NavigationProcess of monitoring and controlling the movement of a craft or vehicleMap reading with a paper trail mapNavigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another. The field of navigation includes four general categories: land navigation, marine navigation, aeronautic navigation, and space navigation.
RadarRadar is a system that uses radio waves to determine the distance (ranging), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations and terrain. The term RADAR was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging".
GeopositioningGeopositioning is the process of determining or estimating the geographic position of an object or a person. Geopositioning yields a set of geographic coordinates (such as latitude and longitude) in a given map datum. Geographic positions may also be expressed indirectly, as a distance in linear referencing or as a bearing and range from a known landmark.
Corner reflectorA corner reflector is a retroreflector consisting of three mutually perpendicular, intersecting flat reflective surfaces. It reverses the direction of an incoming wave by translation via reflections from the three orthogonal sides. The three intersecting surfaces often are triangles (forming a tetrahedron) or may have square shapes. Radar corner reflectors made of metal are used to reflect radio waves from radar sets.
Frame grabberA frame grabber is an electronic device that captures (i.e., "grabs") individual, digital still frames from an analog video signal or a digital video stream. It is usually employed as a component of a computer vision system, in which video frames are captured in digital form and then displayed, stored, transmitted, analyzed, or combinations of these. Historically, frame grabber expansion cards were the predominant way to interface cameras to PCs.*As an Amazon Associate I earn from qualifying purchases.
