Quick Answer
To troubleshoot GPS problems in the field, check the device's antenna for obstructions, ensure it is receiving a strong satellite signal, and try resetting the device or recalculating the route.
Assessing the Environment
When GPS problems arise in the field, the first step is to assess the surrounding environment. Look for any obstructions that could be interfering with the GPS signal, such as trees, buildings, or power lines. If the device is in a valley or a canyon, try moving to a higher location to improve signal reception. In extreme cases, a clear view of the sky can be the difference between obtaining a signal and being lost.
Troubleshooting the Device
If the environment is not the issue, the next step is to troubleshoot the GPS device itself. Check that the antenna is clean and free of debris. Some devices have removable antennas, so make sure it is securely attached. If the device is in a water-resistant case, ensure it is not sealed too tightly, as this can block the signal. Try resetting the device by turning it off and on again, or try recalculating the route to see if the problem persists.
Alternative Navigation Methods
In the event that the GPS device is not functioning, it’s essential to have alternative navigation methods in place. This can include using a compass, map, and landmarks to navigate. A compass can provide a reliable reading, but it may not be as accurate as GPS. A map can provide a broader understanding of the terrain and help navigate using landmarks. Practice using these alternative methods before venturing into the field, and consider pairing them with a backup GPS device or a satellite phone for added security.
