Celestial navigation

Foundations and methods of celestial navigation for offshore sailing — taught in a technically sound, precise, and practical manner.

Nautical Specialist Module: Celestial Navigation

Celestial navigation is a classical yet highly precise method of determining position at sea. It enables independent navigation without electronic systems and provides a deep understanding of the movement of the sun, moon, planets, and stars. This module is designed for anyone who wants to expand their offshore competence or learn the fundamentals of celestial navigation.

Module Content

The module covers all essential foundations and methods of celestial navigation:

  • Introduction to celestial navigation
  • Structure and operation of the sextant
  • Measuring celestial altitudes (sun, stars, planets)
  • Corrections: index error, dip, refraction, parallax
  • Calculation of true altitude and intercept
  • Position lines and the intercept method
  • Meridian altitude: latitude and longitude at noon
  • Calculations using the Nautical Almanac and tables
  • Practical exercises and example problems

Course Structure

The module is clearly structured and adapted to the participant’s level of knowledge:

  • Theoretical introduction to principles and methods
  • Practical exercises with sextant and navigation tables
  • Calculation of real observations
  • Optional: advanced level for SHS preparation
  • Individual guidance in a calm learning environment

Requirements

  • No prior knowledge required
  • Basic navigation skills helpful but not necessary
