Circle of position navigation
WebPosition Circle (distance by vertical sextant alt, horizontal angle or radar) : Position circle means a circle of positions. It is a curve or a set of all probable positions of ship, equidistant from a point. Out at sea, it is very common to use principle of position circle to find ships position, in day to day navigation. Example– Web1.3. Vector equation for the Circle of Equal Altitude. In Figure 3, let OP be the observer's position at the time of sight, and GP the geographical position of the celestial body at the same instant.The dot product of the vectors defined by the centre of the Earth and these points is the cosine of the angle between them, which is the zenith distance of the …
