The GPS tracking system is one of the greatest inventions of mankind. The GPS receiver unit is the heart of the system and is used to collect the data information that is needed to give you global positioning. The start of the GPS system is the satellites that are tracking above us. By using this information from the satellites the GPS receiver device will calculate a multiple series of several different calculations of longitude and latitude that will determine the global positioning of the GPS receiver. A plot screen on the GPS unit will mark your location on a larger map that will also show you multiple points around the area for site reference. This type of technology will benefit people in so many ways including outside camping and hiking enthusiasts. The GPS receiver is a global navigational GPS system that can fit in the palm of your hand or installed in your car as a stationary unit. The GPS unit interfaces with the government's network of roaming satellites and can easily tell you where you are. The GPS receiver usually will produce a map on the screen that will include landmarks, roads and other points that you can use for all your tracking references. This GPS system is enormously beneficial for people that travel. A big benefit is the ability to navigate through unfamiliar territory and not lose your bearings. Another benefit is for travelers that use multiple vehicles especially if you're renting the vehicles you will still be able to access the GPS tracking system and navigational information to allow you to find your destination.

How does a GPS receiver get updates for mapping?

When you choose a GPS receiver device you should keep in mind that there are various different ways that you can update the GPS device. Your car's built-in GPS vehicle tracking system is updated using CDs, found at GPS stores with map data. Most portable GPS receiving units or any that are attached to a PDA will use a PC to do your updates. These units also need maps but are usually less expensive than the branded dedicated ones. When you are buying a new GPS receiver make sure you ask about the availability of the GPS software and mapping updates and how easy they are to get a hold of. Remember road networks are always changing and the maintenance of the software can be updated and can be costly sometimes. Some of the manufactures of GPS systems will base their maps around a mapsource system, which allows you to upload your own maps from scanning real ones, which will give you the most for your GPS receiver. One of the best things is there is no service fee for you to use a GPS device for your tracking.

What is a lifespan of batteries?

Battery power will last depending on how you use it, all devices use power differently. A few factors would depend on the type of battery that you are using and what current settings that you are using on the GPS receiver. Lithium batteries that are rechargeable can last you anywhere from 7-14 hours hours. Regular alkaline or fully charged NiMh batteries will give you about 9- 20 hours of life.

Ideas on how you can save battery life

Keep GPS receiver in a battery save mode

Turn off any unnecessary accessories like beeps or any back lights.

Your GPS unit should be set for the right type of battery that you are using.

By turning off the internal compass until you actually need to use it will save you an abundance amount of energy.

GPS receivers antennas are a very important part of the unit

How your GPS system functions and performs its duties is only as good as how much data information the GPS unit will receive. GPS antennas are built to give you performance from one of the most demanding environments such as hiking or in dense forests, tall buildings, canyon walls or anything that may hinder with your signal. The GPS antenna will make sure that you get the most of the signal to your GPS receiver. Another way to make the signal stronger is by the use of the active GPS antenna, which uses a low noise amplifier and we'll give you a tremendous amount of extra strength when receiving than a regular coax cable can give you. The active antenna uses power from the GPS unit for to operate.
