Chris Budd: “Space science is one of HM Government’s ‘eight great technologies’. In this lecture I will explain the mathematics behind satellites, showing how they are controlled, how they are sent to distant planets and how they transmit and receive data over vast distances. 

I will also explain how GPS systems work and show how General Relativity plays a vital role in making GPS systems so accurate. I will finish by showing a link between space science and Origami.
