Modern auto navigation units are really fantastic. Have you ever thought about acquiring one? Those who do not have or have never had a modern auto navigation system, or GPS (Global Positioning System) as it is also known as. will probably not know quite how much knowledge they supply. It is no longer merely an item to prevent you from getting lost whilst you are travelling from A to B.
Far from it. Contemporary GPS systems will tell you if you are passing monuments, sites of historical importance or beauty, churches, hotels, restaurants, taverns, garages, petrol pumps, airports and practically anything else that you want it to inform you of. They have moved on from being only an on screen map to being a travel guide and much more..
If you are thinking about acquiring a GPS auto navigation system, it is worth learning a little about how they operate, so that you can better understand what they do, what they can do and how they do it. This is practical knowledge for when it comes to deciding which system to choose, because not all GPS systems are the same and some present more functions than others.
All car GPS navigation systems use satellites to help them determine their position. (This is not always the case with boats, because some water ways use land-based tracking stations).
The GPS is like a radio receiver, so it picks up signals from overhead satellites and interprets that data in order to determine where it is. In order to do this job properly, it needs the signals from three satellites.
This is called triangulation and is very accurate, frequently to within a metre or a yard. However, in order to ensure even more accuracy, the data from a fourth satellite is used as a check. There is very little scope for error if four satellites are being employed for pin-pointing a location.
A GPS device will tell you which way to go and if you go off route, it will advise you the best manner for getting back to the right road. However it will also do more than that. Before you begin out on your journey from A to B, you have to type in those two locations.
The GPS will then ask you whether you want to go by the quickest route, the most scenic route or whether you want to avoid motorways altogether.
This is a immense role, but it can do more than that too. If you type in the name of a restaurant along the fashion or a monument you would like to see, it will steer you from A to B via your position of interest.
One last item, be certain that the system that you purchase is upgradeable. Some are upgraded automatically, but you have to pay a monthly or annual fee. Others will sell you an upgrade which you have to install yourself. If you are at ease with making your own upgrades, all well and good, but just be aware that systematically upgrading the software is vital.
