An investigation of atmospheric temperature profiles in the Australian region using collocated GPS radio occultation and radiosonde data [PDF]

, 2011
GPS radio occultation (RO) has been recognised as an alternative atmospheric upper air observation technique due to its distinct features and technological merits.

Ionospheric Disturbances in GNSS TEC Data: SpaceX Falcon 9 Deorbit Maneuvers Over CONUS in April–May 2024

Geophysical Research Letters
Traveling ionospheric disturbances (TIDs) driven by a large number of internal and external sources are detectable with dense networks of ground‐based Global Navigation Satellite System (GNSS) receivers' measurements of total electron content (TEC).

Sea Surface Height Inversion Model Based on Multimodal Deep Learning for the Fusion of Heterogeneous FY-3E GNSS-R Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Sea surface height (SSH) is of great significance in oceanography and meteorology. Traditional physical altimetry methods based on delay–Doppler mapping (DDM) are subject to errors that are difficult to correct computationally.

New applications and opportunities of GNSS meteorology

, 2020
Water vapor content of the atmospheric low layer, up to about 18 km, known as troposphere or neutral atmosphere, affects GNSS (Global Navigation Satellite System) signals by lowering their propagation velocities with respect to vacuum. A diminished speed results in a time delay in the signal propagation along the satellite-receiver path, that ...

Identification of ionospheric scintillation in the low-latitude African sector using a commercial CubeSat constellation

Journal of Space Weather and Space Climate
Radio occultation (RO) measurements performed by Global Navigation Satellite System (GNSS) receivers onboard low-earth orbit (LEO) satellites are commonly used for a variety of atmospheric applications, including ionospheric and space weather studies. We
