The Global Positioning System (GPS) is the fully functional Global Navigational Satellite System which will help in determining the location, speed/direction and time with the assistance of 24 medium earth orbit satellites. Known as a useful tool for mapmaking, land surveying, commerce, and scientific uses, GPS is now a widely used navigation aid world wide. It is also used for various applications including study of earth.
The current GPS is divided into three major segments called space segment (SS), control segment (CS), and user segment (US).It is the navigation message broadcasted by GPS satellites that provides the time-of-day, GPS week number and satellite health information.
The history of GPS traces back to the early 1940’s when the World War II was on full swing. But it was the launching of Sputnik in 1957 by Soviet Union that paved for later developments in this field. A team of U.S. scientists under Dr. Richard B. Kershner were involved in research to monitor the movements of the satellite Sputnik, which later resulted in the technological development of GPS.
There are chances of the speed of GPS getting affected by the inconsistencies of atmospheric conditions. But this can be improved with the correction of these errors.
In the advanced modern world, GPS is mainly used in various daily life equipments including mobile phones. These devices help in making mobile phones more sophisticated and technologically advanced. With the mobile phones connected with GPS, the user will find it no hard to understand the location, climatic conditions and other geographical details.
Nowadays, GPS devices are connected with cars, helping the drivers in getting the exact knowledge of the geography, climate and details ensuring safe driving at strange areas.

GPS Auto Navigation System Safety
October 2nd, 2009
If you have installed a GPS auto navigation system in your car, then you should follow a few simple rules when driving in order to maximize your safety on the road. It doesn’t matter whether you are a long distance driver using the GPS auto navigation system
to plan the most efficient route possible, or just using your satellite navigation system to find a route around the traffic problems in your home town, the rules for using GPS systems safely are the same.
The first thing to check before you set off on your journey is to make sure that the GPS receiver is firmly mounted. If you have a windshield mounted receiver that uses a suction cup to hold it in place, make sure that it is firmly attached, while if your GPS receiver is mounted on the dash, check it to ensure that it is not going to fall off.
There is nothing worse than the unit falling off its mounting while you are driving, and this is a very dangerous thing to happen, especially if you start to reach around and try to reattach it while you are driving. If your system is removable, you should take it out of the car whenever you leave it parked in order to remove any temptation for thieves who might otherwise try and steal it off you.
Once you have started on your journey, and set the SatNav system up to plan your route, you should not touch it again. The SatNav should be there to assist you, not to distract you. Ideally, it will give you information about directions through the car’s audio system, and you will not need to look at the screen too often when you are driving, as this means that your attention will be diverted away from where it should be – the road.
It is important to remember that the advice given by a GPS auto navigation system is not infallible, and it is not a substitute for common sense. If you feel that you are being misdirected, and the route that you are following is wrong, do not be afraid of ignoring the advice and following an alternative route.
When used properly, and safely, an GPS auto navigation system
can provide you with all the information that you need in order to get to your destinations quickly and easily, with a minimum of fuss, and managing to avoid any traffic problems.
By behaving sensibly with your GPS auto navigation system – making sure it is well fitted, leaving it alone when you are driving, and paying attention when you need to – you will have a safer, quicker and more enjoyable journey than ever before, and never need get lost again.
