A navigational problem in the Jan/Febr. 2004 edition of Ocean Navigator Magazine (#135) posed a question which involved a navigator shooting the sun to obtain an LOP. Since there is only one LOP there is therefore no fix, but the one of questions asked is What is the Estimated Position? I imagine that it is the position plotted on the LOP as being the closest from the DR. Does anyone agree?
Obviously in Coastal navigation, the estimated position is typically the position calculated from Course steered, log reading and taking tidal streams or current into account, but here the context is different.
