HI THERE HERE IS A LITTLE INFO ON SAT NAV / GPS I HOPE IT HELPS THANKS FOR LOOKING

WHY DO I WANT SAT NAV?

I guess that everyone has to ask himself or herself that question at some stage in the process, and it's as well to know the answer, if only to explain why it's more important to buy a GPS system than it is to purchase a new washing machine or some other essential that's a touch more fundamental to ongoing life.

So what is the answer?

Well it can vary — all of my mates have got one, I am a serious walker or climber, I regularly travel on business, I'm embarking on a long distance touring holiday; I've got a boat and so on and so on. The reality is that there are so many uses and applications for GPS systems it's a wonder everyone hasn't got one already. Certainly once it becomes a part of your life you'll be amazed at how you ever managed without it.

Let's try and work through the process


What would I use it for?

The uses for a GPS system are limited only by the imagination…

The fundamental property of a GPS system is to utilise the Global Positioning System (GPS) satellites to determine the users exact position at any given moment in time. If that positioning ability is then coupled with software that processes the information all sorts of possibilities open up.

Walkers and climbers can obviously use a GPS system to determine their current position; they can log that position and by use of a compass return to that same spot with a high degree of accuracy. It's worth noting that a number of GPS systems have a built in compass — some even have a built in barometric altimeter! We'll look at some of those later on.

Drivers can use mapping and navigation software to superimpose their position onto a map and through the navigational part of the software, determine the routing to another location.

Sports persons can determine their speed and direction as their GPS system measures the time taken to travel between points and utilises software to make the calculations.

Golfers, although not in competitions, can determine exactly where they are on a hole relative to the centre of the green or some other pre-programmed point.

And so it goes on, the GPS unit determines the current position and the application software stores that information and uses it to make calculations that in turn deliver information in a format useful to the user.

There is a major decision that needs to be taken at an early stage in the buying decision process otherwise the choice will be overwhelming. It really relates around the hardware and software options that are available and the application you are interested in.
