Another early inertial navigation system for cars was the Etak Navigator, which was originally released in 1985. The idea for the device was conceived onboard Nolan Bushnell's racing yacht in a conversation between Nolan and his navigator, Stan Honey. Stan, who was also an accomplished engineer, went on to found Etak with Nolan's financial backing. You can see the device in Chevy Chase's car early on in the 1991 film Nothing But Trouble.

- yborg 4y agoWorked on early auto navigation systems at Motorola in the early-90s, using differential wheel sensor data from the ABS system for dead-reckoning interpolation between fixes from the original SA-active GPS before the full constellation was deployed. This was a hard problem to solve with the technology of that era, and impossible at an economically viable price point. Our map database was on an original Red Book single-speed CD qualified for automotive temperature range. It took minutes to plan a route. Sometimes the technology just isn't ready.
