Hands up if you own one of these? (a GPS unit). If so, do you remember what life was like before you had one? I do. Painful. The low point for me came the day I got lost in Bedford. I had gone there for a meeting and forgot the location of the road. After a fruitless half an hour trying to find my way, I was ready to give up and drive home. Then James Hughes, the former curate, phoned. “Where are you” he said. “I don’t know” I replied.
“Let me help you” and he then proceeded to open up his computer which had street maps of England. Having identified the name of the road I was parked in and the name of the road I was heading for, he literally talked me there road by road, on my hands free phone, of course. That is what made me realize I needed a GPS. I never leave home without Sean Connery now – or at least a digitized version of Sean Connery’s voice. You know when you have arrived because he says “shaken not stirred”.
Do you know how GPS works? You turn it on and type in the post code. No, that is not what I mean. Do you know how it works? “When people talk about “a GPS,” they usually mean a GPS receiver. The Global Positioning System (GPS) is actually a constellation of 27 Earth-orbiting satellites (24 in operation and three extras in case one fails). The U.S. military developed and implemented this satellite network as a military navigation system, but soon opened it up to everybody else.
