I came across this item in an article on celnav on the website tiititudorancea.com.
" Traditionally, a navigator checked his chronometer from his sextant, at a geographic marker surveyed by a professional astronomer".
Could the members throw some light on the method referred to here and its history. The marker is also referred to as a "Harbor marker"
Do any of these markers still exist?
