Private-Sector Small Constellation Satellite Data Product Pilot Evaluation
About the Pilot
In December 2017, NASA's Earth Science Division (ESD) launched the Private-Sector Small Constellation Satellite Data Product Pilot (referred to hereafter as the Commercial Smallsat Data Acquisition Program [CSDAP] Pilot) with the objective of identifying, evaluating, and acquiring remote sensing imagery and data that supports NASA’s Earth science research and application activities.
Under the Pilot program, NASA awarded contracts to three companies—Planet; Maxar (formerly DigitalGlobe Inc.); and Spire Global, Inc.—that met the criteria within the public request for information (RFI). The small satellites were required to:
- have satellite constellations comprised of three or more satellites from U.S. companies operating and collecting data in a non-geostationary orbit (not following the Earth's rotation);
- provide consistent, global coverage; and
- be designed and operated by non-governmental entities.
To evaluate the data, ESD identified 41 existing NASA-funded research projects that could potentially benefit from and had expertise to evaluate the imagery and/or data being considered for purchase. The pilot evaluation program took place from January 1, 2019 to December 16, 2019.
Principal investigators (PIs) from all six ESD Research and Analysis (R&A) thematic areas, the four Applied Science program elements, and the Heliophysics Space Weather program participated in the evaluation.
These NASA-funded researchers were selected to examine and analyze the data to help determine their utility for advancing NASA’s science and applications development goals. In addition to the assessments of the scientific suitability, other evaluation criteria included data availability (latency), license rights versus cost, and the vendor’s plans for constellation maintenance and evolution. In addition, CSDAP funded three researchers with expertise in calibration and validation of multi-spectral imagery assessed the radiometric calibration and geolocation accuracy of Planet and DigitalGlobe multispectral imagery.
As a requirement of the Program, the participating PIs were asked to submit two progress reports and a final evaluation on the usefulness of commercial data to meet the research and application needs. Findings from the PI reports indicated that the pilot program data is of sufficient quality for continued access and the pilot program has now transitioned to CSDAP.
Pilot Program Activities
The NASA Earth Science Division presented a Town Hall at AGU (PDF), Tuesday, December 10, 2019 and a Side Panel Discussion at AMS (PDF), Monday, January 13, 2020 to provide a status update on the pilot activity, answer questions about data access and on-ramps for other constellation owners, and answer questions from the community.
The Commercial Smallsat Data Acquisition Program (CSDAP) hosted a brown bag session to provide a summary of the Pilot findings, program update on how researchers can access commercial data and a tutorial on the Smallsat Data Explorer (SDX) tool: Commercial Smallsat Brown Bag (PDF).
