We are living in a world that is technologically advanced and this has allowed every area in life to begin utilizing some of these advancements. One of the fields that have not been left behind in the usage of technology is travel. GPS is an acronym for Global Positioning System, a navigation that is satellite-based and that consists of GPS twenty four satellites that have been placed in the orbit by the United States Department of Defense. The satellites encircle the earth two times in a day in a specific orbit and at the same time transmitting signal information to the earth. The receivers of the GPS receive the information and utilize it to calculate the exact location of the user. The receiver will compare the exact time when the signal was transmitted and when the signal was received. The difference in time informs the GPS receiver the location of the satellite. This distance plus that of the other satellites enable the receiver to determine where exactly the user is this being displayed on an electronic map.
GPS has become a darling of many travelers as it assists them to drive even to unfamiliar locations without the need of stopping and asking for direction. Though the driver may be familiar with the place he or she is driving through, GPS is still utilized to calculate the time and the distance that is remaining before one reaches his or her destination. This is helpful as it may assist the driver to make out whether the gas that is in the tank will be enough to complete the journey or filling it will necessary.
Different companies have gotten involved in the production of GPS receivers (pocket sized). Some of these receivers include NL740 manufactured by LG, NUVI 680 produced by Garmin and finally Maestro 4050 made by Magellan. There are some models that have installed traffic data service and for those without, one can utilize a smart phone that runs Google maps which provide identical information. If a driver has options such as Bluetooth, the built-in systems can be utilized to silence the stereo without any human intervention whenever one gets a call.
Using GPS in a trip is very advantageous as one can easily find the place that he or she is looking for and thus save time, money and any form of embarrassment as he or she tries to locate a place. Whenever one needs to find directions to hotels or gas stations, he or she just needs to type the name on the GPS and will be given the exact location. When one maps in an address and follows the route, the GPS will tick off the distance and time to the place without any vagueness.
To avoid any road accident occurrence while the driver is checking the GPS, a voice from the GPS will keep on issuing instructions whenever one types in the name of the location. Sometimes however, the GPS technology may fail thus the information that it offers is not always infallible. It may give directions that are not correct and if one is not so sure, he or she should use other sources of information.
