Modern navigators may not use Astro very often, but when the GPS goes down they will need the book, so it is an essential volume to have on the bridge as backup. It is a practical working guide to the art and science of celestial navigation. The coverage of calculation methods makes this volume equally applicable to military and merchant navy officers and leisure users. Chapters include: The Celestial Sphere; Time Systems; Practical Sights; Taking Reducing Plotting.
