Description: Tasks for navigation Task number: A1.1 Topic: Celestial Navigation Acti :Work out a sight using meridian altitude of sun. Minimum number of times that activity should be performed: 4 (2 each phase) Sample calculation: (Latitude by meridian altitude- Sun) On 4th April 1998, in DR position 35°10'N 148°18'E, the sextant meridian altitude of the Sun's lower limb was 60°10.3'. If IE was 2.2' off the arc, and HE was 12 meters, find the latitude and the position line.
