Time-domain Statistics of the Electromagnetic Bias in GNSS-Reflectometry [PDF]
Global Navigation Satellite Systems-Reflectometry (GNSS-R) is an emerging remote sensing technique that uses navigation signals reflected on the Earth’s surface as sources of opportunity for scatterometry and altimetry.

Estimating Wave Direction Using Terrestrial GNSS Reflectometry [PDF]
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]
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 ...

From GPS Receiver to GNSS Reflectometry Payload Development for the Triton Satellite Mission
The global positioning system (GPS) receiver has been one of the most important navigation systems for more than two decades. Although the GPS system was originally designed for near-Earth navigation, currently it is widely used in highly dynamic ...

Effective Surface Roughness Impact in Polarimetric GNSS-R Soil Moisture Retrievals
Single-pass soil moisture retrieval has been a key objective of Global Navigation Satellite System-Reflectometry (GNSS-R) for the last decade. Achieving this goal will allow small satellites with GNSS-R payloads to perform such retrievals at high ...

DME/TACAN Impact Analysis on GNSS Reflectometry [PDF]
Global navigation satellite system reflectometry (GNSS-R) is becoming a widely accepted technique for remote sensing. The interferometric technique (iGNSS-R) correlates the direct signal received from a satellite and the same signal reflected on the Earth's surface, whereas the conventional technique (cGNSS-R) correlates the reflected signal with a ...

An Introduction to the HydroGNSS GNSS Reflectometry Remote Sensing Mission [PDF]
HydroGNSS (Hydrology using Global Navigation Satellite System reflections) has been selected as the second European Space Agency (ESA) Scout earth observation mission to demonstrate the capability of small satellites to deliver science. This article summarizes the case for HydroGNSS as developed during its system consolidation study.
