constellr Thermal Satellite Intelligence (SkyBee)

constellr is a thermal intelligence company headquartered in Munich, Germany, with offices in Freiburg, Berlin, Brussels, Toulouse and Washington, D.C. It measures surface temperature from space to show activity and stress that optical images miss, such as crop water stress weeks before fields turn brown, urban heat islands or whether industrial equipment is running.

Its SkyBee satellites carry thermal infrared sensors with 30 m native resolution sharpened to 10 m, absolute accuracy of 1.0-1.5 K, day and night imaging and a 1.5-day average revisit. Two satellites have delivered operational data since 2025, supported by its own mission operations, processing pipeline and data platform. Solutions cover food and water security, urban dynamics, industrial monitoring, maritime awareness and national security for ministries, water authorities, cities, insurers and asset operators.

• Food and water security: field-level thermal signatures linked to soil moisture and crop stress.
• Urban dynamics: night-time hotspots and day-night temperature patterns for cooling plans.
• Industrial monitoring: localised heat on rooftops and machinery for predictive maintenance.
• Maritime awareness: thermal wakes and engine status to track vessels without AIS.
• Infrastructure status: verifies whether power plants and critical sites are operating.
• End-to-end system: own satellites, mission control, processing pipeline and data platform.

• Irrigation companies and large farms in the Mekong Delta or Central Highlands scheduling water based on thermal stress maps.
• City planners in Hanoi or Ho Chi Minh City locating heat islands for green and cooling investments.
• Industrial park operators checking equipment heat anomalies across many sites.

• Detects crop water stress weeks before it is visible in optical imagery, so irrigation can be targeted.
• Calibrated absolute surface temperature with 1.0-1.5 K accuracy and sensitivity below 0.1 K.
• Day and night thermal coverage with 1.5-day average revisit.
• Field-level 10 m sharpened thermal maps for farms, cities and industrial sites.

Droughts, saline intrusion and heatwaves are making water efficiency a priority for agriculture and cities. In Southeast Asia, including the Mekong Delta, irrigation authorities and agribusinesses need frequent field-level water stress data, while fast-growing cities face rising urban heat.
