Who are the major Earth observation companies?

The major commercial Earth observation companies are Planet (optical), Maxar Technologies (optical, very-high-resolution), Capella Space (synthetic-aperture radar), BlackSky (rapid-revisit optical), Satellogic, ICEYE (SAR), and several emerging operators of hyperspectral and thermal-infrared sensors. Government operators (USGS Landsat, ESA Copernicus) sit alongside as the largest data providers by volume.

Earth observation (EO) means looking down from space. The companies in the category split by sensor type: optical (visible/near-infrared imagery), synthetic-aperture radar (SAR, works through clouds and at night), hyperspectral (chemistry from spectral signature), thermal infrared (heat), and radio-frequency monitoring.

The optical incumbents and challengers

Planet: runs the world’s largest constellation of optical satellites; daily revisit of the entire landmass via “Dove” CubeSats, plus higher-resolution SkySats
Maxar Technologies: the historic very-high-resolution provider (WorldView, GeoEye lineage); ~30 cm imagery used in defence and mapping
BlackSky: sub-metre constellation optimised for rapid revisit
Satellogic: sub-metre with a daily-revisit roadmap, headquartered in Uruguay/Argentina
Albedo: pursuing very-low-altitude high-resolution from drag-managed satellites

SAR: synthetic-aperture radar

Capella Space: sub-50 cm SAR; the highest-resolution commercial SAR in market
ICEYE: Finland-based; large constellation, persistent monitoring use cases
Umbra: high-resolution SAR with a defence focus
Synspective: Japan-based SAR operator

Hyperspectral and emerging modalities

Pixxel: broad-spectrum hyperspectral operator, India-based
Wyvern: hyperspectral, Canada-based
HyperSat / Orbital Sidekick: hyperspectral with industrial monitoring focus
Muon Space: multi-modality including weather and GHG sensing
Tomorrow.io: radar-based precipitation observation

RF and signals monitoring

HawkEye 360: RF emissions mapping for maritime and security
Kleos Space: RF, later phases of the constellation
Unseenlabs: RF, France-based, maritime focus

Government counterparts

Commercial operators sit alongside, not in place of, government EO programs:

USGS Landsat (since 1972): the longest-running multispectral record
ESA Copernicus / Sentinel: open-access global imagery
NASA Earth Science: climate-focused missions (PACE, SWOT, NISAR co-developed with ISRO)
NOAA / EUMETSAT: weather satellites including GOES and Meteosat

Where the value flows

A few patterns shape the industry:

Government customers (NRO, NGA, defence ministries) dominate revenue
Pure commercial demand is concentrated in agriculture, insurance, and energy
AI / analytics layers are increasingly bundled with imagery (the question isn’t “do you sell pixels” but “do you sell answers”)
