The history of navigation is described briefly, with particular attention to the rapid progress that has taken place since 1940. The problems still to be solved are outlined, and possible directions of future progress in navigation are discussed. The challenge for the future is highlighted by the observation that it is significant that in one hundred and twenty years, mankind has passed the Â¿oats, sonic and thermal barriers,Â¿ and now is in a position to discuss openly the ultimate speed barrier of all physical matter.
