HydroGNSS Workshop Session Videos

SSTL recently hosted a popular online ESA Scout HydroGNSS Workshop attended by an average of 175 participants across 2 days of presentations.  We are pleased to share the session recordings with you - please either visit the HydroGNSS Workshop playlist on our YouTube channel, or watch the sessions via the embedded videos below.

What is the ESA Scout HydroGNSS mission?

HydroGNSS is the second mission in the ESA Scout programme, demonstrating Earth Observation science with a small budget and rapid schedule.  HydroGNSS is a 55kg satellite that will take measurements of key hydrological climate variables, including soil moisture, freeze thaw state over permafrost, inundation and wetlands, and above ground biomass.  It uses a technique called GNSS Reflectometry that exploits signals from Global Navigation Satellites Systems as radar signal sources.  These signals reflect off the land, ice and ocean and are used by a low power receiver in Low Earth Orbit to yield important geophysical measurements. 

Who is the Workshop aimed at?

This workshop is aimed at potential users of HydroGNSS measurements for climate and meteorological models, researchers working in complementary EO missions, and those with an interest in GNSS reflectometry as a future Earth observation technique sustainable through the use of small satellite constellations. 

Day 1, Session 1: Introduction to HydroGNSS

This video covers an introduction to the HydroGNSS mission and keynote speeches from Maurice Borgeaud, Head of Science Apps and Climate at ESA, Dominique Gillieron, Head of Earth Explorer Programme at ESA, Beth Greenaway, Head of EO and Climate at the UK Space Agency, Sir Martin Sweeting, Executive Chairman at SSTL, Manuel Martin Neira, Principal Engineer at ESA, Martin Unwin and Peter Garner, HydroGNSS Mission Leads at SSTL.

Day 1, Session 2: HydroGNSS Data Products

This video covers HydroGNSS Data Products and how the satellite will collect parameters closely connected with Essential Climate Variables (ECVs) with details of soil moisture, inundation, freeze/thaw and biomass, ocean wind speed and sea ice extent.

Speakers: Nazzareno Pierdicca at Sapienza, Kimmo Rautiainen at FMI, Estel Cardeilach at ICE-CSIC/IEEC, Emanuele Santi at IFAC and Guiseppe Foti at NOC.
