The invention of GPS

There are few inventions that we rely on as much as the Global Positioning System, also known as GPS. But, when it was created in the late 1970s, nobody wanted it.Prof Brad Parkinson and his team at the US Air Force built it, and the first GPS satellite was launched in 1978. However, GPS wasn’t widely used until an air disaster in 1983 highlighted the need for satellite navigation. Nowadays, GPS helps countless people travel in the right direction. But, we also rely on it for many things you might not realise: it keeps aeroplanes in the sky, props up global trade, farming and construction, and even supports banking transactions. Ben Henderson speaks to Prof Parkinson, "the father of GPS".Eye-witness accounts brought to life by archive. Witness History is for those fascinated by the past.
