How to Choose a GPS Receiver
The other option you can choose from is the Portable GPS Unit. Both Magellan and Garmin make Portable GPS Units. Depending on what you are looking for, you may want to go with a Garmin Portable GPS Unit such as the Garmin Portable StreetPilot C320 or a Magellan Portable GPS Unit such as the Magellan Roadmate 3050T. How GPS Works A GPS receiver uses a triangular technique to pinpoint your exact location on a map. The triangular formation uses three or four satellites at one time to send a signal to and from the GPS receiver. It does not matter whether you are using a Portable GPS Unit or a Handheld GPS Unit, you will need to be able to make contact with the satellites in order for the GPS receiver to work. Once the satellites and the GPS receiver send signals, the distance from each of the three satellites to the receiver is computed and a location is determined. Other GPS Units use palm pilots or PCs to display the location information. GPS Receivers are designed to look familiar. GPS Units sometimes include speedometers, which resemble those in cars. This makes GPS Units both appealing and easy to use, since you can mimic these applications when using them on your GPS. Choosing Based on Features The first GPS receivers were attractive to a wide variety of individuals and they all had the same or similar features. Now, GPS Receivers still cater to a wide variety of people, though rather than having to deal with every single feature you may not use in one GPS Unit, the GPS Units have been divided into brands (Magellan, Garmin, tomtom, etc.), types (portable GPS Units, handheld GPS Units, GPS PDAs, etc.) and uses (driving, hiking, etc.) You may still want a universal GPS Unit or you may want to pick out a specific GPS Unit based on why you are using your GPS. If you want a portable GPS Unit you can use for driving, you may want to consider the Garmin StreetPilot C550. If you want to use a handheld GPS Unit for hiking, you may want to consider purchasing the Magellan eXplorist 200. When picking out a GPS receiver to suit your needs consider asking both yourself and your GPS retailer the following questions: ·Are the maps accurate? ·Can you upgrade your unit if necessary?

Using
A GPS Receiver
As the Global Positioning System – or GPS – continues to rise in popularity, a host of GPS-related products continue to hit the shelves. The GPS receiver is a compact navigational system that literally fits in the palm of your hand. The GPS receiver interfaces with the government’s network of satellites and can instantly perform a series of latitudinal and longitudinal calculations that can precisely target the user’s location. The screen of the GPS receiver displays a map of the area – including roads, landmarks, and other points of reference – and the user’s location in relation to it. For outdoor hobbyists the GPS receiver has been enormously beneficial, allowing them to navigate possibly unfamiliar terrain without ever losing their bearings. Travelers who may not be using one particular car can still access satellite navigational information through the use of the GPS receiver. The GPS receiver comes in a variety of styles and is manufactured by numerous companies. It’s wise to research each GPS receiver before you make a purchasing decision. Article Source: |
