DESCRIPTION:How satellite navigation signal reflections can be used to hel
 p monitor the water cycle of the planet.\n\nSSTL\, part of the Airbus grou
 p\, is a UK spin-off company from the University of Surrey\, that designs\
 , manufactures and operates small satellites. Amongst its activities\, it 
 builds optical\, thermal and radar imaging satellites\, and is currently m
 anufacturing the Lunar Pathfinder mission offering communications links fo
 r lunar assets. Another SSTL project is the ESA HydroGNSS Scout mission wh
 ich comprises of two small satellites that will measure climate variables 
 using satellite navigation signal reflections. GNSS microwave signals are 
 continually being broadcast towards the Earth from over 100 satellites in 
 high orbits\, and are used for all kinds of navigation\, including militar
 y\, marine\, aircraft\, automotive and mobile phone use. Although these si
 gnals are very weak\, they reflect off the Earth’s surface and can be de
 tected by spacecraft in low Earth orbit and used as radar sources for sens
 ing geophysical properties of the Earth. HydroGNSS plans to use these refl
 ections to measure soil moisture\, inundation\, freeze/thaw\, and biomass\
 , with secondary measurements of ocean wind speed and sea ice extent\, all
  parameters important to sensing of our climate.\n\nFor more details\, and
