Article summary

The Etak Navigator was a revolutionary vehicle navigation system launched in 1985, which used a combination of dead reckoning, map matching, and sensors to provide location information. It was the first practical vehicle navigation system and was considered groundbreaking at the time. The system used a vector CRT display, cassette tapes for data storage, and a complex algorithm to match the vehicle's position to a digital map. The Etak Navigator was expensive, with a price tag of $1,395, equivalent to around $4,000 today.

What commenters say

  • The Etak Navigator was a remarkable achievement in navigation technology, considering the limitations of the time.
  • The use of vector displays in the Etak Navigator was a deliberate design choice due to the advantages it offered for rendering maps.
  • Polynesian navigators were skilled and able to make repeat journeys to the same destination reliably, contradicting the idea that they were simply drifting.
  • The idea that Pacific Islanders were unable to navigate from island to island is a misconception that has been disproven by evidence and oral traditions.
  • The Etak Navigator's high price made it inaccessible to many people, but it still had significant utility for those who could afford it.
  • The name 'Etak' refers to a traditional Micronesian and Polynesian navigation method that involves augmented dead reckoning.
  • The development of the Etak Navigator was a complex process that involved overcoming significant technical hurdles, including data storage and latency issues.
  • The use of rafts by Pacific Islanders was not a primary means of navigation, but rather a possible adaptation to changing circumstances.
