Weather Forecasting

Weather forecasting impact with radio occultation

GNSS Radio Occultation (RO) profiles are a key input to all weather forecasting systems, providing significant improvement to long-term forecast accuracy. Using a proprietary GNSS payload called STRATOS, Spire miniaturized and commercialized the technique, becoming the world’s first commercial producer of RO measurements. Today, Spire is the world’s largest producer of RO data.

An independent assessment of Spire RO from NASA concluded it is “of quality consistent with the other GNSS-RO observing systems […] in terms of their weather forecast impact, and the spatial distribution was complementary in filling data void regions. Vertical information content was suitable for studying the fine structures and seasonal variabilities of the tropopause, and their penetration depth was very good and may be useful in the study of the planetary boundary layer.”

Ocean & Climate

Rapid development of ocean monitoring using spire SDRS

Spire adapted its existing radio occultation instruments in space to perform the first dual-frequency, grazing angle GNSS-R altimetry measurements of the ocean. NASA performed an independent evaluation of the Spire data and found that “The GNSS reflected measurements show promise to measure sea surface height with a precision of 2.5 cm over 1 sec averages 
and an accuracy of < 10 cm.”

In collaboration with NOAA, Spire is now working on a follow-on project to produce the ocean altimetry measurements and use 
it to monitor coastal sea levels and the extent of sea ice in 
polar regions.

Space-situational awareness

Increasing space-situational awareness with Spire 
pod data

NASA found that Spire POD data was “useful in retrieving thermosphere density via satellite drag – particularly in quantifying day-to-day variability.” With improved thermosphere modeling, operators and governments can more effectively predict the paths of spacecraft in low-Earth orbit and improve operator safety.

Autonomous vehicles

Enhanced GNSS integrity with ionospheric monitoring

Businesses and individuals are increasingly reliant on GNSS technologies for daily life and operational success across a 
wide range of industries, in particular for autonomous vehicles. However, GNSS technology can be disrupted by the ionosphere, and existing terrestrial and satellite systems are not 
able to provide global monitoring on the time-scales of 
the disturbances.

By monitoring and correcting these disturbances, autonomous vehicles can work more safely and with higher availability. 
In collaboration with the European Space Agency, Spire is developing a real-time ionospheric mapping system using 
Spire ionospheric data.
