How Etak Built a Car Navigation System In 1985

harrymcc writes: Thirty years ago, a startup called Etak released the Navigator, an in-car navigation system. It provided turn-by-turn driving directions despite the fact that GPS did not exist, and stored its maps--which Etak had to create itself--on cassette tapes. And some of its data and technologies are still in use in today's navigation apps. Over at Fast Company, Benj Edwards tells this amazing story. I remember reading about (and lusting over) this system back then, in the much-missed DAK catalog.

    I was in a car about 5 years later that could keep in its lane along the US highway along the Appalachian Mountain Highway for nearly 100 miles to Washington DC. That car just happened to have a $300,000+ laser ring gyro and more electronics than the car cost but it did manage to keep the car in the lane all the way.

    Well, at least real good parking assist:

    I was in the 3rd grade in 1985 and one of the yearbook photographers had some type of self-parking or park-assist setup in his car. The car would perfectly park itself at the push of a button, even if the car was perpendicular to the parking space. I have no idea what this system called, and never saw anything like it again until park-assist started to come as factory equipment on new automobiles.

  7. Bowditch Navigation Systems by mbone · · Score: 2

    Bowditch Navigation Systems had a similar video navigation system, but for ships at sea. It included an integrated navigation system (LORAN, OMEGA and dead reckoning), and displayed the user's location by projecting microfiche cards of the usual navigation charts. Unlike the car system, this was a practical product with a number of customers. GPS integration was planned but never implemented; the company was caught up in a lawsuit against one of its main investors and collapsed in the 1986 time frame due to a lack of cash.
