By tracking the sun, we can determine local true noon (the point at which the sun is highest in the sky), which can differentiate from the local standardized time by nearly up to an hour, depending on one's location in a time zone. In the northern hemisphere, the direction of the sun at local true noon in turn determines due south. Thus, a celestial navigator could use a quadrant and the sun to calibrate a compass.
On this leg of the Voyage of Discovery, the research team of Alyssa, Harmen, Kortnee, and Laurie studied celestial tracking for their presentation project.
