A recent report from NASA’s Commercial Satellite Data Acquisition (CSDA) program has confirmed the suitability of data from Satellogic’s NewSat constellation for scientific applications. Released on March 9, 2026, the Radiometric & Geometric Quality Assessment Report details the evaluation conducted by NASA subject matter experts (SMEs) on the quality of the constellation’s data products.
Evaluation Process and Findings
The assessment involved analyzing 60 top-of-atmosphere reflectance images collected between 2021 and 2025. The focus was on both radiometric and geometric performance across various sites. The results indicated a generally strong radiometric accuracy, with most spectral bands performing within 10% of the reference values from Aqua MODIS. Furthermore, the signal-to-noise ratios met the “Good” rating criteria for over half of the bands analyzed.
Geometric Performance Insights
In terms of geometric performance, the data exceeded the specified sensor spatial response specifications. Notably, the Mark IV sensors received an “Excellent” grade for their spatial response, while the Mark V sensors were rated as “Basic”. This variability highlights differences in performance between the two sensor generations.
Response and Future Assessments
Following the report’s release, Satellogic has initiated changes to their data processing methods to address the findings and recommendations outlined by the SMEs. The CSDA program is currently engaged in a quality assessment of these revised products, with results expected to be reported in the near future.
About the CSDA Program
The CSDA program, established by NASA’s Earth Science Division (ESD), aims to identify, evaluate, and acquire commercial remote sensing data that enhances NASA’s Earth science research. By providing structured opportunities for emerging commercial satellite data vendors, the program facilitates the integration of innovative data sources into NASA’s scientific endeavors. The CSDA’s streamlined evaluation process, led by SMEs, ensures timely access to high-quality, mission-relevant commercial data, ultimately fostering innovation and improving data products.
