Free Data Access for Researchers – NASA CSDA Program
NASA recently awarded Spire a contract renewal to provide Earth observation data through the Commercial Smallsat Data Acquisition (CSDA) Program. We provide unique Earth intelligence data that is currently available to all U.S. Government-funded researchers at no cost.
The CSDA Program evaluates and procures data from commercial sources that support NASA’s Earth science research and application goals.
Through the program, all US Government-funded researchers, including NASA, are able to access Spire’s Earth Information data including:
- GNSS Radio Occultation (GNSS-RO) atmospheric profiles
- GNSS grazing angle reflectometry
- Space weather measurements
- Total electron content
- Ionospheric density profiles
- Satellite Precise Orbit Determination (POD) and satellite attitude
- Magnetometer observations

Leveraging Spire Data
Introducing the Spire Indri
The Low-Earth Multi-Use Receiver (LEMUR) is Spire’s signature 3U CubeSat platform used to collect the datasets offered through the NASA CSDA Program. Spire is a company committed to creating a safer, cleaner, and more sustainable world and the LEMUR is not only a creative acronym, but an opportunity to bring awareness to an endangered species of mammal threatened by climate change and destructive human activity.
The Indri is the largest living lemur (about 2 ft. long) located in the remote areas of northeastern Madagascar. It jumps from tree to tree in an upright position and rarely comes to the ground. The Indri is a critically endangered species, protected by law, suffering habitat loss due to slash-and-burn agriculture, fuelwood gathering, and logging.
