PlanetiQ GNOMES-4 Satellite, with the World’s Most Accurate Weather Forecasting Sensor, Launches into Orbit aboard SpaceX Falcon 9 Rocket from Vandenberg Space Force Base in California

Fast Facts:

  • PlanetiQ data uniquely provides highly accurate global observations of the atmosphere and ionosphere measured via the company’s proprietary GNSS Radio Occultation (RO) measurements with uniquely high Signal-to-Noise Ratio (SNR)
  • GNOMES-4 is PlanetiQ’s next generation RO measurement satellite, equipped with the company’s proprietary Pyxis sensor technology – the highest sensitivity GNSS-RO instrument ever flown. Pyxis produces over 2200 soundings per day.
  • PlanetiQ data is most critical for predicting severe weather and climate as it can penetrate any type of weather down to the Earth’s surface and across the entire globe.

GOLDEN, Colo.–(BUSINESS WIRE)–PlanetiQ, a leading innovator of global atmospheric observing systems, has launched its fourth generation Radio Occultation (RO) measurement satellite, GNOMES-4, aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California. The satellite was successfully deployed into Low-Earth Orbit at 10:36 am PT on December 1, 2023.

GNOMES-4 is equipped with the world’s best weather sensor, a PlanetiQ-proprietary technology sensor called Pyxis, which enables PlanetiQ to offer the highest quality GNSS-RO data for enhanced weather forecasting and atmospheric research to both government and commercial customers, such as airlines, insurance, energy, agriculture and financial services.. The data produced are temperatures, pressures and water vapor readings, similar to what a weather balloon would produce, but adds the critical capability of obtaining data over the entire globe, not just land, for better initialization of the global weather forecasting models.

Pyxis, a fourth-generation radio occultation (RO) sensor, is smaller, lighter, consumes less power and has nearly three times the data collection capability than previous versions. Pyxis receives signals from all four world-wide GNSS constellations (GPS, GLONASS, Galileo, and Beidou), and is powerful enough to provide more than double the amount of data available from the next-best GPS-RO sensors currently on orbit. Pyxis also is capable of routinely probing down into the lowest layers of the atmosphere where severe weather occurs.

PlanetiQ is the only system capable of profiling the thermodynamic state of the atmosphere with very high vertical resolution, precision and accuracy routinely down to the surface under any and all weather conditions, over any type of surface, across the globe.

In September 2023, PlanetiQ, was selected by NASA to supply their highest quality GNSS-Radio Occultation data to enhance capabilities in weather and atmospheric research. PlanetiQ was one of seven companies selected through NASA’s CSDA Program, which has allocated $476M for commercial data over the next five years.

In July, 2023, PlanetiQ began daily delivery to NOAA of their highest quality SNR GNSS-Radio Occultation data under NOAA’s IDIQ-2 operational Delivery Order-2. This data is used by NOAA to improve our environment and save lives with superior weather forecasting and atmospheric research.

About PlanetiQ

The mission of PlanetiQ is to bring innovation to the global atmospheric observing system at low cost, via high performance GNSS and related observations to fill the urgent need for highly accurate data to build predictive weather models that can save lives and provide a more environmentally secure future for our planet. The company, founded in 2015 and privately owned, is building, launching, and operating a commercial constellation of the highest quality HD GPS-RO weather satellites, with an eventual full constellation of 20 Low Earth Orbit (LEO) satellites.
