Celestial Navigation

Offshore navigators use celestial navigation as a backup for the GPS. Use a sextant for taking the altitude of a celestial body and OpenCPN to plot the celestial circle of position instead the LoP -Line of Position-. Repeat this and take at least three sights. You easily can check if any danger is near your fix, and the uncertainty in your position.

Coastal Navigation

Using the GPX utility is possible to plot on an electronic nautical chart the three types of lines of position used in coastal navigation:
  • Bearing
  • Range
  • Horizontal angle
Free software to create the GPX file that serves as an input to OpenCPN is available at

Up todate tracks of tropical system can be imported into OpenCPN with the GPX import facility. This makes planning easy as the tropical system track is displayed on your normal navigation chart. Read more here.
