Commercial Datasets
NASA's Commercial Smallsat Data Acquisition (CSDA) Program evaluates and procures data from commercial vendors that advance NASA’s Earth science research and applications activities.
Currently, all CSDA data acquired from Planet, Maxar (formerly DigitalGlobe), and Spire Global Subsidiary, Inc., are available to government users. An initial release of a subset of the EarthDEM products, developed by the Polar Geospatial Center, is also available. Data from the Teledyne Brown Engineering DLR Earth Sensing Imaging Spectrometer (DESIS) also are available through a separate collaboration with the International Space Station (ISS). See the table below to learn how to access vendor-specific data. All data products are available through CSDA at no cost to authorized researchers and are subject to scientific use licenses.
The commercial data currently distributed by NASA are available under different scientific use licenses and various access portals. Please see table below for data access portals and vendor-specific end user license agreement (EULA) information. Check back for updates on new data acquisitions.

Spire

Spire designs, builds, and operates a growing constellation of over 120 3U Low Earth Multi-Use Receiver (LEMUR) satellites tasked with collecting Radio Frequency (RF) signals from low Earth orbit. The company offers a suite of commercial RF sensing products, including a catalog of atmosphere, ionosphere, and weather data services derived from Global Navigation Satellite System (GNSS) signals collection.
The Spire-designed STRATOS payload collects these GNSS signals from which Spire can derive useful Earth Observation data types for climate and space weather research, among other applications. To support their mission, the company owns and operates over 30 ground stations and a robust data pipeline for quickly and securely moving data from orbit to cloud.
