← HistoryWhich navigational outcome occurred when medieval Islamic astrolabes incorporated horizon-based coordinate systems at sea?
A)More accurate determination of solar altitude✓
B)Reduced reliance on magnetic compasses
C)Simplified celestial chart projections
D)Improved lunar phase prediction accuracy
💡 Explanation
When Islamic astrolabes used horizon coordinate systems, the observer could directly measure altitude angle above the horizon for celestial objects because adjusting the astrolabe mimicked observations. More accurate determination of solar altitude resulted, rather than the alternatives, which involve completely different underlying mechanisms independent of coordinate system translation.
