Quick Answer
To handle GPS failures while hiking, bring a map and compass as essential backups, and learn to use them effectively. This includes orienting yourself with natural navigation methods and understanding map scales and coordinates. It's also crucial to have a basic knowledge of GPS functionality and alternative navigation methods.
Understanding GPS Functionality
When relying on GPS for navigation, it’s essential to understand the limitations and potential failures. Modern GPS devices use a network of satellites orbiting the Earth to provide location data. However, these signals can be interrupted by tree cover, mountainous terrain, or even the weather. Always keep in mind that GPS signals can be lost, and it’s crucial to plan for alternative navigation methods.
Developing Alternative Navigation Skills
To navigate effectively, develop your skills in reading maps and using a compass. This includes understanding map scales, grid references, and contour lines. Practice orienting your map with natural navigation methods, such as using the sun, stars, and landmarks. Consider investing in a compass with a declination adjustment, which allows you to account for local magnetic variations.
Creating a Backup Plan
Before venturing out on a hike, create a backup plan in case of GPS failure. Bring a detailed topographic map of the area, a compass, and a spare set of batteries for your GPS device. Consider bringing a paper copy of your GPS tracks or using a GPS device with a paperless chartplotter feature. Always inform someone of your itinerary and estimated return time, and consider carrying a personal locator beacon (PLB) or satellite phone in case of an emergency.
