What Can A GPS Handheld Unit Do For The Hiker?
Handheld GPS units are a hikers best friend. A handheld GPS unit can give people the freedom to explore the experience hiking in the wilderness areas that they have not attempted before.
A typical handheld GPS unit is powered by standard batteries and is 2 to 3 inches wide and 4 to 6 inches long. Handheld GPS units which can be used for hiking in the wilderness, use satellites orbiting over 12,000 miles above the earth to determine the position of the handheld GPS unit on the ground. There are several physical elements which may prevent a handheld GPS unit from receiving a satellittes signals.
Waypoints: A waypoint is a single point location. It can be saved in the handheld GPS unit’s memory.
Tracks: A track is essentially a route that is made up of many linked sequential locations which a handheld GPS unit automatically creates and saves as you hike in the wilderness. Waypoints, routes, and tracks are the three principal categories of locations that are fixed by a hiker in a handheld GPS unit. An understanding of these three basic categories gives the hiker insight into how a handheld GPS unit can help one navigate and explore safely while hiking in the wilderness.
Never Get Lost Again!
It was also at this same time that I decided to purchase a handheld GPS unit. Having a GPS unit would have provided a sense of security and a piece of mind. Using a handheld unit deftly takes the place of using a compass. Handheld GPS units have been gaining popularity over the last decade. Global positioning systems were originally designed and developed by the United States Department of Defense. GPS technology is made possible by utilizing the 24 to 32 satellites currently circling the earth. Once the GPS navigational receivers receive the triangulation signal, the system is able to calculate the exact position of the receiver.
While the technology involved in making GPS systems work sounds complicated. Actually, using a handheld GPS unit is extremely straightforward.
