Quick Answer
For desert navigation, alternatives to GPS include using a compass, map reading skills, and celestial navigation techniques such as using the sun and stars to determine direction. These methods can be used in conjunction with or as a backup to GPS navigation. They require practice and knowledge to use effectively.
Understanding Compass Navigation
A compass is a simple yet effective tool for navigation. To use a compass, first orient the compass to magnetic north by aligning the magnetic needle with the direction-of-travel arrow. Next, use the compass to determine your direction of travel. This can be done by setting the direction-of-travel arrow to point towards your destination and using the magnetic needle to guide you.
Map Reading and Landmarks
Map reading skills are essential for navigation in the desert. To use a map effectively, first identify your location and the location of your destination. Next, use landmarks such as mountains, valleys, and bodies of water to help guide you to your destination. Be sure to use a topographic map that includes contour lines to help you identify elevation changes and navigate through the desert.
Celestial Navigation
Celestial navigation involves using the sun and stars to determine direction and location. To use celestial navigation, first identify the North Star, also known as Polaris, which is located in the constellation Ursa Minor. Next, use the sun to determine direction by observing the time of day and the position of the sun in the sky. By using a combination of these techniques, you can navigate effectively in the desert even without a GPS device.
