Portable GPS FAQs
What are some military applications of GPS?
The military applications of GPS are numerous. Naturally, the technology helps with navigation, allowing soldiers to find their destinations in the dark or in unfamiliar areas. Being able to pinpoint coordinates is also helpful for locating multiple troops and supplies at a distinct rendezvous point. For these and other reasons it is easy to see why GPS technology was first developed by the U.S. Navy, and the technology remains valuable for both soldiers and commanders today.
Besides the navigational possibilities it provides, what other civilian applications benefit from GPS technology?
GPS signals benefit numerous civilian applications, sometimes without us even realizing it. Naturally, the technology is used to improve aviation, maritime and land travel. The technology has also dramatically changed the way we survey land. Researchers can now more closely explore the environment, including the atmosphere and gravity field. GPS survey equipment can also directly measure the motion of faults in earthquakes. In short, GPS technology is used in a multitude of ways, and these applications are sure only to increase as the technology becomes even more common.
What is “geocaching,” and how do you play?
Geocaching is a treasure-seeking game that utilizes handheld GPS technology. It is roughly based on an old English game called letterboxing, in which a player or team seeks the treasure “cache” left by another player or team. This cache is usually a box full of small, white elephant-esque surprises. The cache is hidden at specific coordinates, and it is the other team or player’s job to use their GPS to find those coordinates and the treasure. The hobby is an international phenomenon that continues to grow in popularity, especially as handheld GPS devices continue to become more prevalent and affordable.
