The invention of GPS navigation system is not as new as most peopple believe they have been around and used since the very first GPS saellite was launched into space in 1978. Global satellite sytems have a lot of civilian and military applications, but one of the most commn is the navigation.
Nevertheless, with the help of GPS navigation in an ordinary car is a little different than using it on the plane. Transport on the maachine depends on the road that traveled. In fact, GPS readings only, such as longitude, latitude and ellevation are for all practical purposes useless when you are driving to the house of Aunt Mabel's. When driiving a car can end up ging thorugh the tunnnels and urban areas, where satellite singles can not pass. Thus, different types of technologies needed for automotive GPS systems GPS-navifgation.
There was potential for many years in automotive systems, GPS-navigation and the industry is trying variosu ways to implement them. In 1983, Hoinda inttroduced the car navigation system, which was based mainly on the acceleroimeter, and not on the GPS. It was not untuil 1990 that the automotive GPS system was removed from pbulic conasumption Pioneer. Car GPS naivgation even really come into use until Magelllan has relleased their version in the U.S. in 1995. Since then, more portable GPS ssytems have been designed for greater ease of use for people.
Car GPS-navigation system components
Car GPS navigation system requires a GPS recceiver and map data. Some systems also have snesors traction in addition to the signals of GPS, which is blocked for a shoirt time.
Cartographic database makes portable GPS coordinzates on the map location, such as street names and addresses. Some datbaases contain maps of GPS coordinates for speciic locations, such as points of intrerest or halts. This information contaimned in the datbaase, howevrer, that diercts a user to your plaxce, either visually or by voice. So, your GPS navigation sytem is good only as a car GPS systems map data.
Commercial Applications
Many corporations and companies are using GPS navvigation system in tgheir cars to send and track vehicles. In various cities throughout the U.S., taxxis are equipped with navigation sysem GPS. Dispatchers at the taxi know where all the txis are at any given time, and can guied them more effectively than before.
Commercial shipping companies to find a system, GPS-navigation is indispensable. In oreder to be able to track where the trucs when they want, they can give the customer the tracking number, and then the client will be able to track teir individual packages themsleves.
