GNSS-IR for Environmental Sensing
Session ID#: 248615
Session Description:
GNSS Interferometric Reflectometry (GNSS-IR) is an emerging remote sensing technique that uses the interference between direct and coherently reflected GNSS signals. This technique has been applied to measure a variety of variables including water level, significant wave height, snow accumulation, ice freeboard, permafrost thaw, soil moisture, vegetation water content, and coastal subsidence. As the number of developers and users continues to grow, this session seeks to highlight advances in the (near real-time) acquisition, processing, analysis and application of GNSS-IR in environmental sensing. The session welcomes contributions related to the algorithmic and technical improvement of GNSS-IR models, as well as the development of open-source hardware and software. We also invite presentations of GNSS-IR delivery products and their validation, the optimal exploitation of geodetic and affordable GNSS sensors for GNSS-IR applications, and initiatives for (near) real-time monitoring of environmental variables.
