British investment firm Seraphim Space surveyed the Earth statement sector a couple of years ago, categorizing startups by sensor type.
Analysts determined that firms focused on electro-optical and artificial aperture radar were advancing rapidly. Thermal imagery startups weren’t.
“Much to our surprise, it was the one sensor area that didn’t have any corporations that had really progressed,” said Seraphim Space CEO Mark Boggett. “None of the businesses had raised $10 million, let alone $100 million or $500 million like among the other sensor areas.”
All that’s changing. Startups focused on gathering thermal imagery via satellite are attracting investment, making acquisitions and winning contracts.
“It’s the subsequent big thing in Earth statement,” said Anthony Baker, founder and CEO of Satellite Vu, a British Earth-observation startup. “Nobody has opened up the frontier on infrared.”
The brand new businesses focused on thermal imagery vary widely. What the founders share is the conviction that startups can provide the variety of data only expensive government satellites supplied up to now.
Urgent Climate Motion
Climate change is propelling much of the work. Enterprise capital firms are flocking to startups promising to trace emissions or mitigate the impact of droughts, floods and forest fires.
“There’s an urgency to do something,” said Max Gulde, CEO and co-founder of German startup constellr. “Having a thermal picture of our planet at an actionable resolution and frequency is something which is missing in our understanding of climate change. Suddenly, there’s a push for that.”
Thermal imagery startups are also benefiting from recent declines in launch costs and technological advances.
“After I began founding the corporate, everyone was explaining to me
that the sensor we wanted to construct was inconceivable,” said Thomas Grübler, CEO and co-founder of Munich-based OroraTech. “Now, it’s possible to shrink these big complex systems to smallsat and cubesat scale.”
What’s more, founders have identified government and industrial customers willing to pay for thermal imagery. Farmers are buying data that help them irrigate crops without wasting water. And fire departments are looking forward to access to satellite images that reduce the necessity for dangerous aerial flights over wildfires.
“It’s getting cheaper to construct a specialist constellation that may perform certain tasks extremely well,” Gulde said. “Suddenly, you’re passing a threshold where individuals are willing to pay.”
The European Commission and the European Space Agency awarded contracts in June to constellr, OroraTech and Spanish startup Aistech Space.
The businesses will supply thermal data to enhance observations collected through the European Union Copernicus Earth-observation program.
Data Fusion
When Albedo, a Colorado startup, was founded in 2020, the marketing strategy focused on collecting 10-centimeter-resolution optical imagery from telescopes in very low Earth orbit. The founders soon realized they may obtain longwave infrared imagery from the identical satellites without much additional cost.
“With the optical resolution, we are able to go from counting cars to identifying cars,” said Albedo founder and CEO Topher Haddad. “With thermal, you may see where a automotive probably just pulled out from a parking spot.”
Plus, the mixture of optical and thermal imagery helps observers distinguish hot tubs from pools or trampolines, and backyard dwelling units from sheds.
Albedo has raised $58 million for refrigerator-size satellites scheduled to start launching in 2025.
Work on Albedo’s infrared technology is being funded by the U.S. Air Force National Air and Space Intelligence Center under a $1.25 million contract. Under one other $1.25 million contract, the Air Force is working with Albedo to look for tactics to integrate Albedo imagery tasking with government systems.

Ecosphere Health
Constellr is preparing to launch satellites in 2024 to assemble thermal data for agricultural and environmental-monitoring applications.
For the reason that company was founded in 2020, constellr has raised about $14 million in enterprise capital and received a further $14 million in grants.
Earlier this 12 months, constellr acquired ScanWorld, a Belgian hyperspectral satellite imagery and analytics startup. With 4 shoebox-size satellites equipped with infrared sensors, constellr plans to assemble each day imagery of agricultural fields all over the world. By adding hyperspectral data, constellr may also help farmers discover crop disease and manage fertilization schedules.
Under the five-year, $5 million Copernicus contract announced in June, constellr will provide thermal imagery to hundreds of European institutions.
“We’ve been working with the European Space Agency for quite a while,” Gulde said. “Government support has been exceptional.”

Water Scarcity
Washington-based Hydrosat has raised $35.6 million to acquire thermal data from space. Supporting sustainable agriculture and helping customers reduce carbon emissions are the corporate’s primary goals.
Thermal data can pick up initial signs of drought two to 4 weeks before optical imagery shows a change in the colour of vegetation, said Pieter Fossel, Hydrosat CEO and co-founder.
In June, Hydrosat acquired IrriWatch, a Netherlands company that delivers each day climate, crop, soil and irrigation updates to farmers.
“With IrriWatch, we are able to point to examples of how customers using
this product, based on thermal satellite insights, are capable of reduce water use,” Fossel said. “In plenty of parts of the world, reducing water use means less electricity for pumping that water out of the bottom, less electricity for operating that mechanized center pivot irrigation system. And if the irrigation system is being run on diesel fuel, that’s a direct, measurable carbon reduction for the farm along with improvements in production, the boosting of yields and the reduction of water.”
Hydrosat, founded in 2017, plans to launch its first two satellites next 12 months to “deliver thermal infrared data in addition to multispectral infrared data with higher resolution and greater revisit than what is out there today,” Fossel said. “As a climate-oriented business, having the ability to have very tangible, measurable impacts is something that’s really vital to us.”

Fire Danger
After being told thermal imagery couldn’t possibly be captured with cubesats, OroraTech’s founders raised $22.4 million to prove naysayers flawed. The German startup demonstrated its first uncooled thermal
infrared sensor on a Spire Global cubesat in 2022.
“People told me I wouldn’t see anything with this camera,” Grübler said. “We see fires at comparable quality to the Visible Infrared Imaging Sensor. We also see temperature quite well.”
OroraTech plans to gather global imagery every half-hour with a constellation of 96 satellites. The primary eight satellites, built and operated by Spire Global under an agreement announced June 28, are slated to launch right into a late-afternoon sun-synchronous orbit in 2024.
“We would like to grasp the trends in temperature, whether it’s for urban heat, industrial activity or forest fires,” Grübler said. “We would like to be the primary one to not only know where the forest fire is however the intensity of the forest fire and the way it can behave.”

Data Sharing
SatVu was founded in 2016 to assemble high-resolution thermal imagery with 160-kilogram satellites. After raising 12.7 British kilos ($16 million) for satellites designed and manufactured with Surrey Satellite Technologies Ltd., SatVu launched its first spacecraft in June.
A second satellite is slated to launch in 2024. SatVu’s eight-satellite constellation needs to be operating in a few years, Baker said.
To this point, 66 corporations have committed 128 million kilos to SatVu’s Early Access Programme. SatVu customers who enroll for the Early Access Programme can task SatVu’s airborne sensor to gather thermal imagery and procure discounts on future satellite-tasking orders.
Defense and intelligence agencies could also be SatVu’s first customers “because they already know what the information looks like,” Baker said. “They only don’t have a industrial data source they’ll share with allies.”
One other potential application is industrial activity monitoring.
“With infrared, you may see activity in a constructing,” Baker said. “If it’s dormant, it probably has no heat signature. If it’s an lively factory, you may see which parts of the factory are operating.”

Foldable Telescopes
Earlier this 12 months, Spain’s Satlantis acquired a majority stake in SuperSharp, a British university spin-out developing unfolding space telescopes to acquire thermal infrared imagery.
UK government agencies have provided initial funding for SuperSharp.
The subsequent milestone is to get to a space-rated version of our telescope, which we plan to do by the tip of this 12 months,” said Marco Gomez-Jenkins, SuperSharp co-founder and CEO. “After that, we’re specializing in testing our telescope in space by early 2025.”
Satlantis, meanwhile, sells a wide range of Earth statement payloads and manufactures satellites like Armenia’s Armsat-1, launched in 2022.
Once SuperSharp’s infrared telescope is flight-proven, the corporate will begin selling foldable telescopes for microwave-size cubesats and developing a bigger version of the telescope for higher-resolution imagery.
Guardian Satellites
Certainly one of the primary startups to launch a thermal infrared imaging satellite was Aistech. The Spanish startup’s first cubesat equipped with a multi-spectral telescope to gather visible, near-infrared and thermal infrared
imagery reached orbit in 2022.
“Temperature is a novel data source that is vital to understanding activity on the Earth’s surface and the changes that may occur,” Aistech founder Carles Franquesa told by email. “And for this, Aistech’s strategic plan involves deploying its space infrastructure to observe these changes constantly and accurately.”
Aistech is preparing to launch 20 Guardian thermal-imagery satellites right into a constellation, scheduled to be accomplished in 2027, with applications including water management, forestry, environmental monitoring and maritime security. Two additional Guardians are set to launch within the second quarter of 2024.
In June, Aistech was named a Copernicus Contribution Mission contract.
“Becoming a part of the select group of corporations that provide data generated by their very own constellation of satellites through the Copernicus Contributing Missions programme marks a vital milestone for the corporate, since a reference client akin to ESA validates that each the technology developed and the information generated by Aistech satellites will provide a brand new vision of the changes that occur on the Earth’s surface and a price to society facing latest challenges on the planet,” Franquesa said. “ESA, through this program, is carrying out vital work in promoting and developing latest applications based on geospatial intelligence, which can allow a brand new generation of corporations to supply latest solutions to specific problems; and this entails an exponential growth in the necessity for brand new satellite data, and due to this fact an important development of the space thermal imaging market in the approaching years.”
