Frank,
Thanks for your quiz.
Offering the following solution :
Keep assuming known Latitude at N25°5 , and plot both MOON UL and SUN LL height errors for different Longitudes : here I did it for W076°, W076°30', W075°30' and 075°45'
See the results in the attachment.
Then plots errors vs. Longitude, which yields our two results :
Errors are equal - or almost equal - for LON = W075°35.5' and they are close from 12', hence HOE is close from 46m or 150 ft.
(1) : This result can be refined with better hand drawn sketch.
(2) : Difficult anyway to get any reliable fix through intersecting LOP's which are almost parallel (GDOP)
(3) : Big Ship indeed ...
(4) : Thanks again
Kermit
