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.
There exists algorithms for perfect simulation of the general restricted random waypoint. They are described in Perfect simulation and stationarity of a class of mobility models (2005) [2] and a Python implementation is available on GitHub. [3]
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.
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.
A fly-by waypoint is a waypoint that marks the intersection of two straight paths, with the transition from one path to another being made by the aircraft using a precisely calculated turn that "flies by" but does not vertically cross the waypoint. Waypoints used in aviation are given five-letter names. [5]
Among them, the ANDIK2G Standard Instrument Departure [4] for reaching the ANDIK waypoint northeast of Amsterdam read as follows: [note 1] Lateral route: Track 222° MAG. At 500 ft AMSL turn left (turn MAX 220 KT IAS) to track 093° MAG. At PAM 223 turn left to intercept PAM 207 inbound PAM VOR to intercept PAM 016 to ANDIK (25.2 PAM).
If a navigator begins at P 1 = (φ 1,λ 1) and plans to travel the great circle to a point at point P 2 = (φ 2,λ 2) (see Fig. 1, φ is the latitude, positive northward, and λ is the longitude, positive eastward), the initial and final courses α 1 and α 2 are given by formulas for solving a spherical triangle
