Quick Answer
To troubleshoot GPS signal loss in the wilderness, start by checking the device's satellite lock status, then assess the surrounding environment for obstructions, and finally attempt to reset or power cycle the device.
Assessing Obstructions
When navigating in the wilderness, GPS signals can be disrupted by various obstructions such as trees, hills, and buildings. To minimize interference, try moving to a higher vantage point, ideally at least 100 feet above the surrounding terrain. Alternatively, look for areas with clear lines of sight, like ridges or open fields.
Resetting or Power Cycling
If the GPS device is still not receiving a signal, try resetting or power cycling the device by turning it off, waiting 30 seconds, and then turning it back on. This can help clear any corrupted data or software issues that may be affecting the device’s ability to lock onto satellites. If the device has an SOS button or a similar emergency feature, press it to initiate a distress signal and potentially send a message to emergency responders.
Alternative Navigation Methods
If all else fails and you’re unable to obtain a GPS signal, it’s essential to have backup navigation skills. Consider using a map and compass to navigate, but first, learn how to use them effectively. The “map and compass” method involves using the sun, landmarks, and the compass to determine your bearing and location. Additionally, consider carrying a backup navigation device such as a paper chart or a handheld compass.
