GPS Navigation Systems are a lot like DVRs (better known as TiVo). People who don’t own them fail to understand why they’re such a big deal, and those who have them can’t live without them.

Today’s automobiles come with a variety of extras, from passenger side air bags to the ubiquitous car alarms. Entertainment options range from high-end speakers and CD players to multiple DVD players. The GPS navigation system, however, forms the bridge between safety and entertainment features. While they’re definitely entertaining, they can also become a must-have safety net in your travels.

GPS (Global Positioning Satellite) navigation systems can replace all the maps in your glove compartment and ensure that you arrive at your destination on time. GPS navigation systems are equipped with mapping software and can give you driving directions, show you alternate routes if you’re stuck in a traffic jam, and can help you negotiate a new city. While you’re on the road, a GPS navigation system can also guide you to the nearest gas stations, restaurants, and other points of interest.

Some GPS navigation systems are built right into a vehicle, while others are handheld devices that mount on your dashboard. Although GPS navigation systems are used by everyone from rescue workers to hikers, if you’re using one for driving, it’s helpful to select one that has voice navigation features. The GPS navigation system will tell you when you’re approaching a point where you need to, for example, turn, and then tell you to make your turn. This allows you to keep your eyes on the road, where they belong.

There are many accessories available for GPS navigation systems. You can, for example, buy software, GPS holders to mount your system to your dashboard or windshield, memory cards, cigarette lighter adapters, antennas, and Bluetooth.

When buying a GPS navigation system, you should consider such factors as screen size and whether you need a color or monochrome system. Color systems, for example, usually provide greater detail and better readability, but also use more power. GPS is sometimes included in handheld computers (PDAs), so if you’re in the market for a PDA, you may consider buying one that includes GPS.

Another factor to consider is the memory capacity of your GPS system. If you’d like more than the basic mapping software, you may want to consider buying a system that has additional memory capacity, such as space for a removable CompactFlash card. It’s a good investment to buy a navigation system that has voice prompts, so you won’t have to look at the screen while you’re driving.

For any driver travelling some distance, GPS navigation systems are essential and can save both time and money. Many people will think “I don’t need one of them, I never get lost”, nevertheless at the price that you or I could pick one of these up for these days, it’s common sense to purchase one for even the occasional drive to a new location.

The GPS systems that are available today offer a lot more than just the map info that many people assume. Since GPS systems have arrived, the technological advancements have added such benefits as locating hotels and restaurants, and notifying the driver of speed cameras nearby. Furthermore, they constantly update with a detailed map of the area, with details of nearby facilities like hospitals; which is a feature that can be highly advantageous in an emergency situation.

The majority of vehicle manufacturers are capable of providing the car buyer with a built-in GPS system. These systems are able to advise the necessary authority of the vehicle location in scenarios where the vehicles’ airbag is deployed, and also when the car has been reported by the owner as stolen.

The detail that many GPS systems can provide in terms of road maps and directions is incredible. Even when abroad, the relevant software is available for you to be able to use your GPS there. The software is regularly available via the internet for the GPS user to download instantly, and to benefit from in almost, if not all countries.

So let’s take a look at some of the most useful and “must-have” options with a GPS device:
- A good viewing screen is vital as it obviously displays all of the data that you will need to see. Make sure it will be clearly visible and easy to understand whilst driving, and all information is displayed in a simple easy-to-follow manner.
- Consider selecting a GPS product that is easy to use, so that you do not need to fiddle around with the setup whilst in the car, but instead can set up what you need in a few seconds.
- Purchase a device that has good mapping software, which will display detailed streets and information on facilities. Ensure that it can also be updated online so all information can remain current.
- A voice enabled system is highly important, as it allows the driver to find their destination without taking their eyes off the road to constantly check their position on the GPS.

For those that do not have a GPS device, you may still decline the need for such a product; however for those that own one, i’m certain that they will never again be without one. They are practical to keep in your vehicle and provide good-quality information when required. They can save you time when travelling to a location and vehicle costs such as petrol whilst doing so. Take a look around at the GPS devices available to find out more detailed information, and to browse the deals that can be found. With the range of equipment available, finding one to meet your requirements should be relatively effortless.

Man has always speculated about what lies beyond his immediate circle of knowledge. Many a journey has been taken and many a new land has been discovered all because of man’s curiosity. The uncertainties faced and risks taken in the name of adventures and travel has claimed many lives. Navigation and maps are vital to these activities.

Luckily for us, we live in an age of new and innovative ways for technology to help us and one of them is the GPS system.

Global Positioning System (GPS) is a worldwide navigation system formed from a constellation of 24 satellites and the associated ground stations. There can be more than 24 operational satellites; new ones are launched periodically to replace older satellites.

Each satellite orbits continually about the same ground track (as the earth turns beneath them) once per day, at an altitude calculated to ensure the satellite repeats the same track over all points approximately each 24 hours (actually 4 minutes earlier each day).

There are six orbital planes, equally spaced (60 degrees apart), and inclined at about fifty-five degrees with respect to the equatorial plan. The GPS system uses “man-made stars” as reference points to parse accurate positions to within meters.

The GPS system in it’s entirety is comprised of a network of satellites, signals, support personnel, ground based hardware and software, which make possible the establishment of one’s precise location on the Earth’s surface. The Global Positioning System is funded by and overseen by the U. S. Department of Defense (DOD). While there are many thousands of civil users of GPS world-wide, the system was designed for and is operated by the U. S. military.

The accuracy of location measurements using the global positioning system depends on the GPS receiver. High-end, survey-grade GPS receivers can determine locations precise to within centimeters. But even low-end, handheld consumer receivers, can be accurate to within fifteen meters. GPS receivers have been miniaturized to just a few integrated circuits and so are becoming economical and readily available.

The first commercial global positioning system units were precise for only about 100 meters because the military scrambled the signal–a program called Selective Availability. In the year 2000, the U.S. government removed Selective Availability, improving the accuracy of even basic handheld units to within fifteen meters. Today, with additional information from ground based correction services such as WAAS WAAS (Wide Area Augmentation Service) or U.S. Coast Guard differential GPS beacons, accuracy can be improved even further.
