Wie is toch deze man die al in 1986 een soort van navigatiesysteem in z'n Alfa Romeo had? 🙂

gps is ouder dan je denkt, hoor.


Automotive navigation systems represent a convergence of a number of diverse technologies many of which have been available for many years, but were too costly or inaccessible. Limitations such as batteries, display, and processing power had to be overcome before the product became commercially viable.[1]

1961: Hidetsugu Yagi designed a wireless-based navigation system. This design was still primitive and intended for military-use.

1966: General Motors Research (GMR) was working on a non-satellite-based navigation and assistance system called DAIR (Driver Aid, Information & Routing). After initial tests GM found that it was not a scalable or practical way to provide navigation assistance. Decades later, however, the concept would be reborn as OnStar (founded 1996).[2]

1973: Japan's Ministry of International Trade and Industry (MITI) and Fuji Heavy Industries sponsored CATC (Comprehensive Automobile Traffic Control), a Japanese research project on automobile navigation systems.[3]

1979: MITI established JSK (Association of Electronic Technology for Automobile Traffic and Driving) in Japan.[3]

1980: Electronic Auto Compass with new mechanism on the Toyota Crown.

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.[3]

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.[4] It was also the first with a map display.[3]

1981: Navigation computer on the Toyota Celica (NAVICOM).[5]

1983: Etak was founded. It made an early system that used map-matching to improve on dead reckoning instrumentation. Digital map information was stored on standard cassette tapes.[6]

1987: Toyota introduced the World's first CD-ROM-based navigation system on the Toyota Crown.[7]

1990: Mazda Eunos Cosmo became the first car with built-in GPS-navigation system[8]

GPS is in feite de merknaam voor het Amerikaanse satellietnavigatiesysteem, zoals het Russische GLONASS, het Europese Galileo en het Chinese Beidou.

Andere vormen van radionavigatie bestonden al in WOII waarbij een kruispeiling werd gemaakt van twee radiomasten. Dit systeem werd aan beide kanten van het front gebruikt trouwens, dus toen was het ook al niet echt nieuw, en werd nog steeds gebruikt door de Amerikanen ten tijde van Desert Storm.
