Indian space startup SatLeo Labs has placed its first thermal-imaging payload, TAPAS-1, in orbit, marking an important step in the company’s plan to build a dedicated space-based thermal intelligence capability from India.
TAPAS-1 was launched aboard Dhruva Space’s LEAP-2 satellite platform on SpaceX’s Transporter-18 rideshare mission from Vandenberg Space Force Base in California on October 1, 2026. SatLeo Labs subsequently confirmed the payload’s successful orbital deployment.
The company describes TAPAS-1 as India’s first privately developed commercial thermal-imaging payload.
TAPAS-1 Built and Tested in Ahmedabad
SatLeo Labs designed, manufactured and tested TAPAS-1 at the IN-SPACe facility in Ahmedabad.
The mission moves the company from ground-based development into orbital validation. Rather than building an independent satellite bus for its first flight, SatLeo hosted the payload on Dhruva Space’s LEAP-2 mission.
Dhruva Space provided the P-30 satellite platform, launch integration and supporting ground infrastructure, allowing SatLeo to focus on its thermal-imaging technology.
Thermal Imaging Adds a Different Layer of Earth Observation
Conventional optical satellites primarily record reflected sunlight. Thermal sensors measure infrared radiation associated with surface temperature, revealing patterns that visible-light imagery may not capture.
SatLeo is developing sensors across mid-wave infrared, long-wave infrared and visible wavelengths. The company says its architecture is designed to identify temperature differences with accuracy of around one Kelvin.
This makes thermal observation useful for detecting heat variations across agricultural land, cities, industrial assets and natural environments.
Agriculture and Water Stress Are Key Applications
Agriculture is one of the primary uses identified by SatLeo Labs.
Crops experiencing water stress can develop temperature changes before visible symptoms appear. Thermal data can therefore help identify irrigation problems, moisture stress and areas requiring closer monitoring.
Repeated observations can also support more efficient water use by showing how temperature patterns evolve across farmland.
Urban Heat and Infrastructure Monitoring Expand the Use Case
Thermal imagery can map temperature differences across roads, buildings, vegetation and water, helping identify persistent urban heat islands.
SatLeo is also targeting infrastructure and industrial monitoring, where abnormal temperature patterns can provide information about equipment, power systems, solar installations and other assets.
The same capability can support environmental monitoring and disaster-response applications, including wildfire detection and broader climate analysis.
AI and Edge Computing Support Faster Analysis
SatLeo’s longer-term architecture combines thermal sensing with artificial intelligence and onboard edge computing.
Selected processing can be performed aboard the spacecraft before transmission to Earth, reducing the amount of raw data that needs to be downlinked.
Machine-learning models can then be used to identify patterns, anomalies and temperature changes relevant to specific applications.
The objective is to deliver processed thermal intelligence rather than only raw infrared imagery.
TAPAS-1 Supports a Larger Constellation Plan
SatLeo Labs plans to build a low-Earth-orbit constellation of thermal-imaging microsatellites.
A constellation would allow the company to revisit locations more frequently and build time-series datasets showing how temperature patterns change over time.
That repeat coverage is particularly valuable for agriculture, urban heat monitoring, disaster response and industrial applications.
TAPAS-1 is the first orbital step towards validating the sensor, processing architecture and operational model required for that larger network.
India’s Private Space Ecosystem Gains a New Capability
The TAPAS-1 mission also demonstrates how India’s private space companies are beginning to specialise and work through shared infrastructure.
SatLeo developed the thermal payload, Dhruva Space supplied the satellite platform and launch integration, while IN-SPACe facilities supported development and testing.
This model allows startups to focus on specialised technologies without independently building every element required for an orbital mission.
With TAPAS-1 now in orbit, SatLeo Labs has moved its thermal-imaging programme into the operational space environment. The mission establishes a foundation for a future Indian commercial constellation focused on thermal Earth observation and expands the range of capabilities emerging from the country’s private space sector.
