GPS systems all started out in the army in the year 1970. In the army, many soldiers needed navigation systems to know their directions around other countries. Without this device it would be really hard for them to find their way around. This device has saved much of the soldiers time in war and has also saved them many lives. GPS systems are very powerful devices and are a great navigation system to use to get around. So what exactly are GPS systems?GPS which stands for global positioning system, according to dictionary.com is: A system of satellites, computers, and receivers that is able to determine the latitude and longitude of a receiver on Earth by calculating the time difference for signals from different satellites to reach the receiver.GPS systems have gone for beyond just serving the army. They now serve just about everyone. These navigation systems help drivers find there way through city streets and help hikers find their way through the rough terrains of the mountains. They also help pilots find their way around the skies as well as helping mariners find their way around the great sea. The GPS systems technology can help serve anyone in need of it.GPS systems are especially a great thing to have for men, and I’m sure all women would agree. As everyone knows men don’t ask for directions. If a man is just to cool to ask for directions he could simply use his navigation system and would never get lost and of course would never have to ask for directions again. This saves the time of the wife who always would have to end up asking for directions. If you really think about it, using the GPS to get directions is a form of asking for directions, but shhhh don’t tell any man this.When you decide to buy a GPS system for yourself, I would recommend any Garmin GPS. Garmin’s are the number one brand name for GPS’s and I’ve heard nothing but good things from people who have bought them. By all means do your research on all different types of GPS systems but at the end you’ll realize that no other navigation system can beat the Garmin brand.
