Spire Global satellite constellation still

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.

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.”
