Scanning the earth, 24/7

Spire constantly collects and enriches data about our planet and its atmosphere to provide a complete view of what’s happening on Earth. Low-orbit nanosatellites use radio frequency sensors to gather new information over 10,000 times a day, 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.
