(gl[=o]"b'l p[-o]*z[i^]sh"[u^]n*[i^]ng s[i^]s"t[e^]m)
A worldwide system of electronic navigation in which a
vessel, aircraft or missile determines its latitude and
longitude by measuring the transmission time from several
orbiting satellites. GPS is more precise than any other
navigation system available, yielding position accurate
within 10 meters 95% of the time.
Syn: GPS.
[RDH]
Note: The precision of the GPS is dependent upon the very
high timing accuracy of atomic clocks. Although the
military originally intentionally degraded the signal
and thus the accuracy for civilian users, GPS was
nevertheless more precise than any other navigation
system available. In 2000, President Clinton issued an
executive order discontinuing the degrading of the
signal for civilians.
[RDH]
On June 26, 1993 . . . the U.S. Air Force
launched the 24th Navstar satellite into orbit,
completing a network of 24 satellites known as
the Global Positioning System, or GPS. With a GPS
receiver that costs less than a few hundred
dollars you can instantly learn your location on
the planet -- your latitude, longitude, and even
altitude -- to within a few hundred feet.
This incredible new technology was made possible
by a combination of scientific and engineering
advances, particularly development of the world's
most accurate timepieces: atomic clocks that are
precise to within a billionth of a second.

GPS
(GPS) A system for determining postion on the
Earth's surface by comparing radio signals from several
satellites. When completed the system will consist of 24
satellites equipped with radio transmitters and atomic clocks.
Depending on your geographic location, the GPS receiver
samples data from up to six satellites, it then calculates the
time taken for each satellite signal to reach the GPS
receiver, and from the difference in time of reception,
determines your location.
