed view. Clouds are primarily a data-availability problem for optical imagery.
Roughly 70% of Earth is covered by clouds at any given time, although cloud cover varies by region and season. Most roof-measurement workflows address this by using:
- Archived imagery from multiple dates
- Cloud filtering and masking
- More than one imagery source
- Computer vision that identifies roof planes and features
- Human or contractor verification when conditions are difficult
Extellis’ future all-weather radar capability could eventually strengthen this process. If radar imagery can provide reliable roof information through cloud cover and at night, measurement platforms may have more opportunities to analyze properties that are difficult to capture with optical imagery alone.
That does not mean SAR will replace every current measurement method. Roof condition, decking damage, flashing problems, leaks, and ventilation issues still require professional inspection. But better imagery could improve the speed, availability, and consistency of the initial measurement.
The Future Is Faster, Not More Complicated
The most useful technology is often the technology that removes friction.
Raleigh’s traffic pilot does not ask residents to understand the entire AI and cloud architecture behind the system. It uses that architecture to improve traffic timing and safety.
Likewise, homeowners do not need to understand satellite imaging, computer vision, or roof segmentation to benefit from a faster estimate. They need a reliable starting point for budgeting and planning.
Extellis is working to make satellite imagery:
- More dependable
- More frequent
- More affordable
- More useful for commercial and public applications
That same direction is already visible in roofing. Homeowners can measure a property remotely, compare materials, understand regional costs, and connect with verified local contractors before scheduling an inspection.
The technology is still developing, and Extellis’ first satellite has not yet launched. But the trajectory is clear: better data is moving closer to the moment when people need to make decisions.
What Homeowners Should Do Now
You do not need to wait for the next generation of satellites to start planning a roof replacement.
If your roof is 15–30 years old, has storm damage, or may affect a future home sale:
- Check the roof’s age and visible condition.
- Get an address-specific estimate instead of relying only on national averages.
- Compare architectural shingles, metal, synthetic materials, and coatings.
- Review low, middle, and high price ranges.
- Use the estimate as a benchmark when speaking with contractors.
- Confirm licensing, insurance, warranties, and the written scope of work.
Start with a free satellite-powered roof estimate. It takes about 60 seconds, requires no credit card, and gives you useful pricing information before a contractor visit.
