      Descriptive Video


      Yup…..there’s no GPS in space! We rely totally on GPS and similar satellite navigational systems such as Glonass, Galileo and Beidu. Unfortunately a large solar X flare or space explosion could take out enough satellites to make the system unusable. Celestial Navigation has been around for centuries and is as reliable as the Sun, Moon, Planets and Stars! “Celestial Navigation Basics & Equipment” teaches you how to determine your position using simple spherical trigonometry. All examples feature sample ScicosLab code and manual sight reduction such as The Nautical Almanac, HO.249/AP3270.
