GPS Navigation System
GPS stands for Global Positioning System which uses satellites from space to provide real-time information about location and other data. Meanwhile the GPS navigation system refers to the use of this technology by a device that receives GPS signals with the purpose of determining the present location and guiding to an intended one. While GPS navigation system devices can be purchased as standalone devices, many vehicles nowadays offer them as an accessory because of their great utility when travelling.
Basically what a GPS navigation system does is that it acquires signals from the satellites to obtain the current location of the receiver in latitude and longitude. Then the device uses this data to plot your location in a map. By the time it acquires a stable signal and reading from the satellites, it will also display your direction as well as the speed that you are moving. Then, once you have input your intended an location in the device, the GPS navigation system will calculate your estimated time of arrival on that location based on your rate of movement.
Another advantage of a GPS navigation system is that it acts as your hi-tech all-in-one compass, map, and navigator. With this device, you can go to places that you have never been through without having to worry about being lost along the way. The GPS navigation system will provide instructions on how you can go to that location. Most vehicular units even come with voice instructions so you don’t even have to stop your driving just to obtain the directions. If by any chance you become lost while driving in an unfamiliar place, you can also trace back your steps with this device as it records your previous locations.
A GPS navigation system is also useful to have if you enjoy road trips. You can update the software of your device to include the latest points of interest (POI) in its maps. POI’s are relevant establishments that are worthy of knowing such as attraction spots, banks, gasoline stations, motels and the likes. With a GPS navigation system in your vehicle, you are sure that you will literally never get lost again.
