What Should You Do If GPS Guidance Is Inaccurate?

Using a Compass

A compass is an essential tool for navigation when GPS is unavailable. Hold the compass level and ensure the magnetic needle is aligned with the direction-of-travel arrow. Take a bearing from a known landmark or use a map to estimate your direction. Use the compass to navigate in a grid pattern, checking your position frequently to avoid getting lost.

Using Maps

Maps are an essential backup to GPS. Study your map before setting out and identify key features such as roads, rivers, and landmarks. Use a map and compass together to estimate your location and plan your route. Take a photo of your map and save it on your phone or write notes on the map with a pencil to aid in future navigation.

Natural Navigation Techniques

Natural navigation techniques can be used to estimate your location and direction. Use the sun to estimate direction (sun rises in the east and sets in the west) and use shadows to estimate time. Look for natural features such as the shape of trees, the direction of water flow, and the position of constellations to aid in navigation. Use your knowledge of the terrain and environment to estimate your location and plan your route.
