A navigation system is a computing system that aids in navigation. Navigation systems may be entirely on board the vehicle or vessel that the system is controlling (for example, on the ship's bridge) or located elsewhere, making use of radio or other signal transmission to control the vehicle or vessel. In some cases, a combination of these methods is used.
Navigation systems may be capable of one or more of:
- containing maps, which may be displayed in human-readable format via text or in a graphical format
- determining a vehicle or vessel's location via sensors, maps, or information from external sources
- providing suggested directions to a human in charge of a vehicle or vessel via text or speech
- providing directions directly to an autonomous vehicle such as a robotic probe or guided missile
- providing information on nearby vehicles or vessels, or other hazards or obstacles
- providing information on traffic conditions and suggesting alternative directions[citation needed]
- simultaneous localization and mapping[1]
- acoustic positioning for underwater navigation[2]
The first in-car navigation system available to consumers in 1985 was called Etak Navigation.[3] The company, Etak, was led by engineer Stan Honey and incubated by Nolan Bushnell's Catalyst Technologies in Silicon Valley.[4] Etak held a number of patents and produced digitized maps for the navigation system.[3] The maps were streamed to the navigation system from special tape cassettes. The early digitized maps turned out to be more valuable than the navigation system.[4] The car icon used in Etak Navigation display was a vector-based graphic based on Atari, Inc.'s Asteroids spaceship.[4]
