Sažetak
In coastal navigation , if two horizontal angles between three fixed objects above the sea surface can be determined from a point of observation , two circular position lines are determined that cut in two points.One point of intersection is located in the central object and the other in the observation point itself.The coordinates of the observation point can be determined in various ways ; for example , by calculating the radius of the circle - position line, or by graphical construction etc.As a difference , this paper offers a new approach in calculating distance off.The equations presented here enable distance off computation between the point of observation and three suitably selected shore objects when two horizontal angles between the objects are known and obtained by sextant measurement or by bearing difference of three objects.
