What is it and how does it work? – For the uninitiated, GPS stands for Global Positioning System. It is a method of finding a receiver anywhere on earth or in space, and is probably one of the most important inventions of the 20th Century. GPS can be continuously improved and developed in order to profit in many ways, the new technologies. Well, why GPS is so important and useful? First, we must understand how it works.
To work, a network of satellites orbiting the earth is used. These satellites each broadcast a specific signal received by the antennas low cost GPS devices, where it is decrypted and used to go through a special software. The information and knowledge of these signals, the GPS software on the satellite, its special position, and took the exact calculation of time for the signal from satellite receiver to identify the trip. Using different signals from different satellites, the GPS software is now analyzing the position of the receiver, in the form of longitude and latitude.
Mapping It Out – The information on beneficiaries will be able, without something to compare it with useless. Here, the assignment is very convenient with this, GPS can analyze our situation and plan itineraries. In fact, the mapping data, which a GPS device cost. This should be updated regularly and frequently to be exact.
Several types of maps are created for different users. road users have cards with specific data on roads in their respective regions, but they do not need data on the configuration of the earth. Hikers, however, may require a detailed map of the local terrain, water marks, and tracks or roads, but they do not have much information about the road network. On the other hand, the sailors have data on the seabed, inland waterways, and other related information that allow them to navigate safely.
And the fishermen? They also use marine GPS to follow to keep the fish movements in real time and predict where they will attend the next day. In fact, the fishing cooperative has become much easier with GPS, so that ships with each other relay sites while looking for the best fishing spots. There are also GPS devices as “fish-finder, GPS and sonar capabilities to track and store combines sea fishing and detailed information.
Start with GPS – The consumer can by several GPS devices that are specifically designed for a variety of uses and functions designed in vain. In-car systems have advanced features like voice guidance, dynamic route calculation, and even update your maps from a CD-ROM. Rugged portable GPS, Garmin and Magellan as have a card in and are generally used for outdoor activities. You do not have detailed information of the road and the user has his own way from point A to point B without calculating the route.
Recently, PDAs and even some sophisticated mobile technology in their own GPS systems. A GPS receiver can easily these devices, making them potentially attached, cheaper and easier to use GPS receivers on the market today. Bluetooth technology has also begun to use GPS, PDA with one device wirelessly connected to multiple recipients.
