Navigation Computers

Commercial and recreational mariners agree:  a navigation computer makes sight reduction calculations simpler and more reliable.  They're ideal for cramped spaces where juggling forms, tables, and almanacs makes navigation a chore.

The Celesticomp V is discontinued.


The StarPilot navigation computer offers a hand-held solution to ocean navigation that is more advanced than many computer programs.  Functions include:

  • Celestial sight reductions of all bodies (almanac accurate to 2100)
  • Mathematical and graphical solutions for position fixes
  • Great circle and rhumb line course calculations
  • Traverse and composite sailings
  • Current sailing
  • Piloting solutions
  • Lunar distance method of finding GMT
  • DR functions integrated with celestial functions
  • Sight reduction planner to plot full sky 

StarPilot uses a TI-89 graphing calculator.  If you already own a TI-89, software and upload packages are also available.  A personal computer and PC link kit are required to transfer the StarPilot software.

Packages include an illustrated user's guide with practice exercises and an emergency navigation booklet.
