System
Navigation SystemsThe navigation system in automobiles synchronizes with the satellite navigation
system to locate the vehicle anywhere the software will support. A navigation system
is also capable of producing directions to a location via the quickest route. The
Global Positioning System locates the user by contacting the global navigation satellite
system by utilizing a GPS receiver. The navigation system was developed by general
motors in the late 70's. The system was made available to public in the early 90's.
After Market Navigation System
In a navigation system, the current position is estimated from the position that
was determined previously. The previously determined position, along with time elapsed
speed and course are used to get an approximate position. This procedure is known
as dead reckoning. A navigation system provides many views of a map, top view and
forward view. The map which is embedded in the navigation system�s database is called
a vector map. The geographic coordinates are the street names and house numbers.
Navigation systems can allow the user to store the geographical coordinates of their
favorite point of interest. These points are known as save-points. Initial maps
are created at the manufacturer by programming a ROM, hard disk, CD, DVD or flash
memory. The navigation system can be connected to internet, CD, DVD, or computer
to download map updates.
Navigation systems also give information about traffic conditions by receiving information
from a travel message channel or TMC and displays alternate routes to avoid traffic.
TMC is a digitally coded system and delivers extremely accurate information through
radio RDS. Other miscellaneous services provided by the navigation systems are personal
information management, meeting and anniversary reminders, capturing images of the
location, speakers which can be connected through Bluetooth, video broadcasting
on the LCD screen and much more.
