Analysis of GNSS-R Coverage by a Regional Aircraft Fleet
IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020Airborne GNSS-R instrument systems are typically only utilized for a limited number of aircraft flights to perform experiments, to test new instruments, and to collect data over specific targets (e.g. hurricanes). A new system is currently under development entailing the permanent installation of GNSS-R instruments on a commercial fleet of Air New ...

Considerations on Gnss-R Carrier Phase Altimetry
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018The European Space Agency has recently studied, assessed or approved GNSS Reflectometry mission concepts based partly or fully on carrier phase observables for altimetry applications. Examples of these are, respectively, the GEROS-ISS experiment on board the International Space Station, the G- TERN Earth Explorer proposal or the PRETTY cubesat mission,

Cryospheric Sensing Using GNSS-R
2013Snow and ice on the land are important components of climate systems and a critical storage component in the hydrologic cycle as well. However, in situ observations of snow distribution are sparse, and remotely sensed products are imprecise and only available at a coarse spatial scale.

Analysis of GNSS-R delay and Doppler tracking errors
2012 Workshop on Reflectometry Using GNSS and Other Signals of Opportunity (GNSS+R), 2012The compensation of the delay and Doppler errors using tracking is important to accurately estimate the sea height in spaceborne GNSS-R. This work presents the impacts of the tracking residual errors on the GNSS-R observables, and potential tracking strategies for spaceborne GNSS-R.

A GNSS-R experiment over wave channel surface
2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013This study presents the feasibility of sea waves monitoring using the P(Y) & C/A ReflectOmeter (PYCARO) instrument which employs a novel Global Navigation Satellite Sys tems Reflectometry (GNSS-R) correlation technique. To that end, an experiment over the wave channel surface of the civil engineering school of UPC (Barcelona, Spain) is performed using ...

A GNSS-R Geophysical Model Function
2020A machine learning technique is implemented for retrieving space-borne Global Navigation Satellite System Reflectometry (GNSS-R) wind speed. Conventional approaches commonly fit a function in a predefined form to matchup data in a least-squares (LS) sense, mapping GNSS-R observations to wind speed. In this study, a feedforward neural network is trained
