One of the biggest advances in modern technology has been the development of GPS systems which allow us to find our position to very high precision. GPS is just the latest advance in the science of navigation, which has had a profound effect on human civilisation.

This talk will show how mathematics has played a vital role in making navigation as accurate as it is today and the impact that this has had on us all. Indeed it is one of the few areas where Einstein's general theory of relativity directly impacts on our lives.
