Masters Mate

From Daniel Baxter:

A Celestial Navigation Program. Master's Mate handles most of the calculations involved in this traditional, but still widely used method of navigation at sea. The features are organised using a simple tab system and are integrated to allow continuous progression to a final solution.

Features include:

• Interpolation of GHA and Declination values
• Correction of Sextant Altitude for Dip, Parallax, Refraction and Semi-Diameter
• Sight Reduction and the calculation of Latitude from a noon sight.

  What's new in this version:

  • Allowance for the correction 'v' to GHA for sights taken of Planets or the Moon
  • Handling of 'Dip Short' sights, for navigators who cannot use a true horizon
  • Minor improvements to source code for added stability
