Sensitivity to soil moisture of spaceborne GNSS-R observables
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Restricted access - publisher's policyThe potential of GNSS-R techniques to estimate land surface parameters such as Soil Moisture (SM) is experimentally studied using 2014-2017 global data from the UK TechDemoSat-1 (TDS-1) mission. The approach is based on ... -
Antena Bi-banda con conformación de dos haces simultáneos para sistemas GNSS-R
(Unión Científica Internacional de Radio (URSI), 2018)
Conference report
Restricted access - publisher's policyGlobal Navigation Satellite Systems – Reflectometry (GNSS-R) is a relatively new remote sensing technique that benefits from GNSS signals as signals of opportunity as a bistatic radar. These signals can be processed as ... -
Microwave and optical data fusion for global mapping of soil moisture at high resolution
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Restricted access - publisher's policyAfter more than 8 years in orbit the Soil Moisture and Ocean Salinity (SMOS) satellite is still in good health and several algorithms for improving its spatial resolution have been proposed and validated in a variety of ... -
Instrument needs for the Copernicus space infrastructure in the timeframe 2020–2030
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Restricted access - publisher's policyThis work is part of “Operational Network of Individual Observation Nodes” (ONION). ONION is an H2020 project devoted to identify solutions and to satisfy emerging needs of the European Earth Observation (EO) market. In ... -
Preliminary end- to-end results of the MIR instrument: the microwave interferometric reflectometer
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Restricted access - publisher's policyGlobal Navigation Satellite Systems - Reflectometry (GNSS-R) has shown his potential for remote sensing. Since new wider band signals are being broadcasted, and new systems are becoming available, a performance comparison ... -
Spaceborne GNSS-R end-to-end simulator: topography and vegetation effects
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Restricted access - publisher's policyAs the TDS-1 and CYGNSS spaceborne GNSS-R missions progress, a large number of Delay-Doppler Maps (DDM) is being collected, from the land scattered as well as from the ocean. Based on those data, the feasibility study on ... -
RFI analysis and mitigation in airborne GNSS-R campaign
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Restricted access - publisher's policyRadio-Frequency Interference (RFI) is one of the most concerning topics in Global Navigation Satellite Systems (GNSS) and GNSS - Reflectometry (GNSS-R) because any undesired signal present at the antenna can corrupt the ... -

(European Space Agency (ESA), 2017)
Conference report
Open AccessEnd-to-end mission performance simulators for Earth Observation missions are one of the prominent tools for system design and scientific validation in early mission phases. The European Space Agency (ESA)has promoted efforts ... -
GNSS-R: a useful tool for sea target detection in near real-time
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Conference report
Restricted access - publisher's policyThis paper investigates a novel application of Global Navigation Satellite System-Reflectometry (GNSS-R) in the fields of maritime surveillance and safety, and climate change analysis, namely sea target detection in near ... -
Feasibility of RFI mitigation in synthetic aperture radiometery based on subspace spatial filtering
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Conference report
Restricted access - publisher's policyThe impact of Radio Frequency Interference (RFI) is a very serious problem for spaceborne microwave radiometry. Many Soil Moisture Ocean Salinity (SMOS) images show serious contamination by the RFI. SMOS is even more ...
