The most important instrument was a navigators' diary, later called a rutter. Morgan horse, horse breed (see above). Time-keeping was by precision hourglasses, filled and tested to 1/4 of an hour, turned by the helmsman, or a young boy brought for that purpose.
JPMorgan Chase & Co., American banking corporation. Most sailors could use this instrument to take sun sights, but master navigators knew that sightings of Polaris were far more accurate, because they were not subject to time-keeping errors involved in finding noon. Morgan, South Australia. Latitude was determined with a "cross staff" an instrument vaguely similar to a carpenter's angle with graduated marks on it. Mount Morgan, California. This was placed in front of the helmsman. New Morgan, Pennsylvania. Another early invention was the compass rose, a cross or painted panel of wood oriented with the pole star or diptych.
Morganville - archaic synonym for the fictional town Shelbyville in The Simpsons. Basically, when the diptych's two sundials indicated the same time, the diptych was aligned to the current latitude and true north. Morganville, Washington. When combined with a plumb bob, some diptychs could also determine latitude. Morganville, Ohio. Most sailors have always been able find absolute north from the stars, which currently rotate around Polaris, or by using a dual sundial called a diptych. Morganville, New York. In the West, navigation was at first performed exclusively by dead-reckoning, the process of estimating one's present position based on the navigators' experience with wind, tide and currents.
Morganville, New Jersey. This can be accomplished using low-cost quartz clocks because the satellites send time correction signals to the GPS receivers. Morganville, Kansas. GPS uses 3D trilateration based on measuring the time-of-flight of radio waves using the well-known speed of light to measure distance from at least three satellites. Morganville, Georgia. A third source along with dead-reckoning will generally resolve to a single position. Morgantown, West Virginia. Signals from these two point establish a hyperbolic curve for possible positions.

Morgan Farm Area, Texas. Traditionally, three chronometers are kept in gimbals in a dry room near the center of the ship, and used to set a watch for the actual sight, so that the chronometers themselves do not risk exposure to the elements. Morgan City, Mississippi. If it is worn constantly, keeping it near body heat, its rate of drift can be measured with the radio, and by compensating for this drift, a navigator can keep time to better than a second per month.

Local noon is determined while shooting the azimuth as described above.
Morgan, Texas. Noon was an easy event to observe. Morgan, Minnesota. Longitude is calculated as a time difference between the same celestial event at different locations. Morgan, Georgia. Since periodic readings of the altitude will plot a sine wave, the maximum reading is the one used for local noon. William Alexander Morgan, anti Batista Guerrilla, said CIA operative active, executed by Castro   ,. Local noon is easily determined by recording periodic readings of the altitude of the sun.
film editor and director. The sun's angle over the horizon at noon was measured, and compared to the known angle at the same date as the known port. William Morgan (director), mid-20th Century U.S. However, prior to the development and formulation of its key principles in the latter part of the 17th century by Isaac Newton and Gottfried Leibniz, tables of the sun's altitude during the year for a known port were used. 1829–1883), Premier of South Australia 1878-1881. Calculating the anticipated altitude of the sun for a given day and known position is done easily using Calculus. William Morgan (Australian politician) (c. Determining latitude by the sun was a little more difficult since the sun's altitude at noon during the year changes for a given location.
Morgan, credited as having invented volleyball in Holyoke, Massachusetts on February 9, 1895. Navigators could determine their latitude by measuring the angular altitude of Polaris any time that it was visible (excepting, of course, in those southern latitudes from where it cannot be observed). William G. Anciently the home port was used as the known location, currently the Greenwich Meridian or Prime Meridian is used as the known location for celestial charts. William De Morgan (1839-1917), famed pottery and tile designer in Britain. Celestial navigation systems are based on observation of the positions of the Sun, Moon and stars relative to the observer and a known location. political figure in the 1920s. This is known as a fix.
William Morgan Butler, U.S. Addition lines of position can be measured in order to validate the results taken against other reference points. William Wilson Morgan, 20th-century astronomer. These lines of position can be plotted on a nautical chart, with the intersection being the ship's current location. William Morgan, scientist who won the Copley Medal in 1789 "for his two Papers on the values of Reversions and Survivorships, printed in the two last volumes of the Philosophical Transactions" (presumably in the field of actuarial science). This is done by correctly identifying reference points and measuring their bearings from the ship. William Morgan (anti-Mason), person whose disappearance sparked anti-Freemason hysteria in the United States. Periodically, the navigator needs to confirm the accuracy of the dead reckoning or estimated position calculations using position fixing techniques.

Trevor Morgan (EastEnders), character in the British soap opera EastEnders. A navigator uses the ship's last known position and dead reckoning, based on the ship's logged compass course and speed, to calculate the current position. Trevor Morgan (actor), United States actor. Traditional maritime navigation with a compass uses multiple redundant sources of position information to locate the ship's position. Thomas Hunt Morgan, geneticist. These were made obsolete by satellite navigation systems.
Sheryl Morgan, sprinter. The invention of the radio lead to radio beacons and radio direction finders providing accurate land-based fixes even hundreds of miles from shore. Morgan, First Amendment scholar. Later developments included the placing of lighthouses and buoys close to shore to act as marine signposts identifying ambiguous features, highlighting hazards and pointing to safe channels for ships approaching some part of a coast after a long sea voyage. Richard E. The development of accurate systems for taking lines of position based on the measurement of stars and planets with the sextant allowed ships to navigate the open ocean without needing to see land marks. Peter Morgan, ran the Morgan Motor Company. Nautical charts were developed to record new navigational and pilotage information for use by other navigators.

The first settlers of the Hawaiian Islands were said to have used these navigation methods to sail to the Hawaiian Islands from the Marquesas Islands. John Tyler Morgan, U.S. The guild secrets might have been lost, had not one of the last living navigators trained a professional small boat captain so that he could write a book.
Morgan, American financier and banker. Generally each island maintained a guild of navigators who had very high status, since in times of famine or difficulty, only they could trade for aid or evacuate people. P. These, and outrigger canoe construction methods, were kept as guild secrets. J. In Eastern Polynesia, navigators, in order to locate directions at various times of day and year, memorized extensive facts concerning:. John Morgan (poker player), winner of $1,500 No Limit Hold'em event at the 1996 World Series of Poker. The Polynesian navigators routinely crossed thousands of miles of open ocean, to tiny inhabited islands, using only their own senses and knowledge, passed by oral tradition, from navigator to apprentice.
