GNSS Remote Sensing:Overview and selected recent developments
Ponencia expuesta online en el 8th International Radio Occultation Working Group Meeting (2021) celebrado del 7 al 9 de abrilGround and satellite based GNSS Remote Sensing (GNSS-RS) developed during the recent
two decades into a very powerful and versatile tool for Earth System Research. A highlight of
these developments is the operational use of spaceborne GNSS Radio Occultation (RO) data
from several satellite missions to improve day-by-day global weather predictions.
GNSS Remote Sensing is briefly introduced with selected applications. One prominent
example is the improvement of regional and global weather forecasts. GNSS signals, reflected
from water, ice and land surfaces (GNSS-Reflectometry, GNSS-R) can usefully complement
the observation capabilities of GNSS-RO mission and enable versatile additional geophysical
applications such as observation of wind speed and precipitation over oceans, which are
illustrated. Finally, selected aspects for a comprehensive GNSS based Earth Observation with
small satellite constellations are presented
