ADVANTAGES OF A GPS SYSTEM

GPS is an acronym for the Global Positioning System, and the GPS system constitutes a group of 27 satellites that orbit the Earth, with 24 being active satellites, and the remaining 3 are back up satellites.

The GPS system was the brain child of the U.S. Department of Defense.

The principles of Triangulation are what the system is based on, with the 24 active satellites relaying signals to the earth’s surface, which are then triangulated by a device known as a GPS receiver, and on the basis of these signals, a person can pinpoint their exact location on the Earth. If you are truly interested in gps systems for sale, below is a great guide for helping you with your purchase.

To Start:
First of all when you talk GPS, you must realize that there are different types of GPS systems for different purposes, like: Auto, Handheld and Marine are 3 types.

Car GPS Systems:
A Car GPS System is meant for navigational use while driving, and it will typically feature a big display screen so that it is easy to read without taking your eyes off the road for long periods of time Many of the newer vehicles can come with built-in car GPS systems, thus doing away with the need to buy another car GPS device. All car GPS systems have a street mapping feature, which offers you directions to your intended destination, and usually the basic car GPS system can be obtained for about 0-0.

Handheld GPS Systems:
A handheld GPS system is a small and compact GPS device that typically fits in the palm of your hand, and are made such so that they are easy and convenient to carry and use when on foot, bike riding, camping, hiking, hunting, fishing, etc.Handheld GPS devices fall into two broad categories: mapping and non-mapping, meaning: non-mapping GPS system will show your location, the time, compass heading, height from sea level, the strength of signal and the position of different satellites, and a mapping handheld GPS system will also display maps in addition to the other features, with both basic handheld GPS units running about 0-0.

Marine GPS Systems:
Marine GPS systems are designed to be used on boats and other sea vessels, with the purpose of helping you to determine your exact co-ordinates so that you don’t get lost at sea while boating, deep sea fishing, fleet tracking, and various other marine applications. Unlike other types of GPS systems, a marine GPS unit is typically weatherproof. These GPS units also feature marine mapping and some back tracking abilities, with another feature that is exclusive to marine GPS systems, and that is active sonar.
You will pay over 0 for a basic marine GPS system.

How To Choose A GPS System That Is Right For You:
You will either be using your GPS device while on foot, or will be installing it someplace such as your car, boat, mountain bike, etc., so if you are planning to use your GPS system while fishing, hiking, trekking, hunting etc, then the main criteria to look out for is the weight of the device and whether or not it is weather-proof, and if you choose a GPS system that is too heavy and bulky, you will not be able to carry it, thus making it useless. And, you could probably experience ill weather at some time, buying a weather proof GPS system is an absolute must, and another feature is the Wide Area Augmentation System (WAAS). where your handheld GPS device will be able to pinpoint your location to within 10 feet of where you are standing, which can sometimes be critical for adventure seekers and outdoor buffs, or if you happen to get separated from the rest of your party.
