Exploring azimuth tables: is part of a set of exercises aimed at calculating the height and azimuth of the sun, and ultimately finding its position at sea using a sextant without a scientific calculator but with tables.
This page only provides the answers to the four exercises for calculating the sun’s azimuth.
Exploring sun’s azimuth tables: answer exercise A
P = 060° 30′,1 NW; L = 38° 06’N; D = 08° 15′,5 N
PART 1 A :
lc = 0,44
dc = 0,17
same name
P < 90°
zc = lc – dc Z = obtuse
zc = 0,27
PART 2 A :
L = 38 °,1 N; Z = obtuse ; zc = 0,27
Z = 102°
P = NW / Zv = 360° – 102° = 258°
Exploring sun’s azimuth tables
answer exercise B
P = 39° 39′,8 SE ; L = 05° 08′,9 S; D = 18° 18′,9 S
PART 1 B :
lc = 0,11
dc = 0,52
same name
P < 90°
zc = dc – lc Z = acute
zc = 0,41
PART 2 B :
L = 5°,2 N; Z = acute; zc = 0,41
Z = 68°
P = SE / Zv = 180°- 68° = 112°
Exploring sun’s azimuth tables: answer exercise C
P = 59° 44′,7 NE; L = 30° 28′,5 N; D = 20°20′,6 S
PART 1 C :
lc = 0,34
dc = 0,43
not same name
P < 90°
zc = lc + dc Z = obtuse
zc = 0,77
PART 2 C :
L = 30°,5 N; Z = obtuse; zc = 0,77
Z = 123,5°
P = NE / Zv = 123,5°
Exploring sun’s azimuth tables
answer exercise D
P = 32° 30′,8 NW L = 05°53′ N D = 45°13′ N
PART 1 D :
lc = 0,16
dc = 1,87
same name
P < 90°
zc = dc – lc Z = acute
zc = 1,71
PART 2 D :
L = 05°,9 N Z = acute zc = 1,71
Z = 30°,5
P = NW / Zv = 360° – 30°,5 = 329°,5
