Author Topic: Estimated Position Question

From what I have been reading, using the line of position method requires an estimated position to be within approximately 50 nm of the true position. If the estimated position were too far from the actual position to get a good fix, would it be reasonable to use the fix to update the estimated position, then recalculate the sight reduction?

this question was also posted and answered in depth in the online classroom. the short summary is, yes that is what you do, and we have exercises in the course where we use NYC for the DR for pacific ocean sights and get to the right answer in about 3 iterations. those signed up for the course, check out long answer with examples in the classroom.
