Gps Automotive Systems
By Josue Ayala
There are a number of different styles of auto navigation systems available to suit the needs of the individual, from basic models through to expensive and highly accurate systems able to manage large amounts of data and provide information to the users in order to give feedback about where they have been.
The simplest kind of auto navigation system is a removable gadget that stores the map data internally, and uses a satellite signal to pinpoint the position of the unit. By combining the map data and the satellite signal, routes can be planned, and the user can find their way, while seeing a graphical representation of their route on a small screen. These auto navigation systems can be either removable, or fixed into the car. Many new models actually integrate the into the dashboard, while non fixed systems can either be mounted on the dash, or attached to the windshield using a suction cup.
As well as dedicated auto devices, it is also possible to buy a large number of other gadgets with as a built in feature. Some PDAs can have a module plugged in to them, and used in cars, and an increasing number of cell phones have as a standard feature. On the whole, although these devices have built in, it is not of the same standard as a dedicated system, and wile it may help you know where you are, it will not provide such accurate data or be able to plan routes on the go as well as one of the custom systems from Garmin or Magellan.
GPS or Global Positioning System is a fully functional Global Navigation Satellite System. This system uses an artificial constellation of 24 medium Earth orbit satellites. These satellites transmit microwave signals, thus enabling a receiver to determine its location, speed, direction and time not because you never know when there will be a detour, bad weather, a wreck, or anything .
So you want to narrow things down some more and look for a vendor that has a dedicated store on an auction site. Yes, they exist, and
some of them offer both new and refurbished systems from all of the major manufacturers. They usually carry all the accessories as well, and since they use auctions to sell, you can get some terrific deals. Further, unlike even the best websites, the inventory of auction sites constantly changes. So you not only have a shot at a terrific deal, but there is also an unusually large variety of products to choose from, both new and refurbished.
Automotive systems have the same features as many of the handheld portable receivers do, however, most of them are larger and stay in the car. But there are a few models that can be taken out of the car and carried around with you as you walk around the city or the woods; it depends on which model you want to purchase. Most of the automotive models have a larger LCD touchscreen and come with more maps than the handheld units. Street level maps and millions of POI's or points of interests such as restaurants, ATM's and banks, zoo's, schools and parks are already preprogrammed into the automotive systems. Although there are programs in which you can program your own POI's such as schools and speed cameras so you know to avoid them each time you pass by that way.
GPS technology is still new in terms of public use and access. A marine can be the lifeline for your voyage if you find yourself out in the middle of the high seas without a clue as to where you are going. It was just a few years ago that systems appeared in the marketplace and to this day, it's easier to find someone without than with one.
