Radio Occultation Technology,
significantly enhancing weather
The radio occultation profiles collected by Spire's satellites bring a unique understanding of the global weather conditions, and is the foundation of a highly valuable weather forecast.
How does it work?
1. GPS/GNSS Satellites
Spire satellites collect radio signals sent by GPS/GNSS satellites on the other side of the planet.
2. Radio Occultation
As these signals pass through the atmosphere, they are refracted.
3. Spire Satellites
By analyzing the refraction, Spire is able to understand the atmosphere from the ground up to 120 km.
Continuously enhancing weather forecasts with Spire’s unique technology.
What is the added value?
Radio occultations provide an unbiased very accurate measurement of the atmospheric conditions without variations over time and experimented with weather sensors.
Unlike weather balloons that only collect data twice per day from specific sites, Spire satellites scan the entire planet 24/7 and over remote regions like the oceans and the poles.
