when was the first generation of automobile navigation systems invented?
1980
bullet::::- 1980: electronic auto compass with new mechanism on the toyota crown.









































bullet::::- 1981: the earlier research of catc leads to the first generation of automobile navigation systems from japanese companies honda, nissan and toyota. they used dead reckoning technology.









































bullet::::- 1981: honda's electro gyro-cator was the first commercially available car navigation system. it used inertial navigation systems, which tracked the distance traveled, the start point, and direction headed. it was also the first with a map display.









































bullet::::- 1981: navigation computer on the toyota celica (navicom).
automotive navigation system
integration of traffic data with navigation systems enables navigation systems to use traffic and other related data to optimise routing and travel times by taking into account traffic conditions and other disruptions to traffic flows. the integration may occur in a number of ways. for example, integrated automobile navigation systems use an on-board navigation system and cellular telephone. the navigation system would use the global positioning system (gps) to position the automobile with respect to streets in a map database, to determine a route to the destination and to update the location as the automobile moves. a cellular telephone in the automobile may then communicate with a traffic information server to obtain travel times for each street segment of the route, which would then be used to refine the planned route, or to offer to the driver as an alternative. the cellular telephone can also be used to provide dynamic travel time information to the traffic information server, with each automobile in the system periodically transferring travel times for each segment that is traversed. the traffic information server would then analyse travel times to update travel time data for each street segment, which is then available to other users when they next connect to the traffic server. other integration models exist.
