Advanced Earth Intelligence
Access to environmental data in unprecedented detail, from Earth’s surface to near-space.
Scanning the Earth, 24/7
Spire constantly collects rich and unique data sets about our planet’s surface and its atmospheric layers to provide a complete view of what’s happening on and around Earth. Our low-orbit nanosatellites use radio frequency sensors to constantly gather new information, while predictive models distill complex environmental data into intelligent insights you can use to make business decisions, drive public initiatives, and anticipate future climate fluctuations.
What sets us apart?
Largest constellation of multifunctional satellites
Rich, unique datasets harness GNSS signals of opportunity
True global coverage with dense spatial and temporal resolution
Resilient observations and continuous technology improvement
Strong partnership and collaboration mindset
The data we collect on the Earth and its atmosphere fuels key research and development programs, inspires new services and applications, and drives public environmental programs across the globe.

Unique Earth data, from beneath the surface to the edge of space
Earth’s surface data sets
GNSS scatterometry and precise altimetry (GNSS-R):
- Soil moisture
- Sea ice classification & altimetry
- Surface water mapping – river, wetlands, flooding (under development)
- Ocean winds & waves (under development)
GNSS-RO profiles for improved weather forecasts and accuracy:
- Bending angle profiles
- Dry temperature profiles
- Refractivity profiles
Space weather & space situational awareness data
GNSS-based ionospheric monitoring:
- Total electron content (TEC) data
- Electron Density profile
- Ionospheric scintillation indices (ISI)
- Modeled ionospheric now and forecasts (under development)
- Precise orbit determination (POD)
Our data assessments
Our RF-based Earth Intelligence data has been evaluated and successfully validated as part of assessment studies carried out by established global and national scientific agencies, including NOAA, NASA, ECMWF, and UK Met Office.
“Based on the results of the technical evaluation of the data provided in the CWDP Round 2 Pilot, NOAA has concluded that the commercial sector is capable of providing the quality of data needed to help support NOAA’s operational weather forecasting needs.” As a result, NOAA is proceeding with plans to acquire commercial [radio occultation] data for operational use.”
