The "Star Map" module provides a polar and linear plot of the sky at a given time and geographical position. Calculations for any day/year, (accuracy based on the calculations used in the module).Provides numerous data: Such as GHA, SHA, DEC, Semi-Diameter, Horizontal Parallax, and Equation of Time.
Astronomical data for the Sun, Moon, 4 planets and 57 standard Navigation Stars (of the Nautical Almanac), and some other major stars.The "Star and Planet" module provides astronomical data, similar to that obtained from a Nautical Almanac. Calculates and draws of Lines Of Position (LOP), and calculates the Latitude and Longitude.Standard altitude corrections are performed including: Index Error, Height of the Eye, Parallax, Semi-Diameter, and Refraction.

The software thus also provides various astronomical data, such as the data obtainable from the Nautical Almanac.ĪPPLICATION FEATURESThe "Lines of Position" module will calculate and plot the fix lines, from user entered data from a sight object (star, sun, moon, or planet) data, to determine the users Latitude and Longitude. The software also includes a graphical map of the night sky, that enables the user to locate the standard stars utilised in celestial navigation.

The LOP traces can be optionally displayed on actual map images (from OpenStreetMaps), that will (optionally) automatically download and save to a user selected directory. The observations are used to automatically fix the users location by "Line of Positions" (LOP). The AstralNav software is designed to calculate the geographical position of a user, from celestial observations, (like those from a sextant).
