Global Positioning System (GPS)
GPS stands for Global Positioning System. It is a navigational system that can accurately locate your position anywhere
on the Earth. This technology is available to everyone, everywhere, day and night, and best of all, at no cost for use of the
navigational data. GPS uses 24 satellites which are located 11,000 miles above the Earth. These satellites transmit data back
to Earth and by locking onto this data, a GPS receiver can identify its precise location anywhere
in the world. GPS operates 24 hours a day, in all weather conditions, and can be used worldwide for precise
navigation on
land, on water and even in the air. Some of its many uses include: boating, fishing, hunting, hiking, and camping, as well as, a host of other activities where accurate positioning is required.
How GPS Determines Your Position
Every point on Earth can be identified by a specific address. By using two sets of numbers, referred to as coordinates,
which represent the exact spot where a horizontal line (latitude) crosses a vertical line (longitude), you can represent
any location precisely. GPS receivers report and record your current position - or the position of any place you've been
or would like to be - with latitude/longitude coordinates. GPS receivers also produce other critical navigation information,
including heading, bearing, distance-to-go, time-to-go, and more - anytime, anywhere, in any weather. Quality GPS receivers
cost less then $200.00.
