Description

GPS was the first global Satellite Navigation System; now there are four - why so many? To work they need to know the positions of many orbiting satellites accurately – why was such a challenging method chosen? Each satellite transmits lots of signals – why? Receivers have shrunk from tall cabinets to handheld devices – but there are still challenges.

Professor Macleod will explain how smartphone SatNav uses tricks to work faster and save power and describe how the uses of SatNav have grown far more than was ever envisaged. But SatNav technology has limitations – such as its limited accuracy and its susceptibility to interference and he will discuss how new receiver technologies are combatting those.
