GPS (Global Positioning System) receivers not only provide the location of vehicles say with fleet management tracking if you have delivery trucks or taxi cabs or maybe you want to keep an eye on the driving habits of your teenager, these receivers also provide other valuable and important information. Such information includes the time, location, speed, direction of travel, stored locations and the ability of course to cumulate all of this data to use it over the long term.
Now a little more detail on each type of information received by the GPS receivers. With respect to time, a GPS receiver receives time information from atomic clocks, so it is much more accurate than your average bedside clock for example.
A GPS unit provides your location in three dimensions which are latitude (x coordinate), longitude (y coordinate) and elevation. The vertical (elevation) accuracy of consumer GPS receivers is not usually that great. It is usually accurate down to 15 meters or 49 feet, 95% of the time. Some GPS units are fitted with more accurate barometric altimeters for better elevation information. Also the location can usually be displayed in a number of coordinate systems such as latitude/longitude and UTM (Universal Transverse Mercator).
With speed, this is basically how fast the vehicle is travelling and paired with this is the direction that the vehicle or person is traveling towards. Note however that if you are stationary, the GPS unit cannot use satellite signals to determine which direction you are facing but instead would use an internal electronic compass to provide this information.
Stored locations are exactly as the phrase suggests which is the ability to save on the GPS receiver the locations which you were at previously or want to go to in the future. These location positions are called waypoints and a collection of these waypoints which is used to plot a course is called a route. Finally is the great use and benefits of cumulative data. Cumulative data can generally be summed up as collecting information on total distance traveled, average speed, maximum speed, minimum speed, elapsed time and estimated arrival time for a particular location.
To take a quick detour and with reference to the site SecureWithGPS, the use of this accumulated data can be very resourceful for both families and businesses alike. Say for example you are a business owner with a fleet of trucks, owner of taxis or cabs or even just a concerned parent looking out for their teenagers, the wealth of information provided by this system is phenomenal. If you have your fleet of trucks, you can track the distance covered by each truck driver when you want from the comfort of your computer. No need to go to each GPS physically and obtain the data you need, it is instead all available in one simple to use interface. This is known as fleet management and further information can be found at SecureWithGPS . You can also erect a virtual fence or boundary so that when your truck drivers deviate outside of this virtual boundary you can be notified. How is this helpful you may ask? Well, very simply, it helps to reduce the use of business vehicles for personal use by your employees and as a result should reduce fuel costs for your fleet of vehicles. For the concerned parents out there, you can more easily keep track of where your children are saying that they went on that last trip versus where they actually went. Did they go to the mall or to the library and study? Did they go to a house of a friend or to the ex-boyfriend or ex-girlfriend who was causing trouble for your family?
Finally there are many other features available on GPS (Global Positioning System) units which will be discussed in another article. To mention some of these features now however are the type of displays whether monochrome, color or no screen at all also alarms, built-in maps, electronic compass, altimeters, internal memory and of course storage systems for all of this data.
