Trevor, Thank you very much for your explanation. I forgot about Sat Nav indeed. Do you know when approximately did they start using it? (I suppose, not earlier than late 70-s). The manuals I cited were written in the 60-s when no Sat Nav existed. I am just trying to understand when CelNav was replaced by various satellite-based systems as a main tool of finding position on commercial and navy ships. Alex. P.S. LORAN only works near a shore, correct? The only precise means available in the middle of an ocean are CelNav and satellite-based systems, correct? A
