A moving map display (MMD) / projected map display (PMD) is a type of navigation system output that, instead of numerically displaying the current geographical coordinates determined by the navigation unit or an heading and distance indication of a certain waypoint, displays the unit's current location at the center of a map. As the unit moves around and new coordinates are therefore determined, the map moves to keep its position at the center of the display.
Mechanical moving map displays using paper charts were first introduced in the 1950s, [1] and became common in some roles during the 1960s. Mechanically moved paper maps were replaced by projected map displays [2] [3] and digital maps during the 1970s and 80s, with resolution and detail improving along with computer imagery and the computer memory systems that held the data.
A symbol representing the location of the GPS device carried by a person or inside a vehicle, remains stationary on the display screen while a map or chart image moves beneath the symbol. [4] The display thus portrays the physical movement of the device on the displayed map or chart. The portrayal typically shows a simulated overhead view of the device location on the moving map, but some devices also simulate a three-dimensional view from the perspective of the device. Many devices also provide an option for the map or chart image to remain stationary on the display while the location symbol moves to represent physical device movement. Some moving map display systems also provide a method of displaying the elevation of the device above sea level or the earth's surface.
A common example of a moving map display today is the map display on a smart phone or tablet screen, with an app using GPS to determine the device's current position and display it on map data from the device's internal storage or from the Internet in real time. This use of phones and tablets has expanded very rapidly for navigation in car travel, hiking, and aviation. Moving map applications are now included in the base software for most phones and tablets, and include many helpful options like directions to destination, business hours, and more.
Aviation moving map apps include extensive in-flight information such as other nearby aircraft. Weather and other data is also available and may be depicted on the moving map. Some sophisticated apps, even including 3D display options for this purpose are available free, without subscription fees. [5] This trend has enabled even inexpensive aircraft with no electrical system to have very advanced Avionics in flight. Many pilots of the most expensive jets and helicopters also use such apps to supplement expensive certified avionics.
Avionics are the electronic systems used on aircraft. Avionic systems include communications, navigation, the display and management of multiple systems, and the hundreds of systems that are fitted to aircraft to perform individual functions. These can be as simple as a searchlight for a police helicopter or as complicated as the tactical system for an airborne early warning platform.
A waypoint is a point or place on a route or line of travel, a stopping point, an intermediate point, or point at which course is changed, the first use of the term tracing to 1880. In modern terms, it most often refers to coordinates which specify one's position on the globe at the end of each "leg" (stage) of an air flight or sea passage, the generation and checking of which are generally done computationally.
A head-up display, or heads-up display, also known as a HUD or head-up guidance system (HGS), is any transparent display that presents data without requiring users to look away from their usual viewpoints. The origin of the name stems from a pilot being able to view information with the head positioned "up" and looking forward, instead of angled down looking at lower instruments. A HUD also has the advantage that the pilot's eyes do not need to refocus to view the outside after looking at the optically nearer instruments.
Garmin Ltd. is an American, Swiss-domiciled multinational technology company founded in 1989 by Gary Burrell and Min Kao in Lenexa, Kansas, United States, with operational headquarters in Olathe, Kansas. Since 2010, the company is legally incorporated in Schaffhausen, Switzerland.
An automotive navigation system is part of the automobile controls or a third party add-on used to find direction in an automobile. It typically uses a satellite navigation device to get its position data which is then correlated to a position on a road. When directions are needed routing can be calculated. On the fly traffic information can be used to adjust the route.
In aviation, an electronic flight instrument system (EFIS) is a flight instrument display system in an aircraft cockpit that displays flight data electronically rather than electromechanically. An EFIS normally consists of a primary flight display (PFD), multi-function display (MFD), and an engine indicating and crew alerting system (EICAS) display. Early EFIS models used cathode ray tube (CRT) displays, but liquid crystal displays (LCD) are now more common. The complex electromechanical attitude director indicator (ADI) and horizontal situation indicator (HSI) were the first candidates for replacement by EFIS. Now, however, few flight deck instruments cannot be replaced by an electronic display.
The Garmin G1000 is an electronic flight instrument system (EFIS) typically composed of two display units, one serving as a primary flight display, and one as a multi-function display. Manufactured by Garmin Aviation, it serves as a replacement for most conventional flight instruments and avionics. Introduced in June 2004, the system has since become one of the most popular integrated glass cockpit solutions for general aviation and business aircraft.
The Yeoman Plotter was a plotter used on ships and boats to transfer GPS coordinates or RADAR echo locations onto a paper navigation chart and to read coordinates from the chart. It was manufactured from 1985 to 2014/2015 and was an intermediary step between traditional paper chart navigation and full electronic chart displays. It was easy to understand for people that were accustomed to paper charts and much cheaper than electronic chart displays available at the time. The continuing fall in prices of electronic chart displays, their increase in functionality such as radar overlay and the advent of cheap tablets eventually made the Yeoman plotter uncompetitive.
Since the Global Positioning System (GPS) was introduced in the late 1980s there have been many attempts to integrate it into a navigation-assistance system for blind and visually impaired people.
An electronic flight bag (EFB) is an electronic information management device that helps flight crews perform flight management tasks more easily and efficiently with less paper providing the reference material often found in the pilot's carry-on flight bag, including the flight-crew operating manual, navigational charts, etc. In addition, the EFB can host purpose-built software applications to automate other functions normally conducted by hand, such as take-off performance calculations. The EFB gets its name from the traditional pilot's flight bag, which is typically a heavy documents bag that pilots carry to the cockpit.
Traffic reporting is the near real-time distribution of information about road conditions such as traffic congestion, detours, and traffic collisions. The reports help drivers anticipate and avoid traffic problems. Traffic reports, especially in cities, may also report on major delays to mass transit that does not necessarily involve roads. In addition to periodic broadcast reports, traffic information can be transmitted to GPS units, smartphones, and personal computers.
Global Navigation Satellite System (GNSS) receivers, using the GPS, GLONASS, Galileo or BeiDou system, are used in many applications. The first systems were developed in the 20th century, mainly to help military personnel find their way, but location awareness soon found many civilian applications.
A Personal Navigation Assistant (PNA) also known as Personal Navigation Device or Portable Navigation Device (PND) is a portable electronic product which combines a positioning capability and navigation functions.
