ADVANTAGES OF A GPS SYSTEM
GPS means: Global Positioning System, and the GPS system constitutes a group of 27 satellites that orbit the Earth, and of these, 24 are active satellites, whereas the remaining 3 are back up satellites. If you are wondering Where to buy GPS Systems, buyagpssystem.com is an excellent source.The GPS system was first conceived by the U.S. Department of Defense and was first invented to assist the operations of the United States Air Force.
The principles of Triangulation are what the GPS system is based on, with the 24 active satellites relaying signals to the earth’s surface, which are then triangulated by a device known as a GPS receiver, and, depending on these signals, a person can pinpoint their exact location on the Earth.To pinpoint a specific location, your GPS receiver should be able to pick up a minimum of 3 signals from 3 different satellites, with these signals being used to calculate the distance of each satellite from the other, as well as the distance of each satellite from the GPS receiver (in other words, you), resulting in these distances being calculated, and your exact location determined.
To Start:
First of all when we talk GPS, you have to realize that there are different types of GPS systems for different purposes, like: Auto, Handheld and Marine are 3 types.
Car GPS Systems:
A Car GPS System is meant for navigational use while driving, and it will typically feature a big display screen so that can be read without taking your eyes off the road for long.Many of the newer vehicles can come with built-in car GPS systems, thus doing away with the need to buy another car GPS device.Car GPS systems have a street mapping feature, which offers you directions to your intended destination, and usually the basic car system can be obtained for about $200-$250.
Handheld GPS Systems:
A handheld system is a small and compact GPS device that typically fits in the palm of your hand, and are made such so that they are easy and convenient to carry when on foot, bike riding, camping, hiking, hunting, fishing, etc.Handheld GPS units fall into two broad categories: Mapping and Non-mapping, meaning: non-mapping GPS system typically shows your location, the time, compass heading, height from sea level, the strength of signal and the position of different satellites, and a mapping handheld GPS system will also display maps in addition to the other features, with both basic handheld GPS units running about $100-$150.
Marine GPS Systems:
Marine GPS systems are designed to be used on boats and other sea vessels, with the purpose of helping you to determine your exact co-ordinates so that you don’t get lost at sea while boating, deep sea fishing, fleet tracking, and various other marine applications.Unlike many other types of GPS systems, a marine GPS unit is typically weatherproof. These GPS units also feature marine mapping and some back tracking abilities, along with another feature that is exclusive to marine GPS systems, and that is active sonar.You should expect to pay over $250 to much higher, for a basic marine GPS system.
How To Choose A GPS System That Is Right For You:
You will either be using your GPS device while on foot, or you will be installing it someplace such as your car, boat, mountain bike, etc., so if you are going to use your GPS system while fishing, hiking, trekking, hunting etc, then the main criteria to look out for is the weight of the device and whether or not it is weather-proof, and if you choose a GPS system that is too heavy and bulky, you will not be able to carry it, thus making it useless.And as you are likely to experience ill weather, buying a weather proof GPS system is an absolute must, and another feature is the Wide Area Augmentation System (WAAS). where your handheld GPS device will be able to pinpoint your location to within 10 feet of where you are standing, which can sometimes be critical if you happen to get separated from the rest of your party.

Pocket Pc Gps
A personal digital assistant or PDA is a smart combination between a GPS device and a Microsoft software created for PDA, in the so-called PC GPS. Pocket PC systems are considered superior to Palm units in terms of functionality but a Palm is easier to use and comes with a larger range of accessories. The Bluetooth technology, the compact flash, the GPS cabling and the integrated features, all define a Pocket PC GPS in the most rewarding way possible. Let’s have a look at some of these items and see how they influence the efficiency of the combined devices.
Without an external compact memory card, the GPS unit will consume the battery power of the Pocket PC GPS and make it inoperable. Moreover, the GPS compact flash required for PDA usage could make the system a bit clumsier than you’d expect. Bluetooth technology saves a lot from the efficiency of the device, not to mention that cabling is not a problem anymore. Through a wireless system, a GPS receiver located in a backpack could be linked to a hand-held PDA. From this perspective, the Pocket PC GPS brings superior flexibility particularly since for car usage, a clear view of the sky is a must.
Since the Bluetooth technology increases the usage flexibility, its adaptation to the Pocket PC GPS solution is a bit more expensive. Even so, lots of people make the investment. The Pocket PC could also be linked to a car-powered GPS device by cables. Such GPS receivers are classified as mouse-type and they are a lot cheaper than self standing GPS units. It has another advantage too, that of saving the battery power of the Pocket PC by the possibility to be directly powered from the car batter. The main downside of this type of Pocket PC GPS is the in-car usage limitation.
For varied GPS usage you should consider a hand-held system of navigation that can be linked with the Pocket PC with a cable. This Pocket PC GPS combination proves a good idea for outdoor usage. The PDA will display the maps, but the hand-held GPS receiver can be used separately too. Having two gadgets could be annoying and uncomfortable particularly since they are wired, but unless you can afford a more sophisticated solution, you can very well do with it. Other than this handling difficulty, the Pocket PC with the included GPS device provide both good hardware options, Windows Mobile software and lots of mapping possibilities. The Pocket PC GPS unit of the future will share all these features in one unit alone.

Gps Receiver
According to the standard definition, a GPS receiver is a device that enables navigation through the satellite system, by determining the exact geographical location. The GPS receiver is in fact one of the three elements required by the Global Positioning System, and from the certain point of view, the least significant. The other two vital elements are the satellites and the control and monitoring stations. Once the GPS receiver gets the signal, it proceeds to its decoding according to latitude, longitude and altitude. Anyone can purchase a GPS receiver with the accessories necessary from commercial retailers.
To understand the importance of a GPS receiver, it suffices to say that it is crucial for air-navigation, maritime operations, military moves, emergency services, disaster relief and individual civilian use. Moreover, the GPS device allows for accurate timing for operations of mobile phones, banks and power grids. The GPS receiver is the modern way to be safe, accurate and in control of countless of activities regardless of your position on the globe. If we only consider the efficiency of streets, highways and mass transit when coordinated through GPS receiver systems, we understand the importance of this new technology worldwide.
You can reach destination on the shortest route possible or simply identify a lost vehicle: the number of features included in a GPS receiver is very high. After it reaches the receiver, the signal is decoded and processed by a special software that allows for vocal announcements and graphic displays of the routes. The vocal feature of the GPS receiver is considered very reliable and safe by lots of drivers because it is a lot easier to follow it than to periodically check the monitor for left, right or street name directions. Furthermore, the very efficiency of a trip is enhanced by the possibility to take alternate routes and avoid traffic, and all thanks to the GPS device use.
The GPS receiver technology also finds application in the constant monitoring of roads and highways by the authorities. Information on road damage, service stations, supplies, maintenance and entry or exit ramps is thus both accurate and in real time, allowing for rapid interventions if necessary. The data gathering process adjacent to the Geographic Information System (GIS) allows the formation of large databases of knowledge that is afterwards processed by lots of drivers and transportation companies that have to maximize the efficiency of the rides. There is in fact active support between the GPS and the GIS systems, and their applications are often shared.

Gps Receivers
GPS receivers are devices that get signals from orbiting satellites in order to determine the location or geographic position. There are very diverse applications of the Global Positioning System as the GPS receivers are used not only by the aviation, the marine and the military but by civilian consumers as well. The satellites spin around Earth twice a day, and their number and positioning allow for at least four to be visible at any moment you’d check the sky. The US military was intended to be the primary beneficiary, but the system and all of its applications were opened to the public after a while.
In terms of structure, you can choose between two types of GPS receivers: the stand alone GPS receivers and the items that require computer connection in order to function. The highest mobility is achieved with the stand alone devices, which perfectly matches car usage. Pre-installed software with route info, routing directions and maps is part of the built-in features of the most advanced GPS receivers. For certain regions, you can also get information on points of local attraction with the GPS devices. Garmin, Magellan, Mio, Navigon or TomTom are the companies that make the best GPS equipment available.
The devices that do not function independently require connection to a laptop, computer, PDA or smartphone. The connection of the two devices together can be established through Bluetooth technology, or with a USB or serial cable. The disadvantage with this kind of GPS receivers is that they don’t have the navigation software included, and the buyer has to get the program separately. People nevertheless buy these GPS receivers because they are cheaper, although they raise a bit of a challenge in terms of installation.
Thanks to the GPS receivers we now install on our cars, navigation is facilitated at the maximum: we no longer depend on rudimentary orientation instruments but on the most efficient technology. GPS modules will not include world maps, but that is hardly an inconvenience. The Google Maps program can be used for downloading data for a certain geographical area or country. Geo-spatial orientation will no longer be a problem when you have such a travel companion to tell you the best and fastest way to get to destination without the trouble of getting into traffic jams.

Gps Satellite
The US military forces launched the first GPS satellite in 1978. Since then, more then three dozens satellites have been launched on Earth’s orbit, servicing not only military and aviation forces but individual private users worldwide. The very existence of the Global Positioning System has in fact claimed the life of more than one GPS satellite, lost during the launch or on the orbit. Some satellites were taken out of service, others were replaced, but but no effort was spared for making GPS usage top quality. The decoding of the satellite signal is done by a GPS device or receiver that provides the exact geographical location according to three-dimensional coordinates.
Science has made such progress that GPS satellite navigation is now incorporated in the design of smartphones. The GPS seems to have become an integrated part of people’s life, but one has to wonder what will happen in a couple of years when the now orbiting satellites will have to be replaced. At present, there are management and funding issues that seem to act against the proper reconditioning of the Global Positioning System. The US Air Force maintains the entire GPS satellite structure, the economic difficulties put a lot of stress on the managers who lack funds to invest in reconditioning.
At present there are some 31 satellites in service and since only four are necessary to get a fix on the position, the average user will not feel a change if some of the orbiting devices fail to work. Sometimes information may get redundant as the same GPS receiver can get simultaneous data from six or eight satellites, which is more than necessary. In the absence of GPS satellite real-time positioning, consumers would have to start using maps all over again. The transportation systems, the maritime and military forces would suffer most if the satellites are not reconditioned.
The European states are preparing the launch of an independent satellite navigation system in 2010 that would be an alternative to the American GPS satellite applications that are now most popular. Besides the USA, other countries that have GPS satellite dominance are Russia, China and India, that operate their own Global Positioning systems. Regardless of how things are managed in terms of policy, implementation and administration at the global level, the average user will not be affected by the different modifications in the way the GPS satellite communication works. More and more people will in fact start using GPS devices for increased efficiency of navigation.
