GPS Takes Us Further Than From A to B

Back in the 1960's it was initially developed by the US space programme and used by the US military against the USSR during the cold war. The system contains over 25 satellites placed around the planet. They send information signals containing time and geographical code which are picked up by receivers in order to plot a specific place on earth. In the 1980's gps software became available for civilian use.

By far the most common use in the world today is car satellite navigation (sat nav). Engineers used gps maps to developthese black boxes that we seen on millions of car dash boards. These handy devices help drivers plot routes around the country and in fact many have global capacity and have undoubtedly helped cross country travel. As the receivers and maps have developed to match the capabilities offered by system, it has given drivers the opportunity to find alternative routes around imminent traffic jams; alerts them of speed cameras and shows points of interest for convenience

Drivers utilise this technology the most, but aircraft and shipping vessels also employ gps systems for speed and location accuracy. Over the last two decades it has also had a positive effect in other areas of everyday life. For example the emergency services use GPS to locate accidents, plot the quickest route and have specific information enabling back-up staff to find the scene quickly and efficiently. It has been attributed to save lives when rescue teams are faced with extreme weather such as on sea or on the moors where time is of the essence. In fact it has become a crucial piece of hiking gear not only for emergency tracking but also means they can check they are on the right path and create rendezvous points along the way.

Another area it has become vital is within scientific geological research. It can be used for monitoring the movements of the earth and by using the map give important data about earth quakes and volcanoes. Furthermore, it can be strategically used to track new phenomena such as climate change.

Receivers have developed so rapidly that they are now found within a pda phone. This has meant that it can also be used for leisure activities such as geocaching; essentially this is a digital treasure hunt with gamers using precise gps signals to find the prize. As we integrate gps into our daily lives it seems we are finding more and more uses for this versatile software.
