The World's First In-Car Navigation System Looked Like Something From Fallout

By Gizmodo Australia on at

Meet the Honda Electro Gyro-cator. It's widely considered to be the world's first automotive navigation system, developed 36 years ago. And it looked like it should be on the wrist of a wasteland warrior wearing power armour.

The Electro Gyro-cator didn't use GPS, if we're splitting hairs. Its 1981 launch only closely followed the 1978 creation of the Global Positioning System, and it didn't have any kind of self-contained radio communication technology. Instead, it used a form of inertial navigation, with an internal gyroscope and odometer that tracked the direction and speed a car was travelling to constantly update its position on the (laminated, paper) map that it magnified on its cathode ray tube display.

And it came with a book of maps of the region it was sold within. This is genuinely something I'd expect to find in Fallout, not in the dashboard of an '80s Honda Legend. It's gorgeous. Honda says it, in part, "triggered the global popularisation of map-based automotive navigation systems" — I just wish they all looked this good.

The Gyro-cator was today honoured with an IEEE Milestone award from the worldwide Institute of Electrical and Electronics Engineers as a significant innovation "in the areas of electrical, electronics, information and communications technologies", an award reserved for tech over 25 years old that has contributed to the advancement of society. Here's Honda's explanation of how the Electro Gyrocator operates:

The Honda Electro Gyro-cator, commercialised in 1981, was the world’s first map-based automotive navigation system. Honda adopted a direction sensor which was developed as a result of the world’s first practical application of gas-rate gyro sensor for automobiles. The gas-rate gyro sensor detects the direction the vehicle is moving.

The combination of this direction sensor, driving distance sensor, microcomputer and other technologies enabled it to detect direction and the distance of the movement, which were used to calculate the current position of the vehicle. By indicating the current location, direction and driving trajectory of the vehicle on a cathode-ray tube (CRT) display where the user placed the map film, it was made easier for the driver to select which path to take.

And here it is in action, in all its retro-glory:
