Diagram helps students visualize celestial navigation


Sometime celestial navigation teacher James Austin provided us with this diagram he devised to help his students when he taught celestial navigation. Here’s his explanation: “I came up with this diagram to visually illustrate for students the goal of celestial navigation. It’s a way of showing the process of getting a bearing (‘azimuth’) and range (‘altitude’) of the celestial body’s GP from the ship, with the difference between Ho and Hc being the ‘intercept’ along the azimuth. It was devised as a pictorial pathway showing where each of the navigation volumes fit into the process. Most of my students liked the fact that they could look at this diagram to get re-oriented after being mired in numbers. It helped them to be reminded where they were along that path.”
