Fred, I afraid they did not. I am talking of early 60-s. It is to this epoch that the first submarine missiles and unguided Minuteman belong. I doubt that in the early 60-s Americans had a satellite nav comparable to Cel Nav in accuracy. All this can be of course checked on the Internet. The guidance of missiles and Sat Nav systems, when they started to use them. So here is a clearly stated Question to the list: When the first satellite based nav system came into use, which superceded Cel Nav in accuracy ? (I am sure someone has a ready ans). Alex.
