The Sun Sight Reduction program is designed for navigators who need a backup to their GPS system or for those doing their RYA Ocean Practical to check their workings. No books or tables need be carried.
The program will produce an accurate position line for any date between the years 1900 and 2100.
There is no need with this program to choose a position (CP) so that the DR position can be used, except when using examples from books when the CP must be used.
