Map matching
As mentioned, the GPS used by this Mobile Navigation System are susceptible to certain
errors. Their calculations may on occasion place you in a location on the map where no
road exists. In this situation, the processing system understands that vehicles travel only
on roads, and is able to correct your position by adjusting it to a nearby road. This is called
map matching.
What is GPS?
What is GPS?
The Global Positioning System (GPS) is a satellite-based
navigation system made up of a network of 24 satellites
placed into orbit by the U.S.
Department of Defense. GPS was originally intended for
military applications, but in the 1980s, the government made
the system available for civilian use.
GPS works in any weather conditions, anywhere in the world,
24 hours a day.
There are no subscription fees or setup charges to use GPS.
