Peer Reviewed

Abstract:	Almanac and Astronomical Ephemeris, first published for the year 1767. Its origin and early history are reviewed primarily to see how the provision for astronomical navigation has been’ changed to meet the changing and expanding requirements of navigation. Against this background consideration is given to the changes that the increasing use of computers and other methods in terrestrial navigat’ion, and the extension to space navigation, may bring in the last third of t’he twentieth century. It is concluded that little change will be required.
