Design Considerations for a Celestial Navigation Trainer

This paper gives a short history of the need for navigation training and tells what a navigator should know. It also tells how navigators were trained in the middle ages and of training devices used then as well as explaining the requirements of the modern celestial navigation trainer and how the 1A19 meets these requirements. It explains, in general engineering terms, the techniques used for simulation of motion and references and changes in references required for navigating.
