Contemporary auto navigation units are really fantastic. Have you ever considered 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 called. will probably not realize quite how much knowledge they provide. It is no longer just a device to prevent you from getting lost whilst you are travelling from A to B.
Far from it. Modern GPS systems will tell you when you are passing monuments, sites of historical importance or beauty, churches, hotels, restaurants, pubs, garages, petrol stations, airports and practically anything else that you want it to inform you about. They have moved on from being only an on screen map to being a tour guide and much more..
If you are thinking of getting a GPS auto navigation system, it is worth learning a bit about how they operate, so that you can better understand what they do, what they are capable of doing and how they do it. This is useful knowledge for when it comes to choosing which system to decide on, because not all GPS systems are the same and some present more features than others.
All car GPS navigation systems use satellites to help them work out 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 processes that data in order to determine where it is. In order to do this job in the right way, it requires the signals from three satellites.
This is known as triangulation and is very accurate, frequently to within a metre or a yard. However, in order to make certain of even more accuracy, the data from a fourth satellite is used as a check. There is very little margin for error if four satellites are being used for pin-pointing a position.
A GPS item 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 road, the most scenic route or whether you would like to avoid motorways altogether.
This is a great role, but it can do more than that too. If you sort in the name of a restaurant along the way or a monument you would like to see, it will steer you from A to B via your place 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.
