🔍 Key Concepts

• Difference between terrestrial, celestial horizon, and celestial equator coordinate systems • How navigators practically use coordinates for fixing a ship’s position • Which circles/planes are mainly used in sight reduction and plotting vs. those more important in pure astronomy

💭 Think About

• Ask yourself: When you work a typical celestial sight at sea (Sun, stars, planets), which reference circles or planes do you actually use to get latitude and longitude? • Which option describes a path or plane related specifically to the Earth’s orbit around the Sun, rather than a general coordinate grid for positions? • Of the four choices, which one do you see most rarely in step‑by‑step navigation procedures and sight reduction tables?

✅ Before You Answer

• Identify which systems are the main reference frames for plotting positions on a chart or on the celestial sphere for navigation purposes • Check which term is mainly associated with the apparent annual motion of the Sun among the stars • Confirm from your study materials which three systems are emphasized as the basic coordinate systems for marine celestial navigation practice
