Best Answer

Sailors used a compass or an astrolabe. a compass points North so you know your direction. an astrolabe can tell your location by using the sun as a reference point but you might need a star chart to use it. If you were traveling at night you would use the star char5t and the North Star to tell direction.

The Navigational aids that explorers would have used included:

  • Astrolabes - calculating latitudes

  • Telescope - Hans Lippershey (c1570-c1619) credited with the invention. The telescope was introduced to astronomy in 1609 by Galileo Galilei

  • Charts and Maps - Cartography or map making was an important Renaissance skill

  • Compasses - Enabled Renaissance sea men to find their bearing in the fog

  • Cross-staffs - Used to measure the angle of the Sun or a star above the horizon

  • Nocturnals - Measuring and timekeeping instrument

  • Quadrants - Measuring and timekeeping instrument

  • Traverse boards - Navigation instrument - older version of Astrolabe

  • The Hour-glass, Minute-glass and Sun-dial - timekeeping instruments

  • Almanacs - which forecast precisely where the the sun, moon, planets and selected navigational stars, are going to be, hour by hour, years into the future
