Different Types Of Gps And Their Features

If you have ever experienced the frustration of getting lost or struggling with a

paper map to find your way across a new town; you will truly appreciate the benefits of a global positioning system. These little devices are not only handy but also give you the sense of security that comes with knowing exactly where you are. However, buying GPS systems is a whole different story, given the different types of GPS and the variety if models available in the market. So, here is a look at the various types of GPS and what you can expect from them.

After-Market Vehicle GPS: The Sat Navigation units that are commonly seen in vehicles to guide drivers to their destination are available in easy to install plug and play forms. Some of these systems are so accurate that you can get turn by turn directions. The unit usually features a big color screen where maps are displayed, so that you can accurately gauge your position in reference to your destination.

These units are among the most common types of GPS and are seen in private cars as well as cabs. They are loaded with an assortment of features and are capable of giving you information on the mileage, the nearest gas station and the estimated time it will take to reach your destination. You can also buy units that lead you to the nearest convenience store or restaurant; then, there is the add-on traffic feature that can keep you away from traffic bottle necks.

When buying such a unit, you should look for Bluetooth compatibility, voice activated directions and directions with street names in addition to the features mentioned above.

Handheld GPS: This is among the most convenient types of GPS units; ideal for outdoor enthusiasts, the units is small enough to be comfortably carried wherever you go. Imagine hiking or trekking with wanton freedom because you will always be able to find your way back to the camping ground, without marking the trees. That is the kind of luxury afforded by handheld GPS units.

The more advanced GPS systems in the category can simply be slapped on to the wrist like a watch but they will be able to offer information on the altitude, points of interest along the way, routing, maps and they also have a digital compass. Some of them also have an additional feature where you can download geocache coordinates to the unit through the computer.

Handheld GPS units are perfect to ensure the safety of your family and yourself when exploring the great outdoors.

Mobile Phone Units: These are fairly common as most mobile phones have GPS tracking which comes into play when a 911 call is dialed using a cell phone. On the other hand, phones designed by Motorola can also be tracked by other users; this feature is particularly useful to track lost hikers, skiers etc. Some phone manufactures and cellular service providers also offer GPS Navigation on their phones.

The technology used in these devices is similar to the one incorporated in Street Nav Systems; however, you will be completely dependent on the cell phone towers for directions. This means that if you are out of range, your smart phone GPS will be worthless to you. Another problem with phones that features GPS is the monthly fee associated with the service. Although, you do not have to buy a separate GPS unit, the monthly fee can be an encumbrance. Also, the units themselves are no match to handheld GPS; they usually have small screens and inferior quality speakers

So, if you are all set to buy a GPS unit for yourself; this guide on the different types of GPS should help you to choose a unit that suits your requirements.
