GNSS Radio Occultation in Advanced Numerical Weather Prediction Models
GEOmedia, 2019 GPS-Radio Occultation (GPS-RO), and generally, Global Navigation Satellite System Radio Occultation (GNSS-RO), is a technique that measures the refractivity of the Earth's atmosphere as a Low Earth Orbit (LEO) satellite listens to the radio signal of a ...

Assessment of ZTD Derived from COSMIC Occultation Data with ECWMF, Radiosondes, and GNSS [PDF]
Sensors, 2022 Global Navigation Satellite System (GNSS) signals generate slant tropospheric delays when they pass through the atmosphere, which is recognized as the main source of error in many spatial geodetic applications. The zenith tropospheric delay (ZTD) derived

Retrieval of the Stratospheric Density by the Star Occultation
Aerospace, 2023 The navigation by the stellar refraction is important for a LEO (Low-Earth-Orbit) satellite, especially in a GNSS (Global Navigation Satellite System)-denied environment, since it is totally autonomous.

High-order ionospheric effects on electron density estimation from Fengyun-3C GPS radio occultation [PDF]
Annales Geophysicae, 2017 GPS radio occultation can estimate ionospheric electron density and total electron content (TEC) with high spatial resolution, e.g., China's recent Fengyun-3C GPS radio occultation. However, high-order ionospheric delays are normally ignored.
