  2. GPS Exchange Format - Wikipedia

    en.wikipedia.org/wiki/GPS_Exchange_Format

    A GPX file's main components include waypoints, routes, and tracks: A waypoint (wptType) consists of the WGS 84 (GPS) coordinates of a point and possibly other descriptive information. A route (rteType) is an ordered list of routepoints (or waypoints representing a series of significant turn or stage points) leading to a destination. [3]

    ARINC 424 or ARINC 424 Navigation System Data Base Standard is an international standard file format for aircraft navigation data maintained by Airlines Electronic Engineering Committee and published by Aeronautical Radio, Inc.

  4. GeoJSON - Wikipedia

    en.wikipedia.org/wiki/GeoJSON

    GeoJSON [1] is an open standard format designed for representing simple geographical features, along with their non-spatial attributes.It is based on the JSON format.. The features include points (therefore addresses and locations), line strings (therefore streets, highways and boundaries), polygons (countries, provinces, tracts of land), and multi-part collections of these types.

  5. Restricted random waypoint model - Wikipedia

    en.wikipedia.org/wiki/Restricted_random_waypoint...

    It is important to remove the transients for performing meaningful comparisons of, for example, different mobility regimes. A standard method for avoiding such a bias is to (i) make sure the used model has a stationary regime and (ii) remove the beginning of all simulation runs in the hope that long runs converge to stationary regime.

  6. Great-circle navigation - Wikipedia

    en.wikipedia.org/wiki/Great-circle_navigation

    For example, to find the midpoint of the path, substitute σ = 1 ⁄ 2 (σ 01 + σ 02); alternatively to find the point a distance d from the starting point, take σ = σ 01 + d/R. Likewise, the vertex, the point on the great circle with greatest latitude, is found by substituting σ = + 1 ⁄ 2 π. It may be convenient to parameterize the ...

  7. Waypoint - Wikipedia

    en.wikipedia.org/wiki/Waypoint

    A notable example is the worldwide use, in orienteering sports, of waypoints with a map that omits a coordinate system, known as control points. [ 4 ] In aerial celestial navigation, waypoints are precomputed along an aircraft's great circle route to divide the flight into rhumb lines and allow celestial fixes to be more rapidly taken using the ...

  8. Area navigation - Wikipedia

    en.wikipedia.org/wiki/Area_navigation

    A simple diagram showing the main difference between traditional navigation and RNAV methods. Area navigation (RNAV, usually pronounced as / ˈ ɑːr n æ v / "ar-nav") is a method of instrument flight rules (IFR) navigation that allows an aircraft to choose any course within a network of navigation beacons, rather than navigate directly to and from the beacons.

The Digital Aeronautical Flight Information File or DAFIF (/ ˈ d eɪ f ɪ f /) is a comprehensive database of up-to-date aeronautical data, including information on airports, airways, airspaces, navigation data, and other facts relevant to flying in the entire world, managed by the National Geospatial-Intelligence Agency (NGA) of the United States.
