Source-derived summary

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

simultaneous localization and mapping

acoustic positioning for underwater navigation

The first in-car navigation system available to consumers in 1985 was called Etak Navigation. The company, Etak, was led by engineer Stan Honey and incubated by Nolan Bushnell's Catalyst Technologies in Silicon Valley. Etak held a number of patents and produced digitized maps for the navigation system. 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. The car icon used in Etak Navigation display was a vector-based graphic based on Atari, Inc.'s Asteroids spaceship.

Types of navigation systems

Automotive navigation system

Marine navigation systems using sonar

Satellite navigation system

Global Positioning System, a group of satellites and computers that can provide information on any person, vessel, or vehicle's location via a GPS receiver

GPS navigation device, a device that can receive GPS signals for the purpose of determining the device's location and possibly to suggest or give directions

GLONASS, satellite navigation system run by Russia

Galileo global navigation satellite system

IRNSS, regional satellite system run by India.

Editorial summary

Begin with the source’s own compact description: “Navigation system” is computing system that aids in navigation. The dossier treats that line as a proposition to test through Navigation, system and computing, not as a finished interpretation.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current lead gives the account dated anchors—1985—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Navigation, system and computing is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “computing system that aids in navigation” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 16, 2025. The linked authority identifier is Q3475123. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1985.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.

Three-step research path

  1. Establish the record: confirm the title “Navigation system”, its source revision and the description used here.
  2. Expand the search: follow Navigation system primary sources, Navigation system archive and Navigation research across catalogues and specialist indexes.
  3. Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.

Questions for further research

  1. Which source most directly establishes the central claim about “Navigation system”?
  2. Which observation, specimen, dataset or publication supports the account?
  3. Is the terminology current, historical or disputed?
