Innovative British-built mission starts launch preparations
Preparations for the launch of a European Space Agency mission that will investigate Earth’s water cycle are underway, following the transportation of the two-satellite system from the UK to the US.
HydroGNSS is backed by the UK Space Agency and was manufactured by Surrey Satellite Technology Ltd (SSTL) in Guildford. It is part of ESA’s scout framework, which enables the rapid and cost-effective development of novel Earth observation technologies.
Consisting of two microsatellites, the mission will employ an innovative technique named Global Navigation Satellite System (GNSS) reflectometry – this approach monitors changes in satellite navigation signals caused by the physical properties of terrain, ice, oceans or vegetation and can provide scientific data on the water cycle.
Observations will be delivered on several key hydrological parameters, which can be used to assess climate risks as well as to support scientific and operational applications – such as weather forecasting or flood prediction.
HydroGNSS is expected to launch later this year from California aboard a Falcon 9 rocket.
Beth Greenaway, Joint Head of Earth Observation and Climate at the UK Space Agency, said: “The arrival of HydroGNSS in California marks an exciting milestone for UK space capabilities and our contribution to vital climate science. These satellites, built by SSTL, showcase the innovation and technical expertise of the UK space sector.
“HydroGNSS will provide crucial data on our planet's water cycle delivering valuable insights for environmental monitoring and water resource management.”
Pete Garner, Senior Project Manager, SSTL, said: “We’re thrilled to see HydroGNSS reach this key milestone as the satellites have now arrived safely in the USA and they await transport to the launch site to begin their integration campaign. This marks the culmination of hard work and collaboration by the entire team, and we’re looking forward to seeing the mission deliver vital climate data from orbit.”
