The Only Commercial Satellite Weather Data


Critical Weather Data

GPS Radio Occultation (GPS-RO) data “supercharges” forecasting models. Each occultation provides an incredibly accurate depiction of a slice of the atmosphere. When fed into existing models, this data increases short term forecast accuracy.

Fully Processed In-house

Spire has built the world’s first commercial radio occultation processing system. Each of the profiles that you see below were collected with a Spire satellite and processed with Spire’s processing system.



By utilizing a network of tens or hundreds of CubeSats with radio occultation payloads, the number of opportunities to receive radio occultations increases dramatically. Increased RO data points results better forecasts.

You need fresh data no matter what time it is. That is why Spire operates teams on three continents. As the sun begins to set on one operations center, the sun is rising on another.

Extreme Weather on the Rise

Extreme weather threatens both lives and businesses. With the advent of climate change, extreme weather events continue to increase in frequency. Having adequate warning has never been more important.
