Modern navigators may not use celestial navigation very often, but STCW demands that seafarers are able to use these skills so that if the GPS goes down they will be able to navigate. This is therefore 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.
