Celestial Navigation

Self-reliant navigation when electronics go dark. Learn the full workflow—sextant handling, timekeeping, sight planning, reduction methods, and plotting—so you can fix position by the sun, moon, planets, and stars on ocean passages and exams.

Start here: Core texts and sight-planning guides—browse Celestial Navigation.
Tables & data: Keep current Nautical Almanacs & Tide Tables for reliable reductions.
Practice & tools: Pair books with a quality sextant and plotting kit; see Sextants.
