Can GNSS reflectometry detect precipitation over oceans? [PDF]

Geophysical Research Letters, 2018
For the first time, a rain signature in Global Navigation Satellite System Reflectometry (GNSS‐R) observations is demonstrated. Based on the argument that the forward quasi‐specular scattering relies upon surface gravity waves with lengths larger than ...

Software tools for GNSS interferometric reflectometry (GNSS-IR) [PDF]

GPS Solutions, 2018
GNSS-R interferometric reflectometry (also known as GNSS-IR, or GPS-IR for GPS signals) is a technique that uses data from geodetic-quality GNSS instruments for sensing the near-field environment. In contrast to positioning, atmospheric, and timing applications of GNSS, GNSS-IR uses the signal-to-noise ratio (SNR) data.

Estimating Wave Direction Using Terrestrial GNSS Reflectometry [PDF]

Remote Sensing, 2019
The signal-to-noise ratio (SNR) data are part of the global navigation satellite systems (GNSS) observables. In a marine environment, the oscillation of the SNR data can be used to derive reflector heights. Since the attenuation of the SNR oscillation is
