GPS

GPS helps us to find the way at sea, on land and in the air. Satellites send out information about its time and position. The GPS receiver receives information from several satellites and in this way works out exactly where it is.

GPS was developed by the American military. In order to protect the technology it had an interference signal. During the Gulf War in 1990, the USA tracked the positions of its troops and targets in Iraq with GPS. The interference signal was turned off and for motorists and recreational sailors GPS positions suddenly got more precise.

Today there is GPS in every mobile telephone and there are even shoes which have GPS. In the future we will always know where we are — as well as Mum, Dad and Big Brother too.
