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:
“The military and the clergy cause us much annoyance; the clergy and the military, they empty our wallets and rob our intelligence.”
—Franz Grillparzer (1791–1872)
“Nothing changes my twenty-six years in the military. I continue to love it and everything it stands for and everything I was able to accomplish in it. To put up a wall against the military because of one regulation would be doing the same thing that the regulation does in terms of negating people.”
—Margarethe Cammermeyer (b. 1942)
“In all sincerity, we offer to the loved ones of all innocent victims over the past 25 years, abject and true remorse. No words of ours will compensate for the intolerable suffering they have undergone during the conflict.”
—Combined Loyalist Military Command. New York Times, p. A12 (October 14, l994)
