used a sand-glass to measure the time that his ships were at sea. With today’s marine chronometer‚ a measurement of time in such a precise and accurate way that it’s used as a portable time standard and to determine longitude by means of celestial navigation‚ he would’ve had a more precise inquiry of the time it takes him to sail from one place to another. Along with Christopher Columbus’s use of the sand-glass to keep time while at sea‚ he also used a nocturnal‚ which is an tool used in determining

Pacific was explored by some great navigators who sailed from different parts of the world like Captain James Cook who used navigation tools like sextant and radars to navigate the Pacific. On the other hand‚ Polynesia was explored around 1000 years ago by navigators who used the waves‚ stars‚ and the flights of birds to set their voyage and travel through the Pacific Ocean. “In hand-built‚ double-hulled canoes sixty feet long‚ the ancestors of today ’s Polynesians sailed across a vast ocean area

The Law of Navigation Law Number Four is called “The Law of Navigation.” The by-line for this chapter reads‚ “Anyone can steer the ship‚ but it takes a leader to chart the course.” That by-line reflects something that anyone can beat time‚ but not everyone is a conductor. Anyone can learn how to play a piano but not all will become a pianist. Everyone can learn to swing a golf club but not everyone can become a golfer. Regarding conducting‚ more than a few famous conductors have said that they can

Target means any object fixed or moving whose position and motion is determined by measurements of range and bearing on radar. 2. Relative Course means the direction of motion of a target relative to own ship’s position expressed as an angular displacement from north. It is deduced from a number of measurements of target range and bearing or own ship’s radar.

DISTANCE CALCULATION Because of the near-spherical shape of the Earth (technically an oblate spheroid) ‚ calculating an accurate distance between two points requires the use of spherical geometry and trigonometric math functions. However‚ you can calculate an approximate distance using much simpler math functions. For many applications the approximate distance calculation provides sufficient accuracy with much less complexity. The following approximate distance calculations are relatively simple
