Dead reckoning using distance data from sensors
connected to the drivetrain, a gyroscope as well
as an accelerometer can be used as greater
reliability, as GPS navigation signal loss and/or
multipath can happen because of urban canyons
or tunnels.
In past statistics, automotive navigation is
dependant on the shortest path problem, within
graph theory, which examines how you can find
out the path that best meets some criteria
(shortest, least expensive, fastest, etc.) between
two points inside a large network.
History
Automotive satnav systems represent a
convergence of numerous diverse technologies a
few of which happen to be available for several
years, but were too pricey or inaccessible.
Limitations for example batteries, display, and
processing power needed to be overcome prior to
the product grew to become commercially viable
Navigation Data Standard (NDS)
The Navigation Data Standard (NDS) initiative, is
definitely an industry grouping of vehicle
manufacturers, navigation system suppliers and
map data suppliers whose objective may be the
standardization from the data format utilized in
vehicle satnav systems, in addition to allow a
roadmap update capacity. The NDS effort started
in 2004 and grew to become an authorized
association in '09.Standardization would improve
interoperability, particularly by permitting exactly
the same navigation maps for use in satnav
systems from 20 manufacturers.
Technology
The street database is really a vector map.
Street names or figures and house figures, in
addition to sights (waypoints), are encoded as
geographic coordinates. This permits users to
locate a preferred destination by home address
or as geographic coordinates.
Media
The street database might be kept in solid
condition read-only memory (ROM), optical media
(CD or DVD), solid condition flash memory,
magnetic media (hard disk drive), or perhaps a
combination. A typical plan is to possess a base
map permanently kept in ROM that may be
augmented with more information for any region
the consumer has an interest in. A ROM is
definitely programmed in the factory another
media might be preprogrammed, downloaded
from the CD or DVD using a computer or wireless
connection (bluetooth, Wi-Fi), or directly used
employing a card readers.
Real-time data
Primary article: Integration of traffic data with
satnav systems
Some systems will get and display info on traffic
jam using either TMC, RDS, or by GPRS/3G data
transmission via cell phones.
Integration along with other functions
The colour LCD screens on some automotive
satnav systems may also be used to show
television broadcasts or DVD movies.
A couple of systems integrate (or communicate)
with cell phones for hands-free speaking and SMS
messaging (i.e., using Bluetooth or Wi-Fi).
Automotive satnav systems may include private
information management for conferences, which
may be coupled with a traffic and trains and
buses information system.
Original factory equipment
Many vehicle manufacturers provide a Gps
navigation navigation device being an option
within their vehicles. Customers whose vehicles
didn't ship with Gps navigation can therefore
purchase and retrofit the initial factory-provided
Gps navigation unit. In some instances this is
often a straightforward "plug-and-play"
installation when the needed wiring harness has
already been contained in the automobile.
However, with a few manufacturers, new wiring is
needed, making cellular phone more complicated.
SMS
Creating sights in tangible-some time and
transmitting them via GSM mobile systems while
using Short Message Service (SMS) is called
Gps2sms. Some vehicles and vessels are outfitted
with hardware that has the capacity to instantly
send an SMS text whenever a particular event
happens, for example thievery, anchor drift or
breakdown. The receiving party (e.g., a tow truck)
can keep waypoint inside a computer, draw a
roadmap indicating the place, or view it within an
automotive navigation system.
