Global positioning system, английский
- A device which uses satellite signals to accurately determine a fishing vessel's position and course.
- (gps) a satellite based radionavigation system providing continuous worldwide coverage. it provides navigation, position, and timing information to air, marine, and land users.
- Глобальная позиционирующая система, гпс
- A space-based navigation system in which orbiting satellites provide extremely accurate three-dimensional coordinates. it is officially called navstar-gps, which is short for (navigational signal timing and ranging—global positioning system) but is commonly known as gps. it was designed for and is operated by the u.s. military, which makes segments of it available for civilian use as a “public good” without charge. it can be conveniently divided into three parts. • control segment consists of tracking stations lo- 135 global cated around the world, under the overall control of a master facility at schriever afb in colorado. • space segment consists of at least 24 satellites that orbit the earth twice daily and are known as space vehicles (svs). these are spaced so that between five and eight can be sighted from any point on earth at any time. after locating at least four of them, a gps receiver can use a simple mathematical technique called trilateration to deduce its location. • public user segment has been intentionally downgraded from military precision, but still allows anyone with a gps receiver to determine latitude and longitude within 100 meters; altitude within 156 meters, and time of day within 340 nanoseconds. like any electronic device, a gps receiver can fail or malfunction, so the prudent navigator will always carry back-up in the form of traditional devices such as leadline and logline, sextant and navigation tables, chronometer, etc. see also galileo, satellite navigation.

- A radio navigation system developed by the u.s. department of defense that uses a constellation of 24 earth satellites, which are monitored by ground-based control stations, to provide precise, continuous worldwide positioning and timing information.
