Celestial & Great Navigation Program

This is a program that allows even the novice to enjoy the skills of a navigator. It provides quick and easy solutions to a variety of navigational problems with entry through a main menu to each of 5 sections/programs. Its use requires no previous knowledge of celestial navigational mathematics. All information is entered by data prompts. A 2 star position fix requires less than a minute to solve and a star bearing only half that time.\n\nOriginal retail price: $24.95 (M.W. Ruth Co. Catalog, October 1987)
