Navigation system

• 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

  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
• Surgical navigation system, a system that determines the position of surgical instruments in relation to patient images such as CT or MRI scans.
• Inertial guidance system, a system which continuously determines the position, orientation, and velocity of a moving object without the need for external reference
• Robotic mapping, the methods and equipment by which an autonomous robot is able to construct a map or floor plan and to localize itself within it
• XNAV for deep space navigation
