One thing I do not understand. How is relativity important for GPS devices? If relativity did not exist then GPS devices would still work. They just need the speed of light to be less than infinite. In fact did the first software assume that relativity did not exist? But this gave errors which they fixed by adding in relativity?

Yes, because relativity exists they need to take it into account. But relativity it did not exist then GPS would still work.

I do agree that because relativity does exist it must be taken into account.
