OffShoreNavigationVBA Videos for Celestial Navigation | |
This page contains a number of tutorial videos on using the
OffShoreNavigationVBA program, specifically the Celestial
Navigation functions of the program. There is a
separate page for
videos on the Ship Log functions. On the right are links to the videos on this web page. |

Overview | |
The Video below provides an overview of this program | |
Selecting Visible Stars and Planets | |
The Video below covers using the program to select morning and evening objects for celestial sights. This video displays a program bug in that the sorted list of the celestial objects is not correct. My sort obviously does not handle negative numbers correctly. My narration also has a bug. I state that the time of the evening twilight has passed. In that case I should have incremented the date for both the morning and evening lists to the following day. I only advanced the date of the morning list. | |
Reducing a Sun Sight | |
The video below demonstrates using OffShoreNavigationVBA to reduce a Sun sight. | |
Linear Regression Analysis of Multiple Sun Sights | |
The next video shows how to use OffShoreNavigationVBA to perform a linear regression analysis on a series of Sun sights to identify and eliminate errors in the sights. | |
Generate a Position Fix from Multiple Lines of Position (LOP) | |
This video covers using the program to generate a position fix based on a series of LOP - Sun, Star, Panet or Moon sights. | |
Reducing a Star Sight | |
The video below demonstrates using the program to reduce a star sight. | |
Reducing a Planet Sight | |
This video covers using the program to reduce a planet sight. | |
Reducing a Moon Sight | |
The following video covers reducing a Moon sight with this program. This sight reduction requires the use of a curren Nautical Almanac. | |
Calculating the Time of Moon Rise/Set/Meridian Passage | |
This video demonstrates how to use the program to calculate various phenomenom of the Moon. I actually made a typo error in this video when entering the Moon Set times from the Nautical Alamanc. If I had inspected the results a little more carefully I would have detected the error and corrected the entry. | |
Printing Daily Pages Similar to Those in the Nautical Almanac | |
The program can be used to print almanac data similar to the daily pages of the Nautical Almanac. The missing item from this report is the Moon data. | |
