Quick Answer
Relying solely on a GPS can lead to decreased accuracy, reduced situational awareness, and increased risk of getting lost in dense forests or areas with limited satellite signal.
Limited Satellite Signal
Relying solely on a GPS can be disastrous when the satellite signal is weak or non-existent. In areas with dense foliage, such as forests, or near tall buildings, the signal can be blocked or weakened, making it difficult to get a fix on your location. This can happen in up to 30% of the time, depending on the environment and satellite geometry.
Compass Advantage
A compass, on the other hand, provides a more reliable and consistent means of navigation. Unlike GPS, a compass does not rely on external signals and can provide a clear indication of direction, even in areas with limited visibility. By using a compass in conjunction with a map, you can ensure that you’re navigating correctly, even when the GPS signal is weak.
Combining GPS and Compass
The best approach is to use both GPS and compass together. By combining the two, you can ensure that you’re navigating accurately and making up for the limitations of each device. This is especially true when traveling in areas with limited satellite signal, such as dense forests or near tall buildings. By using a compass to triangulate your position and a GPS to provide a more precise location, you can increase your chances of staying on course and avoiding getting lost.
