TDS-1 GNSS Reflectometry

2018
This study presents the development and a systematic evaluation study of GNSS reflectometry wind speeds. After establishing a wind speed retrieval algorithm, UK TechDemoSat-1 (TDS-1) derived winds, from May 2015 to July 2017, are compared to the Advanced Scatterometer (ASCAT).

Ship detection using GNSS-reflectometry in backscattering configuration

2018 IEEE Radar Conference (RadarConf18), 2018
The chance of exploiting the Global Navigation Satellite Systems-Reflectometry (GNSS-R) remote sensing technology in the field of maritime surveillance and ship traffic monitoring has been explored in the very recent past. The conventional bistatic GNSS-R is based on the acquisition of GNSS navigation messages in a forward-scattering geometry, where ...

Wind retrieval for GNSS reflectometry from techdemosat-1

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
The main purpose of this study is to propose and validate a new algorithm for wind speed retrieval over the ocean using Global Navigation Satellite System-Reflectometry (GNSS-R). The proposed method is based on a Least Squares (LS) estimation from the volume of the scattered power function.

Experimental and modelled GNSS Reflectometry response over land

2018 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2018
The applications of spaceborne GNSS reflectometry data over land are investigated in this work using the data collected by the UK TechDemoSat experimental mission. In order to quantify the sensitivity of the GNSS reflections to biomass and soil moisture from real data it is necessary to extract a quantity, like the surface reflectivity, as much as ...
