The Global Positioning System was created and implemented by the United States Department of Defense when it launched its first GPS satellite back in 1978. Today there are 24 satellites in the GPS network that are the cornerstone of the whole system.

There are several different types of GPS devices that are designed to take advantage of this constellation of satellites. GPS mapping devices are used to collect points and any data attached to those points for mapping purposes. In fact these devices have been used for years to collect the data that creates the maps and mapping features used by other GPS navigating systems.

Oregon 200
This is the basic model for a list price of 450 dollars. It lacks some of the features (wireless unit-to-unit transfer, digital compass, altimeter) and has only 24 MB of memory. I don't recommend this one, because the additional price of a microSD card (you're gonna need one, 24 megs isn't enough for anything) will make it cost almost as much as the next model, the Oregon 300. Also, it doesn't have some of the important features I mentioned.

The smaller versions of these navigational units are handheld devices that can be used by backpackers, hunters, and other outdoor enthusiasts. These types of GPS units will keep track of where you are, leave a breadcrumb trail of where you've been, and will guide you to where you want to go. Many of these units also feature built in cameras and voice recorders, letting you keep a record of your journeys.

The last device we'll discuss is a GPS tracking device. Much like in the movies these devices use the GPS satellite system to track objects to which they are attached. Many newer cars use these in the case they are stolen they can be quickly tracked and found. You can also find small GPS tracking units on certain cell phones, which can come in handy for the parents of teenagers You can be published without charge.
