The navigation radar of a ship is currently considered a primary position verification device by navigators, as the radar can be used to identify conspicuous objects or coast lines, giving range/bearing to objects of a known charted position. If a radar target - and thus the associated range / bearing of a conspicuous object - can be ...
Radar ranges and bearings can be very useful for navigation. Radar navigation is the utilization of marine and aviation radar systems for vessel and aircraft navigation.When a craft is within radar range of land or special radar aids to navigation, the navigator can take distances and angular bearings to charted objects and use these to establish arcs of position and lines of position on a ...
Using hyperbolic geometry and radionavigation principles, a position fix with an accuracy on the order of 5–10 kilometres (3.1–6.2 mi) was realizable over the entire globe at any time of the day. Omega employed hyperbolic radionavigation techniques and the chain operated in the VLF portion of the spectrum between 10 and 14 kHz .
Robin Radar Systems is a European-based defense and technology company founded in 2010. According to the company website, “Robin” is an acronym that stands for Radar Observation of Bird Intensity.
The way in which the Yeoman plotter combines speedy GPS position fixing with a paper chart is cited as a benefit for two principal reasons. The first is one of safety and reliability - even the best marine electronics fail from time to time, and if the boat's electronic instruments should cease to work then a recent pencil plot on a paper chart becomes extremely valuable.
Horizontal fixes of position from known reference points may be obtained by sight or by radar. Vertical position may be obtained by depth sounder to determine depth of the water body below a vessel or by altimeter to determine an aircraft's altitude, from which its distance above the ground can be deduced. Piloting a vessel is usually practiced ...
In an interview with NBC News on Monday, Robin Radar Systems general manager Kristian Brost said the company’s radars can detect a drone in the sky, but “we can’t tell you who’s flying it ...
Sensors information (radar, sonar, and transponder data) is provided to the track algorithm using a polar coordinate system, and this is converted to cartesian coordinate system for the track algorithm. The polar to Cartesian conversion uses navigation data for sensors mounted on vehicles, which eliminates sensor position changes caused by ship ...
