How are we different?

Advancing global weather awareness with space technology




Spire Global is at the forefront of the space frontier and innovation lies at the heart of its business model. Constantly innovating, Spire launches improved satellites every six months into space so as to increase its existing constellation and consequently, amplifying its ability to collect accurate observations from the upper echelons of the atmosphere. Using a technique known as radio occultation, Spire is able to gather over thousands of radio occultation measurements every 24 hours that enhance the value of its weather forecasts.

By running these RO (radio occultation) readings along with weather data from multiple sources, Spire creates weather forecasts that accurately predicts the weather impact on your operations.

This empowers you to make the best business decision possible.

What is Radio Occultation?

Radio occultation is a measurement that creates a detailed profile of conditions that extend from the Earth’s surface through the stratosphere and into the upper atmosphere (ionosphere). Radio occultation improves the accuracy of weather forecasts.




Spire Global collects thousands of these measurements each day. Low-Earth orbit satellites receive GNSS signals that have passed through and been refracted by the atmosphere. The level of refraction is dependent on the pressure, temperature, and water vapor concentration in the lower atmosphere and the electron density in the ionosphere. The radio occultation measurements scan the atmosphere vertically, providing a thorough picture of atmospheric conditions.

Today, RO (radio occultation) is used for remote sensing including weather forecasting, monitoring climate change, and space weather research. RO creates detailed measurements our atmosphere’s temperature, pressure, humidity, and electron density that is essential for tackling the planet’s current climate issues and monitoring both growth and development of new weather patterns.

What our customers say



storm cloud weather

“Rocket launches are extensively pre-planned for a specific outcome, where the launch window is calculated based on the location of the destination on its orbit. Weather events have a direct impact on the actual mission itself, therefore are monitored frequently within the site region. We expect that having access to the Spire Point Optimized Weather forecasts will increase our chances of performing a safe launch, leading to a successful mission, even in the most remote locations.”

Lloyd Damp
CEO – Southern Launch

“We’re a specialist company that does remote sensing, so we know the value that satellite technology brings to the table. This is why we’re so happy Spire provides such data points using satellite technology as it covers the entire world without any gaps. Before, the level of accuracy was only 75% but now with Spire’s integration, it’s gone up to 95%.”
