Introduction to Navigation

This course introduces students to the basics of nautical navigation. We will begin with the history of navigational techniques. The beginning of the course will cover early types of celestial navigation all the way to modern electronic navigation.

We will also focus on the terminology for understanding a nautical chart. We will cover core concepts like latitude and longitude. These concepts will help us understand basic locational techniques. Then we will study terms for calculating speed, distance, and location. These include degrees, minutes, and seconds. Terms like these have different meanings at sea than they do in other contexts.

By the end of this course, you will be able to plot a ship's bearing, range, or position. You'll learn to calculate the exact fix of a ship using tools such as radar, radio beacons, and GPS. Following that, you'll practice drawing accurate LOPs You will be able to measure how many nautical miles a ship is from shore. Finally, you'll learn to estimate quickly j how many knots it is traveling.

The final exam for this course tests your ability to read charts. You will also have to plot a fix using celestial navigation skills as well as electronic ones.
