SatVu's HotSat 2 satellite delivers thermal detail roughly 30 times sharper than the U.S. Landsat satellites, whose thermal band tops out near 100 meters, turning per facility activity monitoring into a commercial product for energy, data center, and defense buyers.
For decades, only government satellites could read the heat signature of a specific industrial site from orbit: a working refinery, a busy data center, a runway under operation. A UK-led startup called SatVu has now moved that capability into a commercial product line, with thermal-imaging data sharp enough to distinguish one industrial facility from the next.
The company's second satellite, HotSat-2, was launched aboard a SpaceX Falcon 9 from Vandenberg Space Force Base and delivers mid-wave infrared data at 3.5-meter pixel resolution, both day and night. That is roughly 30 times sharper than Landsat, the long-running civilian Earth-observation workhorse, whose thermal band tops out near 100 meters and shows regional patterns rather than per-site activity. With 3.5-meter pixels, a buyer can read whether a specific data center is drawing power, whether a refinery unit is in operation, or whether a military site shows unusual thermal signatures, instead of estimating that from a regional average.
Thermal imaging is not a replacement for the existing commercial Earth-observation stack. Optical satellites still show what is on the ground, and synthetic-aperture radar (SAR) still maps structures and surface change through cloud and at night. Thermal adds a fourth layer that captures a different signal entirely: heat. As SatVu's new CTO Scott Herman, who previously held senior geospatial-intelligence roles at Maxar Technologies and BlackSky, put it in the EE Times feature: "Thermal [data] provides a level of activity insight that hasn't been available before."
The institutional backing is real. In late 2025 and early 2026, SatVu closed a funding round reported at $40 million, anchored by the NATO Innovation Fund, which the company and SpaceNews framed as a signal that military and intelligence buyers now see orbital thermal as operationally relevant. SatVu has also been selected as one of five industry partners on the U.S. National Geospatial-Intelligence Agency's Luno A and Luno B programs, and announced a U.S. distribution partnership described as "America's mapping leader" for bringing thermal intelligence to U.S. customers.
CEO Anthony Baker posted an open letter shortly before Christmas 2025 titled "We will give everyone access to thermal intelligence in 2026," and the company has begun showing what that looks like in practice. First-light imagery from HotSat-2, later summarized by Electronics Weekly, tracks live activity at three strategic energy sites in Australia, India, and Cuba. A third satellite, HotSat-3, is described by SatVu and Satellite Today as planned for launch later in 2026, with no firm date disclosed.
The honest caveats belong in the story. HotSat-1, SatVu's first satellite, suffered what the company has called a "fatal camera anomaly" after roughly six months in orbit, ending the mission well short of a typical multi-year commercial lifespan. Resolution, revisit rate, and dependence on clear skies still bound what orbital thermal can actually deliver for any given site. And the framing of this as a "fourth wave" of Earth observation is, for now, company and trade-press language rather than an independent market category.
What to watch next is straightforward. HotSat-3's launch will test whether a third platform can extend HotSat-2's revisit cadence and whether the company can keep its cameras alive longer than its first satellite did. Whether NATO Innovation Fund money translates into recurring defense and intelligence contracts, and whether the U.S. partnership produces named customers beyond press-release language, will determine whether activity-level thermal intelligence stays a SatVu pitch or becomes a standard line item in commercial geospatial procurement.
