GPS has been in my family since the 60's.
My father was in the RAF and he worked on Radar systems, he spend 2 years working with the Americans in the US and on Ascension Island in the 60's when they were mapping the world for the GPS system. They were pinging signals via Echo 1 (and later to Echo 2 also) to trucks (moving slowly round the world) to the receiving stations - such as Ascension Island.
Little did he know that some 40 years later his son would have (like many of us) a GPS receiver in the car.
Now what has prompted this - well I've just I loaded some new TomTom voices into my Pocket PC, Joanna Lumley, Jean Luc Picard, Michael Caine, John Cleese, Homer Simpson and Ozzy Ozbourne (Only to be used when the kids are not in the car!)
I chuckled all the way to and from the supermarket - it's the little things of life
