Syn. -- GPS.
[ RH ]

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. [ RH ]

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. https://web.archive.org/web/20011125121826/http://www4.nationalacademies.org/beyond/beyonddiscovery.nsf/web/gps?OpenDocument [ PJC ]

a. [ Homo- + systemic. ] (Biol.) Developing, in the case of multicellular organisms, from the same embryonic systems into which the secondary unit (gastrula or plant enbryo) differentiates. [ 1913 Webster ]

n. (Biol.) The complex of cells, cellular processes, and substances within and diffused throughout an organism which allow the organism to counteract or destroy noxious foreign substances introduced into the body, destroy infectious agents such as bacteria and viruses, destroy malignant cells, and remove cellular debris, thus protecting the organism against many of the potentially harmful external agents and internal events that could lead to sickness or death. The system has numerous interacting components, including circulating antibodies, antibody-producing cells, white blood cells and lymphokines, lymph tissue and lymph nodes, and stem cells which may differentiate into other types of cell, together with the thymus and spleen. The system is responsible for the phenomenon of immunity{ 3 }. See also immunoglobulin and antibody. [ PJC ]

n. (Anatomy, Neurophysiology) A group of neural structures in the brain below the cerebral cortex, centered on the hypothalamus and including the hippocampus and amygdala, involved with control of emotion, motivation, memory, and some homeostatic regulatory processes. [ WordNet 1.5 ]

At the most ancient part of the human brain lies the spinal cord; the medulla and pons, which comprise the hindbrain; and the midbrain. This cobination of spinal cord, hindbrain, and midbrain MacLean calls the neural chassis. It contains the basic neural machinery for reproduction and self-preservation, . . . MacLean has distinguished three sorts of [ more recent brain structures controlling ] the neural chassis. The most ancient of them surround the midbrain. . . . We share it with the other mammals and the reptiles. It probably evolved several hundred million years ago. MacLean calls it the reptilian or R-complex. Surrounding the R-complex is the limbic system, so called because it borders on the underlying brain. (Our arms and legs are called limbs because they are peripheral to the rest of the body.) We share the limbic system with other mammals, but not, in its full elaboration, with the reptiles. It probably evolved more than one hundred fifty million years ago. Finally, surrounding the rest of the brain and clearly the most recent evolutionary accretion, is the neocortex. Carl Sagan (The Dragons of Eden, New York, Random House, 1977). [ PJC ]

(Elec.) A system or wireless telegraphy developed by G. Marconi, an Italian physicist, in which Hertzian waves are used in transmission and a coherer is used as the receiving instrument. [ Webster 1913 Suppl. ]

pos>n. A system of weights and measures originating in France, the use of which is required by law in many countries, and permitted in many others, including the United States; the system is also called by its French name, Le Système International de Unités (abbreviated SI). The principal unit of length is the meter (see Meter). From this are formed the are, the liter, the stere, the gram, etc. These units, and others derived from them, are divided decimally, and larger units are formed from multiples by 10, 100, 1, 000, and 10, 000. The successive multiplies are designated by the prefixes, deka- (formerly deca-), hecto-, kilo-, and myria- (seldom used); successive parts by deci-, centi-, and milli-. The prefixes mega- and micro- are used to denote a multiple by one million, and the millionth part, respectively; giga- and nano- denote multiples of one billion (1, 000, 000, 000) and one billionth, respectively. The prefix for one trillion (10¹²) is tera, and for one trillionth (10^-12) is pico; for one quintillion (10¹⁵) peta, and for (10^-15) (one quintillionth) femto; for (10^-18) atto. See the words formed with these prefixes in the Vocabulary. For metric tables, see p. 1682. [ 1913 Webster +PJC ]
