What is the term for navigating from one point to another using only time, speed, and distance calculations?

The term for navigating from one point to another using only time, speed, and distance calculations is dead reckoning. This method involves calculating one's current position by estimating the distance traveled over a specific period, factoring in the speed of travel and the time elapsed. Navigators using dead reckoning will maintain a log of their course and speed, which helps them to project their position based solely on these calculations without any reliance on visible landmarks or external aids.

This technique is especially useful in situations where other forms of navigation, such as visual navigation or instrument navigation, may not be available. Ultimately, dead reckoning relies on the foundational principles of mathematics and physics, applying straightforward calculations to ensure safe and efficient navigation.
