Non-Euclidean geometry is essential to the theory of general relativity, which is of immense use in astronomy and also allows the GPS system to function accurately.

What is astronomy used for?
and also allows the GPS system to function accurately.
General relativity does. Non-Euclidean geometry does not. I'm pretty certain you can approximate it well enough with Euclidean geometry. Gravitational time dilation is just a function of hight.
Also, GPSs already work. There's no need for me to use non-Euclidean geometry.
Finally, that was just an example. If someone is interested in pure mathematics, and there's a...
