in Kyoto, equipped with GPS navigation systemAn automotive navigation system is a satellite navigation system designed for use in automobiles. It typically uses GPS to acquire position data to locate the user on a road in the unit's map database. Using the road database, the unit can give directions to other locations along roads also in its database. Dead reckoning using distance data from sensors attached to the drivetrain and a Inertial guidance system#Vibrating gyros can be used for greater reliability, as GPS signal loss and/or multipath can occur due to urban canyons or tunnels.

History Alpine Electronics claims they created the first automotive navigation system in 1981.

Honda claims to have created the first navigation system starting in 1983, and culminating with general availability in the 1990 Acura Legend. This analog computer system used an accelerometer to navigate using Inertial Navigation System, as the GPS system was not yet generally available.

Both Mitsubishi Electric and Pioneer Corporation claim to be the first with a GPS-based auto navigation system, in 1990. Also in 1990, a draft patent application was filed within Digital Equipment Co. Ltd. for a multi-function device called PageLink that had real-time maps for use in a car listed as one of its functions.

Magellan, a GPS navigation system manufacturer, claims to have created the first GPS-based vehicle navigation system in the U.S. in 1995.

Technology Visualization software

Navigation systems use a combination of:

Road database Contents The road database is a Vector Map of some area of interest. Street names or numbers and house numbers are encoded as geographic coordinates so that the user can find some desired destination by street address (see map database management).

Point of interest (waypoints) will also be stored with their geographic coordinates. Point of interest specialties include Road safety camera, fuel stations, public parking, and "parked here" (or "you parked here").

Contents can be produced by the user base as their cars drive along existing streets (Wi-Fi) and communicating via the internet, yielding a free and up-to-date map.

Map Formats Formats are uniformly proprietary; there is no industry standard for satellite navigation maps.The map vendors Tele Atlas and NAVTEQ create the base map in a standard format Geographic Data Files, but each electronics manufacturer compiles it in an optimized, usually proprietary format. GDF is not a CD standard for car navigation systems. GDF is used and converted onto the CD-ROM in the internal format of the navigation system.

CARiN CARiN is a proprietary navigation map format created by VDO/Dayton that is used in a number of navigation-equipped vehicles. The CARiN pseudo-acronym stands for Car Information and Navigation.

The original system uses CD-ROM-based maps, with ISO_9660 encoding for their file system. Maps can be recognized by the presence of the following files on the CD:



Newer derivatives also use DVD-ROM-based maps for extra capacity, and add support for long file names. Older CARiN-compatible navigation computers are not able to read the newer DVD maps, but the DVD-enabled computers are still able to read the CD-based maps.

Vehicle manufacturers who have used or are still using this format in one or more of their ranges include:

After-market GPS vendors using the format include:

Older CD-based CARiN maps are completely interchangeable between manufacturers; however, differences in the more modern DVD maps are starting to change this.

Point of Interest information can be stored either in the database file itself (carindb), or in a separate database under a directory named 'TPD.' Encoding of GPS coordinates in the TPD folder is proprietary and varies between navigation computers (e.g., BMW 'HIGH' vs BMW 'Professional' editions of the navigation map). Editors are now available to customize these POI (see links below).

CARiN media is sometimes referred to colloquially as "Carinet" or "CarinDb," after the names of the files on the navigation media.

S-Dal This is a proprietary CD-ROM-based map format created by Navteq. The applications and devices using this media are not known, even although its specifications are published on the Navteq website.

Media The road database may be stored in Read-only memory, optical media (CD or DVD), solid state flash memory, magnetic media (hard disk), or a combination. A common scheme is to have a base map permanently stored in ROM that can be augmented with detailed information for a region the user is interested in. A ROM is always programmed at the factory; the other media may be preprogrammed, downloaded from a CD or DVD via a computer or wireless connection (bluetooth, Wi-Fi), or directly used utilizing a card reader.

Some navigation device makers provide free map updates for their customers. These updates areoften obtained from the vendor's website, which is accessed by connecting the navigation device to a PC.

Real-time Data Some newer systems can not only give precise driving directions, they can also receive and display information on traffic congestion map and suggest alternate routes. These may use either Traffic Message Channel, which delivers coded traffic information using radio Radio Data System, or by GPRS/3G data transmission via mobile phones.

One key type of real-time data is Traffic information, which includes:

Other real-time data includes weather broadcasting, etc.

Integration and Other Functions

Controversy Safety Features Vehicles produced by Subaru and Lexus, as well as Lexus' parent company, Toyota, lock out many of the features when the vehicle is in motion. The manufacturers claim this is a safety feature to avoid the driver's being distracted. Many users have complained that passengers are not able to enter destinations while in motion, even though it is safe to do so. Additionally, drivers have complained that it is often more dangerous to pull off a highway and stop than it would be to enter a destination into the system.

Misdirection A number of road accidents have been attributed to misdirection by satnav systems. On 11 May 2007, a driver followed satnav instructions in the dark and her car was hit by a train on a rail crossing that was not shown on the system. In Exton, Hampshire, local residents have erected signs warning drivers to ignore their satnav systems.

GPS vs Speed Camera Accuracy In July 2007, an Australian man successfully overturned a speeding conviction after evidence from a GPS navigational track proved that he did not exceed the speed limit.

Other functions

Retrofitting of GPS A vehicle can be Retrofit with a GPS unit if it did not originally have one. There are three approaches that can be taken here:

Portable GPS This type of installation is not permanently integrated into the vehicle, having only a simple bracket to mount the device on the surface of the dashboard and powered via the car cigarette lighter. This class of GPS unit does not require professional installation and can typically be used as handheld device, too.

Benefits of this type of GPS unit include low cost as well as the ability to move them easily to other vehicles. However, their portability also means they are easily stolen if left inside the vehicle. Furthermore, not having a magnetic compass and being unable to use inputs from the vehicle's Wheel speed sensor, means that they cannot use dead reckoning in tunnels where there's no GPS signal.

An portable automotive navigation system kit generally includes:



Original Factory Equipment Many vehicle manufacturers offer GPS as an option in their vehicles. Customers whose vehicles did not ship with GPS can therefore purchase and retrofit the original factory-supplied GPS unit. In some cases this can be a straightforward 'plug-and-play' installation if the required wiring harness is already present in the vehicle. However, with some manufacturers, new wiring is required, making the installation more complex.

The primary benefits of this approach are an integrated and factory-standard installation. Many original systems also contain a gyrocompass or Accelerometer, as well as accepting inputs from the vehicle's wheel speed sensor, thereby allowing them to navigate via dead reckoning when a GPS signal is temporarily unavailable. However, the costs can be considerably higher than other options. In some cases, it may even be more economical to buy a similar vehicle that already has a factory-fitted GPS.

Aftermarket A number of manufacturers supply Aftermarket (automotive) GPS units that can be integrated permanently into the vehicle. A typical location for such an installation is the DIN slot for the radio/tape/CD. However, in extreme cases, the dashboard may also be remodeled to accommodate the unit.

This approach can be considered a tradeoff between the previous two options. Benefits include a more secure and better cosmetic finish than a portable device, and lower cost compared to the installation of an original factory-supplied GPS.

Alternatives Mobile Phones with GPS Capability Commercial navigation software is widely available for most current smartphones as well as some Java (programming language)-enabled phones that allows them to use an internal or external GPS receiver (in the latter case, connecting via serial communications or Bluetooth). Phones with this capability function no differently to a dedicated portable GPS receiver and may even use the same software.

More bespoke solutions also exist for mobile phones with GPS Phone. One such example is marketed by Verizon Wireless in the United States, and is called "VZ Navigator." The system uses gpsOne technology to determine a person's location, and then uses the mobile phone's data connection to download maps and calculate navigational routes.

SMS Establishing points of interest in real-time and transmitting them via GSM cellular telephone networks using the SMS (SMS) is referred to as Gps2sms.

Some vehicles and vessels are equipped with hardware that is able to automatically send an SMS text message when a particular event happens, such as:



The receiving party (e.g., a tow truck) can store the waypoint in a computer system, draw a map indicating the location, or see it in an automotive navigation system.
