Container Ship Skymate Pro:  The Navigator's Almanac is a computerized Nautical Almanac. Using an internal almanac for the years 1900-2100, Skymate Pro will provide Mariners the accurate information needed for celestial navigation at sea.

To maximize the full potential of Skymate Pro, the user should have a working knowledge and proficiency in the terminology and skills of celestial navigation.
Skymate Pro uses date/time information entered into a DR Toolbar to calculate a number of various almanac functions. The flexibility of the DR Toolbar allows the user to quickly change date/time and position information for the various celestial functions available.  Although features are available to project a DR position to various times and dates, the program does not require you to maintain a DR position in order to calculate the various celestial functions.

Version 1.03 of Skymate Pro fixed a bug that affected calculations to various almanac calculations on PC systems set to various International Settings in Windows.

These almanac functions conflicted with the International/Regional Date Settings in Windows which caused the program to crash or calculate improperly.  If you are still using an early version you should download the latest version.
