Military
Military applications include devices similar to consumer sport products for foot soldiers (commanders and regular soldiers), small vehicles and ships, and devices similar to commercial aviation applications for aircraft and missiles. Examples are the United States military's Commander's Digital Assistant and the Soldier Digital Assistant. Prior to May 2000 only the military had access to the full accuracy of GPS. Consumer devices were restricted by selective availability (SA), which was scheduled to be phased out but was removed abruptly by President Clinton. Differential GPS is a method of cancelling out the error of SA and improving GPS accuracy, and has been routinely available in commercial applications such as for golf carts. GPS is limited to about 15 meter accuracy even without SA. DGPS can be within a few centimeters.

Famous quotes containing the word military:
“[I]t is a civil Cowardice to be backward in asserting what you ought to expect, as it is a military Fear to be slow in attacking when it is your Duty.”
—Richard Steele (1672–1729)
“His ugliness was the stuff of legend. In an age of affordable beauty, there was something heraldic about his lack of it. The antique arm whined as he reached for another mug. It was a Russian military prosthesis, a seven-function force-feedback manipulator, cased in grubby pink plastic.”
—William Gibson (b. 1948)
““My ancestors were all famous for military genius.”
My Lady smiled graciously. “It often runs in families,” she remarked: “just as a love for pastry does.””
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
