A team of students from Shrewsbury school has won a contest to design an experiment that will fly on a British-built satellite in 2010.
Their winning entry is a small instrument called POISE, which will measure variations in the ionosphere - the outermost layer of the atmosphere.
These variations can affect the accuracy and safety of satellite navigation (sat-nav) systems.
