SL variations at diurnal and longer periods were also well captured by all series. Semidiurnal tidal constituents showed good agreement between TG and all GNSS-R groups. SNR data for the GPS L1-C/A signal were processed by four groups, in Sweden, Luxembourg/Brazil, Germany, and the UK. Data collected at the Onsala Space Observatory for a 1-year period (2015–2016) were compared to a co-located tide gauge (TG). This action was an initiative of the International Association of Geodesy working group 4.3.9 (2015–2019 term). The goal was to cross-validate retrieval solutions from independent research groups under comparable conditions. ![]() We report results from the first inter-comparison campaign on SNR-based GNSS-R. Of particular interest is the exploitation of existing coastal GNSS sites for reflectometry by means of signal-to-noise ratio (SNR) observables. ![]() SL has immense societal implications related to climate change. Ground-based Global Navigation Satellite System Reflectometry (GNSS-R) is quickly maturing toward the objective of becoming a viable alternative for operational coastal sea-level (SL) altimetry in a geocentric reference frame.
