Estimating Wave Direction Using Terrestrial GNSS Reflectometry [PDF]

open access: yesRemote 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

PRETTY – passive GNSS-Reflectometry for CubeSats [PDF]

open access: yese & i Elektrotechnik und Informationstechnik, 2022
AbstractThe Passive Reflectometry and Dosimetry (PRETTY) is a small satellite mission developed by a consortium consisting of RUAG Space GmbH (RSA), Graz University of Technology (TUG), and Seibersdorf Laboratories (SL). The primary objective of the passive altimetry within the PRETTY mission is to measure the ice and sea ice surface elevation and ...
