In the diagram at 16:00 you drew LHA from the celestial body but LHA It is the angle between the meridian of your Assumed Position and the meridian of the geographical position of the celestial body.

Sanjeev, if its zero deg zero min, it will not matter if you add or subtract
@sourabhkashid68415 жыл бұрын
Adding and substraction depends upon the lattitude and declination of sun. Your SMT WILL BE YOUR GMT you will be in zone zero.

Sir !why is position line perpendicular to azimuth? & What is the Meaning of position line sir?
@SteeringMariners4 жыл бұрын
Position line is perpendicular to the bearing (azimuth). the bearing line and position line work as a bearing and range (like for a normal land-based objects). Statistically, the position line tells us that somewhere on it is the position of the vessel. we only know where the exact position is when 2 or more position lines intersect.

You are not able to plot the position obtained by Longxchron. What is the big deal in showing the PL , most of you guys don't know what is to be done further.

Sir, please explain how to draw the PL and the position from which it is drawn. In the video the method of drawing the PL is almost similar to that of intercept , except the distance of the DR position is not shown.

@martintimothy19153 жыл бұрын
Ok, say we timed the transit of a star across the prime meridian at 10.00 pm local, since the sidereal day is 23 hours, 56 minutes 4.0916 seconds, we know if we were stationary the same star would be back on the meridian at 9:53:55.084 the following night .. suppose we were at sea and heading along the same degree of latitude. Compute longitude by timing the transit of the same star, thus if it crossed the meridian early we have gone a set distance converted to degrees of longitude east, conversely it the transit was later than 9:53:55.84 we would have gone a set distance converted to degrees of longitude west. How does that sound .. cheers from Brisbane Au :)
