Advancing LOPs, ContinuedFigure 9-14. A fix from several LOPs.Three lines of position by observation, like those obtained in piloting, donot always intersect exactly. Quite often a triangle is formed. If one ormore of the LOPs must be advanced, the triangle is likely to be larger.Frequently, the center of the triangle is assumed to be the fix.If, however, one or more lines have been advanced, more weight may begiven to a line that has not been advanced, or to a line that the navigatorhas more confidence in; for example, favoring a first magnitude starover a third magnitude star. In figure 9-14, note that the plots are madefrom three separate APs, using the same assumed latitude but differentassumed longitudes.9-30
