Celestial Navigation

Abstract

To carry out any activities at sea one needs to know how to fix positions, set a course and measure the distance. In the area of fisheries, navigational knowledge is obviously essential. For instance, when a fishing boat is preparing to leave a port for a fishing ground, the planned sea route (course) must be drawn on the charts, and the course in degrees and distance in nautical miles calculated. The departure and arrival time at the fishing ground must be decided.
