Answers: Science of directing a craft by determining its position, course, and distance traveled. Early mariners followed landmarks visible on shore and studied prevailing wind for clues to direction. The Phoenicians and Polynesians sailed out of sight of topography and used the stars to set their course. The compass (first used by the Chinese c. 1100) was the first navigational aid that gave a constant hint point, though its accuracy was restricted, especially in heavy sea. Modern compasses are stabilized by gyroscopes and housed in binnacles that compensate for the craft's motion. Ship speed was first calculated by dropping overboard a log attached to a wobble of line knotted at regular intervals; the number of knot exposed while the log drifted and a sandglass emptied gave the vessel's speed contained by knots (nautical mph). Charts are another essential navigational tool. Fixing a position requires charts detailing known locations, together next to instruments that calculate a vessel's bearing relative to them. The earliest instrument for determining latitude be the quadrant, which measured the altitude of the polestar or the noonday sun. Other early instruments included the sextant and the astrolabe. Longitude (used for navigation with increasing nouns in the 17th – 18th century) was fixed using chronometers and table showing positions of celestial bodies throughout the year. In the 20th century, radio beacons and satellite networks allowed aircraft and ships to determine their position. Dead reckoning uses an accurate history of a vessel's headings and speeds drawn from gyroscopes and from computerized measurements of the craft's acceleration.

Early Navigational Techniques
In ancient times, mariners navigated by the guidance of the sun and stars and landmark along the coast. The Phoenicians were probably the most daring of the ancient navigator. They built large ships and, traveling out of sight of domain by day and by night, probably circumnavigated Africa. The Polynesians navigate from island to island with the help of guide stars, wisdom of which was passed from generation to equals.
In England, Queen Elizabeth I did much to establish navigation laws, giving additional powers to Trinity House, a guild that have been created in 1514 for the piloting of ships and the regulation of British navigation. During this spell the study of bodies of water, or hydrography, was given much attention, and harbors and the outlets of rivers be surveyed and buoyed. A tremendous advance in navigation have taken place with the introduction of the compass. Early in the 15th cent. here was progress by the Portuguese under the regulation of Prince Henry the Navigator, who built an observatory and formulated tables of the declinations of the sun; collected a great amount of nautical information, which he placed in practical form; made charts; and sponsored expeditions that lead to numerous discoveries.
Modern Navigational Tools
The next great revolution in navigation occur in the 20th cent., when radio signals came into wide open use. The development of radar, loran, and radio direction finding during World War II caused fundamental change in navigational practice; a mariner or pilot today can turn on a Loran or Global Positioning System receiver and determine position and course to inwardly a few yards. Inertial guidance systems, most often used to navigate submarines, aircraft, and spacecraft, allow navigation minus contact with a ground base. In such systems, a computer navigate the vehicle with the aid of an inertial navigator device, which consists of a gyroscope to indicate direction and an accelerometer to measure change in speed and direction. Inertial guidance systems and terrain-following radar allow a cruise missile to fly a thousand miles and hit its designated target.
