Satnav technology could save precious water
A group of farmers in the USA have a problem: for many years they have been using large amounts of water to grow crops in huge fields, but now their supply of water is running out. Help may come from an ESA spin-off technology that could help to preserve water supplies, while also making sure that crops do not go thirsty!
The plan comes from a former ESA employee called Javier Marti. He realised that some fields are watered too much, which is very wasteful. Could there be a way to use satellites to see which fields really need water? Javier thinks so!
If Javier’s idea works then it could be used around the world to help save water, all thanks to satellites that are already in orbit around Earth.
Cool fact: Analysing reflected satnav signals is a breakthrough technology, and over the next few years we may see many more uses for it!
