GPS Tracking Device: GPS Car Navigation System Reviews

The Global Positioning System (GPS) is a satellite-based navigation system which makes it possible to obtain the exact position of a GPS-enabled device by using the triangulation method. The technology uses the 24 satellites placed in the orbit, which are programmed to work in any part of the world, twenty four hours a day. The position of the user is displayed on an electronic map after analyzing the time and distance measurement. This system was initially developed by the United States defense for military use, and eventually made available for civilian use in the 1980s.

The GPS tracking devices uses the Global Positioning System to ascertain the exact location of GPS equipment such as GPS-enabled cell phones and GPS-integrated car navigation systems. It records the position of the particular asset, and stores it within the tracking unit or transmits it to the Internet and other database, which eventually displays the position on a map either in real time or later. Today, one of the most common use of GPS is done in car navigation systems.

A GPS-integrated car navigation system is one of the most useful gadgets for the driver of a vehicle. It helps the driver to locate his position, while guiding him to his destination. Most of these GPS devices come with a mounting bracket and a suction cup which can help the device to stick to the windshield or dashboard. One has to be careful while mounting it on the windshield though, as it is prohibited in many administrations in the United States. The screen of the GPS integrated navigation system ranges between 3.5 to 7 inches. Having large screen devices is no doubt advantageous, as this will mean more space for map display and ample room for virtual keyboard. Even though small, a device featuring a well-designed map and clearly audible directions can work wonders for the driver, and more importantly they are relatively inexpensive.

Owing to the accuracy of Global Positioning System, with tracking range down to 1 meter, the devices used in vehicle navigation systems include a detailed map of the country, which even include streets and their names. When going to a foreign country, one can install additional maps pertaining to that region. The map is most often displayed in 3D format, which provides a graphical picture of area from an elevation of a couple of meters. As the car travels, the map on the screen of the GPS device is continuously updated, thus making it easier to be interpreted. These advanced devices also provide turn-by-turn directions, visually as well as in form of spoken instructions. The text-to-speech function in modern day GPS devices pronounce the name of the street for you as you approach them. Sometimes, the GPS device mounted in front of the driver is more distracting than the cell phone. In such a case, text-to-speech proves to be an extremely helpful function.

Most of the GPS devices used in car navigation systems today are capable of real-time tracking. These devices use wireless data signals or FM transmissions to track the receivers in real time. Some devices also sport a built-in GPS receiver which proves to be advantageous in real time tracking facility. Such a facility can help the driver to understand the traffic situation, and give an option of a different route to avoid chaotic traffic. Other important features of a GPS-enabled car navigation system include accuracy, usability, power supply, blue tooth, FM transmitter and Internet connectivity. A GPS device loaded with all these features can prove to be an ideal gadget for your vehicle.

Global Positioning System has developed considerably over a period of time, and so has the GPS based car navigation system. Manufacturers are continuously trying to offer new features so that they can be ahead in the tough race. This competitive race has eventually benefited the consumer, as more and more advanced GPS features are available at an inexpensive rate.
