PlanetiQ supplies GNSS radio occultation data through NASA CSDA

PlanetiQ provides Global Navigation Satellite System (GNSS) Radio Occultation (RO) data through NASA's Commercial Satellite Data Acquisition (CSDA) program to support weather and climate forecasting and modeling, as well as space weather. PlanetiQ's satellites carry the "Pyxis" RO sensor, capable of receiving signals from all four global GNSS constellations: GPS (U.S.), GLONASS (Russia), Galileo (Europe), and Beidou (China).

The Pyxis sensor delivers high signal-to-noise ratio (SNR) GNSS-RO data with very high vertical resolution that can enhance observations of Earth's atmosphere, including into the lower troposphere and boundary layer, where the majority of atmospheric water vapor resides and most weather occurs.

The PlanetiQ data acquired by CSDA includes: Neutral Atmospheric Refractivity Retrieval; Ionosphere Scintillation Calibrated Phase; Ionosphere Total Electron Content; and Neutral Atmosphere Calibrated Phase. All members of the U.S. Government, and researchers funded by the U.S. Government, have access to the PlanetiQ GNSS-RO data products.

To request access to CSDA-distributed data, complete the CSDA Authorization form; the CSDA team will verify if the user is authorized. Data products and derivatives for imagery must contain the specified copyright markings: for data products, "© PlanetiQ YYYY.
