The National Oceanic and Atmospheric Administration (NOAA) has taken a significant step towards enhancing its weather forecasting and space weather prediction capabilities by awarding contracts to Spire Global and PlanetiQ for radio occultation data. On December 1, 2026, NOAA announced that it had awarded $3.7 million to Spire Global and $2.7 million to PlanetiQ for the provision of radio occultation data, which will be used to improve the accuracy of weather forecasts and space weather predictions.
Radio occultation is a technique used to measure the atmosphere by analyzing the bending of radio signals as they pass through it. This technique utilizes Global Navigation Satellite System (GNSS) signals, such as those provided by GPS, to determine the properties of the atmosphere, including temperature, pressure, and humidity. By analyzing the bending of these signals, scientists can gain valuable insights into the state of the atmosphere, which is essential for accurate weather forecasting.
Spire Global will provide NOAA with 4,600 daily GNSS profiles and 1,200 temporal resolution enhancements, while PlanetiQ will deliver 4,200 GNSS profiles and 500 total electron content tracks per day. The total electron content (TEC) is a measure of the number of electrons in the ionosphere, which is crucial for space weather forecasting. Space weather events, such as solar flares and geomagnetic storms, can have significant impacts on satellite communications, navigation, and other technologies.
The contracts awarded to Spire Global and PlanetiQ are part of NOAA's efforts to establish an indefinite delivery, indefinite quantity (IDIQ) contract vehicle, which is expected to have a ceiling of $2.35 billion over 10 years. This contract vehicle will enable NOAA to procure radio occultation data from multiple vendors, providing the agency with flexibility and redundancy in its data collection capabilities.
The significance of these contracts extends beyond the immediate benefits to NOAA's weather forecasting and space weather prediction capabilities. The use of radio occultation data has the potential to revolutionize the field of meteorology, enabling scientists to gain a more detailed understanding of the atmosphere and its dynamics. Furthermore, the development of commercial radio occultation constellations, such as those being built by Spire Global and PlanetiQ, is expected to drive innovation and reduce costs in the aerospace industry.
In conclusion, the awards of contracts to Spire Global and PlanetiQ mark an important milestone in NOAA's efforts to improve its weather forecasting and space weather prediction capabilities. The use of radio occultation data has the potential to transform our understanding of the atmosphere and its dynamics, and the development of commercial radio occultation constellations is expected to have a significant impact on the aerospace industry.
