Advanced Earth Intelligence

Access to environmental data in unprecedented detail, from Earth’s surface to near-space.

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.

Largest constellation of multifunctional nanosatellites

Fully deployed satellite constellation covering multiple orbital planes and replenished at every rideshare launch opportunity, enabling reliable worldwide coverage of its best-in-class, in-house designed STRATOS GNSS receiver.

Rich, unique datasets harness GNSS signals of opportunity

Spire’s STRATOS receiver has achieved several world firsts by collecting observations from multiple GNSS frequencies (L1, L2, L5, etc) and constellations (GPS, Galileo, GLONASS, BeiDou, QZSS), maximizing radio frequency (RF) diversity and quantity of observations.

Resilient observations and continuous technology improvement

A constellation of nanosatellites is inherently resilient to disruptions and our extensive ground station network enables reliable data downlinking. New and improved Spire nanosatellites are launched in batches multiple times per year.

Driving innovation with space-powered insights

The data we collect from Earth’s surface and atmosphere fuel groundbreaking research, spark new applications, and drive public environmental programs worldwide.

Surface data

We study Earth’s surface using GNSS scatterometry and precise altimetry (GNSS-R) to measure ocean wind speed, soil moisture, flood inundation, and sea ice.

Atmospheric data

Spire monitors our atmosphere with precise GNSS Radio Occultation (GNSS-RO) soundings to improve global weather forecasting accuracy.

Space weather data

We monitor the ionosphere using measurements of electron density and scintillation to augment GNSS accuracy, allowing you to prepare for and react to weather events in space.

Redefining data science with space-based innovation

Weather Forecasting

Revolutionizing weather forecasting

Spire Global is transforming weather forecasting with GNSS Radio Occultation (RO), a groundbreaking technology that enhances forecast accuracy in the short, medium, and long-range. As the leading commercial provider of RO data, Spire’s proprietary STRATOS GNSS payload generates thousands of high-resolution atmospheric profiles daily, offering unmatched global coverage and precision to meet the demands of modern meteorology.

NASA independently validated Spire’s GNSS Radio Occultation (RO) data, confirming its comparability to leading systems and its ability to fill data gaps, deliver fine vertical resolution, and penetrate atmospheric layers crucial for climate research. Spire is now advancing RO technology with polarimetric antennas, enabling precise measurements of precipitation and cloud properties. These innovations further improve Numerical Weather Prediction (NWP) models, enhancing weather and climate forecasting.

Spire is advancing GNSS technology to new frontiers with GNSS Reflectometry, delivering precise monitoring of ocean surface winds, waves, and other critical variables like soil moisture that significantly enhance weather forecasting. Furthermore, Spire is pioneering the use of Hyperspectral Microwave Sounders to gather highly detailed water vapor and temperature data, unlocking unprecedented accuracy in Numerical Weather Prediction (NWP) models.

Climate

Advancing climate insights

Polar regions are among the most vulnerable to climate change, experiencing the highest long-term temperature fluctuations, according to the IPCC. Spire Global has advanced its GNSS Radio Occultation (RO) processing to include surface reflection measurements of these critical areas.

Spire’s sea ice classification products demonstrate strong alignment with other ancillary institutional sensors, offering reliable insights for monitoring polar environments. Additionally, GNSS signal phase data enables the detection of relative sea ice height with remarkable accuracy, within 10 cm. With unmatched spatial and temporal coverage, Spire’s technology enhances existing climate missions, providing a critical tool for understanding polar dynamics and augmenting global climate monitoring efforts.

Soil moisture

Real-time soil moisture monitoring

Soil moisture plays a vital role in understanding climate dynamics, influencing agriculture, drought prediction, and ecosystem health. Spire Global leverages GNSS Reflectometry to deliver high-resolution soil moisture data with unparalleled accuracy and global coverage. By analyzing reflected GNSS signals, Spire’s technology provides real-time data on soil moisture levels, even in remote and challenging regions.

These insights empower industries such as agriculture, water management, and renewable energy to optimize operations, mitigate risks, and adapt to a changing climate. Discover how Spire’s innovative Soil Moisture Insights are driving meaningful climate intelligence.

Space weather

Ensuring resilience with space weather data

Spire’s space weather observations enhance GNSS reliability by monitoring ionospheric disruptions in real-time, as noted by NOAA, and ultimately ensuring safer navigation for autonomous vehicles, electrical grid security, and other critical applications. Researchers have also recognized the accuracy and value of Spire’s Precise Orbit Determination data, which can be used to enhance thermosphere modeling, enabling satellite operators to improve their path prediction and space situational awareness.
