Great-circle navigation or orthodromic navigation (related to orthodromic course; from Ancient Greek ορθός (orthós) 'right angle', and δρόμος (drómos) 'path') is the practice of navigating a vessel (a ship or aircraft) along a great circle. Such routes yield the shortest distance between two points on the globe.
7 kwi 2020 · Many mariners and students struggle to determine the Final (and Initial) course angle of a great circle course between two geographical positions. This video...
Initial and Final Courses of a Great Circle . The initial course always has same name as the initial latitude and east or west direction of the course. The final course always has the opposite name from final latitude unless initial position and final position are in different hemispheres, when the final will have same
27 lis 2013 · In this paper, the COFI method has been developed to calculate the waypoints along the GCT successfully using the multiple products of the vector algebra (VA-MP). Due to fixing the initial great circle course, the GCT can be determined and the waypoints along the GCT can be calculated directly.
Calculates the distance between two points of the Earth specified geodesic (geographical) coordinates along the shortest path - the great circle (orthodrome). Calculates the initial and final course angles and azimuth at intermediate points between the two given.
2 lut 2021 · Brief Exposition and worked example of a great circle initial and final course calculation, utilising the distance from the first GC distance video.
24 maj 2023 · In this video we solve the problem below. Determine the great circle distance and initial course from LAT 35° 17.6' N, LONG 144° 23.0' E to LAT 47° 36.0' N, LONG 124° 22.0' W. US Coast...
