Quick Answer
To prepare for extended periods without GPS, learn basic navigation skills, carry a map and compass, and use celestial navigation techniques. Familiarize yourself with the terrain and create a mental map. Practice using landmarks and dead reckoning to estimate your location.
Mapping and Charting Techniques
When creating a map for navigation, use a scale of 1:50,000 or larger to include essential details. Include natural and man-made features such as rivers, forests, roads, and buildings. Use a ruler to draw a grid and mark your starting and ending points. Consider marking potential routes and hazards.
Celestial Navigation
To use celestial navigation, learn to identify the North Star (Polaris) and recognize the constellations. Use a sextant or a smartphone app to measure the sun’s altitude and calculate your latitude. Practice taking readings during the day and using the shadow stick method to estimate the sun’s position.
Dead Reckoning and Landmark Navigation
Dead reckoning involves estimating your location based on your previous route and speed. Practice calculating your progress using a speed and distance table. Learn to recognize and remember distinctive landmarks such as mountain peaks, water towers, and unique rock formations. Use these landmarks to estimate your location and adjust your course accordingly.
