GPS devices are increasingly being blamed for accidents caused by heavy trucks. A reported 15,000 bridge strikes were reported in 2010. These resulted in a total of 214 deaths and 3,000 injuries. More and more truck drivers arrive at unintended destinations and are flabbergasted as to how they got there. These blunders have oftentimes resulted in some their truck being involved in a collision. Unfortunately, many truck drivers believe their GPS devices know exactly where to guide them and trust them to do just that. This is a big mistake as it is being acknowledged that many GPs devices have incorrect information for truck drivers.
Many have incorrect or outdated mapping information. Many are not designed for commercial truck drivers. They may use consumer targeted software as opposed to commercial targeted GPS software for truck drivers. As a result many of these GPS units direct truckers into areas with low weight limits, low bridge areas, residential areas or other areas where heavy trucks are not allowed to be. These accidents have caused many truck drivers injuries and deaths. They have also caused delays for shippers and receivers. Although there are other causes of truck accidents, gps errors are a major cause.
Fortunately if you’re having problems with the GPS units such as information displayed by car navigation systems, handheld personal navigation devices. wrong addresses, missing location names, low bridges, closed highway exits, etc. it’s likely you’re experiencing a mapping software issue, not a problem with the Global Positioning System (GPS). You may be able to fix this problem.
GPS Helps You Get Your Coordinates
GPS satellites are much simpler than most people think. They cannot track you. They don’t have comprehensive map databases like Google Earth. In fact, they have no knowledge of anything on the ground.
Who Provides the Maps?
The maps and other information about roads, addresses, businesses, etc., are loaded onto consumer navigation devices by the commercial companies that manufacture them. The U.S. government’s GPS program does not provide any of this data.
GPS satellites are just beacons, like lighthouses, that tell you where they are in space. They do not tell you where you are. Your navigation device uses the satellites as reference points to determine your coordinates on the Earth in terms of latitude, longitude, and altitude.
Of course, raw coordinates are useless without a map. The earliest GPS receivers did not have built-in maps, so users had to plot their coordinates on paper maps to navigate. Only in recent years has the technology existed to include digital mapping features in affordable navigation devices. Even today, many GPS units don’t come with maps — for example, tracking devices used on prisoners and animals.
Most manufacturers get their digital maps and data from commercial map makers (or digital content suppliers), the largest being NavTeq and Tele Atlas. Some device manufacturers develop their own maps.
In addition to maps, many navigation devices offer features such as route suggestions, traffic alerts, and voice announcements of turns and street names. These extras are provided by the device manufacturers and have nothing to do with the GPS satellites. Read more here:
